I am trying to change the font of the placeholder text in the search bar within my Search Display Controller. I was looking at some examples and I tried to implement them but as they are in Objective-C, I wasn't able to find any that I could get to work.
For example, I tried this one:
UITextField *textField = [[searchBar subviews] objectAtIndex:1];
[textField setFont:[UIFont fontWithName:#"Helvetica" size:40]];
But I was unable to get past var textField: UITextField = UISearchBar
Any ideas?
//SearchBar Text
let textFieldInsideUISearchBar = dashBoardSearchBar.valueForKey("searchField") as? UITextField
textFieldInsideUISearchBar?.textColor = UIColor.whiteColor()
//SearchBar Placeholder
let textFieldInsideUISearchBarLabel = textFieldInsideUISearchBar!.valueForKey("placeholderLabel") as? UILabel
textFieldInsideUISearchBarLabel?.textColor = UIColor.whiteColor()
Set placeholder text font size:
UILabel.appearance(whenContainedInInstancesOf: [UISearchBar.self]).font = UIFont.systemFont(ofSize: 12)
set search text font size:
UITextField.appearance(whenContainedInInstancesOf: [UISearchBar.self]).font = UIFont.systemFont(ofSize: 12)
This is the easiest practise for changing the Font or any other similar changes in the textfield of searchBar. I have been using XCode 8.4, Swift 3.x, iOS 10.x.
extension UISearchBar {
func change(textFont : UIFont?) {
for view : UIView in (self.subviews[0]).subviews {
if let textField = view as? UITextField {
textField.font = textFont
}
}
} }
The above code can be called directly where you make an IBOutlet of the searchBar...
#IBOutlet weak var searchBar: UISearchBar! {
didSet {
searchBar.change(textFont: GlobalConstants.Font.avenirBook14)
}
}
searchBar.searchTextField.font = UIFont(name: "Helvetica", size: 40)
There is even an easier way in Swift 5:
searchBar[keyPath: \.searchTextField].font = UIFont(...)
In iOS 8 ,try this
for subView in searchBar.subviews {
for subsubView in subView.subviews {
if let textField = subsubView as? UITextField {
textField.attributedPlaceholder = NSAttributedString(string:NSLocalizedString("Search", comment:""),
attributes:[NSForegroundColorAttributeName: UIColor.orangeColor()])
}
}
}
Swift 3 version of #Alvin's answer
let textFieldInsideUISearchBar = searchBar.value(forKey: "searchField") as? UITextField
let placeholderLabel = textFieldInsideUISearchBar?.value(forKey: "placeholderLabel") as? UILabel
placeholderLabel?.font = UIFont.systemFont(ofSize: 12.0)
This works perfectly for ios7 -> ios9 using swift 2:
if #available(iOS 9.0, *) {
UITextField.appearanceWhenContainedInInstancesOfClasses([UISearchBar.self]).font = UI.getInstance.tinyFont
} else {
func checkSubview(view:UIView)
for subView in view.subviews {
if subView is UITextField {
let textField = subView as! UITextField
textField.font = UI.getInstance.tinyFont
} else {
checkSubview(subView)
}
}
checkSubview(view)
}
Just replace UI.getInstance.tinyFont by whichever font you want.
let searchBar = UISearchBar()
guard let font = UIFont(name: "Helvetica", size: 40.0) else { return }
let attributedString = NSAttributedString(
string: "Search...",
attributes: [
.font: font
]
)
searchBar.searchTextField.attributedPlaceholder = attributedString

here the screenshot that I want output please check
I want the result like this search bar with background color white and black border
here my code is
override func viewDidAppear(_ animated: Bool) {
super.viewDidAppear(true)
for subView in searchBar.subviews {
if !subView.subviews.contains(where: { $0 as? UITextField != nil }) { continue }
guard let textField = subView.subviews.first(where: { $0 as? UITextField != nil }) as? UITextField else { return }
let placeholder = NSMutableAttributedString(
string: "Search",
attributes: [.font: UIFont(name: "Helvetica", size: 15.0)!,
.foregroundColor: UIColor.gray
])
textField.attributedPlaceholder = placeholder
textField.layer.cornerRadius = textField.frame.size.height / 2
textField.layer.masksToBounds = true
textField.textColor = .black
textField.backgroundColor = .white
}
this is my output screenshot please check it
I am unable to set search bar, please suggest me
Good day! If I understand you correctly, then this may solve your problem. Extension for UISearchBar (Swift 5):
import UIKit
extension UISearchBar {
func setupSearchBar(background: UIColor = .white, inputText: UIColor = .black, placeholderText: UIColor = .gray, image: UIColor = .black) {
self.searchBarStyle = .minimal
self.barStyle = .default
// IOS 12 and lower:
for view in self.subviews {
for subview in view.subviews {
if subview is UITextField {
if let textField: UITextField = subview as? UITextField {
// Background Color
textField.backgroundColor = background
// Text Color
textField.textColor = inputText
// Placeholder Color
textField.attributedPlaceholder = NSAttributedString(string: textField.placeholder ?? "", attributes: [NSAttributedString.Key.foregroundColor : placeholderText])
// Default Image Color
if let leftView = textField.leftView as? UIImageView {
leftView.image = leftView.image?.withRenderingMode(.alwaysTemplate)
leftView.tintColor = image
}
let backgroundView = textField.subviews.first
backgroundView?.backgroundColor = background
backgroundView?.layer.cornerRadius = 10.5
backgroundView?.layer.masksToBounds = true
}
}
}
}
// IOS 13 only:
if let textField = self.value(forKey: "searchField") as? UITextField {
// Background Color
textField.backgroundColor = background
// Text Color
textField.textColor = inputText
// Placeholder Color
textField.attributedPlaceholder = NSAttributedString(string: textField.placeholder ?? "", attributes: [NSAttributedString.Key.foregroundColor : placeholderText])
// Default Image Color
if let leftView = textField.leftView as? UIImageView {
leftView.image = leftView.image?.withRenderingMode(.alwaysTemplate)
leftView.tintColor = image
}
}
}
}
Also, you can try to do it with an image.
The way to do this only using Apple APIs is to create an image and use setSearchFieldBackgroundImage:
self.searchBar.setSearchFieldBackgroundImage(UIImage(named: "SearchFieldBackground"), for: UIControlState.normal)
Source: Cannot change search bar background color
I can change title appearance and its work very well but I can't change prompt font and color
Try this code in viewWillAppear(_ animated: Bool):
for view in self.navigationController?.navigationBar.subviews ?? [] {
let subviews = view.subviews
if subviews.count > 0, let label = subviews[0] as? UILabel {
label.textColor = UIColor.white
label.font = UIFont.systemFont(ofSize: 30)
}
}
I know how to set the appearance for a independent UISearchBar, just like the following.
let searchField = searchBar.value(forKey: "searchField") as? UITextField
if let field = searchField {
field.backgroundColor = UIColor.defaultBackgroundColor
field.layer.cornerRadius = 15.0
field.textColor = .white
field.tintColor = .white
field.font = UIFont.systemFont(ofSize: fl(13))
field.layer.masksToBounds = true
field.returnKeyType = .search
}
But this is not working in the UISearchController.
I want to set the text color of the placeholder and the left magnifying lens icon to pure white.
(It seems there is a colored layer over them now).
In addition, the input text is black now, I want it to be white too.
In a conclusion, I want to modify the following properties.
1. textField background color
2. textFiled placeholder text color
3. textFiled text color
4. textFiled font
Anyone know how do it?
Add the following with your code in viewDidAppear:
let placeholderString = NSAttributedString(string: "Placeholder", attributes: [NSAttributedStringKey.foregroundColor: UIColor.white])
field.attributedPlaceholder = placeholderString
let iconView = field.leftView as! UIImageView
iconView.image = iconView.image?.withRenderingMode(.alwaysTemplate)
iconView.tintColor = .white
Updata:
Put those settings in ViewDidAppear() did solve a part of my problem.
But the textfield's background color changed when I set the bar's background color.
Because searchBar.barTintColor = .red is not working in iOS11's UISearchController embedded in navigation item, I used searchBar.backgroundColor = .red
It confused me a lot.
So how to change searchBar's background and textField's background separately?
set attributedPlaceholder for textfield of search bar
#IBOutlet weak var sbSearchBar: UISearchBar!
if let textfield = sbSearchBar.value(forKey: "searchField") as? UITextField {
textfield.backgroundColor = UIColor.red
textfield.attributedPlaceholder = NSAttributedString(string: textfield.placeholder ?? "", attributes: [NSAttributedStringKey.foregroundColor : UIColor.white])
if let leftView = textfield.leftView as? UIImageView {
leftView.image = leftView.image?.withRenderingMode(.alwaysTemplate)
leftView.tintColor = UIColor.white
}
}
Here is result:
Update:
I think, this may help you: how to change uitextfield color in searchcontroller?
Just apply your color combination in this code and see.
if #available(iOS 11.0, *) {
let sc = UISearchController(searchResultsController: nil)
sc.delegate = self
let scb = sc.searchBar
scb.tintColor = UIColor.white
scb.barTintColor = UIColor.white
if let textfield = scb.value(forKey: "searchField") as? UITextField {
//textfield.textColor = // Set text color
if let backgroundview = textfield.subviews.first {
// Background color
backgroundview.backgroundColor = UIColor.white
// Rounded corner
backgroundview.layer.cornerRadius = 10;
backgroundview.clipsToBounds = true;
}
}
if let navigationbar = self.navigationController?.navigationBar {
navigationbar.barTintColor = UIColor.blue
}
navigationItem.searchController = sc
navigationItem.hidesSearchBarWhenScrolling = false
}
Result:
Add the following with your code in viewDidAppear:
let placeholderString = NSAttributedString(string: "Placeholder", attributes: [NSAttributedStringKey.foregroundColor: UIColor.white])
field.attributedPlaceholder = placeholderString
let iconView = field.leftView as! UIImageView
iconView.image = iconView.image?.withRenderingMode(.alwaysTemplate)
iconView.tintColor = .white
Update - the following is the complete code to customize UISearchController colors:
override func viewDidAppear(_ animated: Bool) {
//sets navigationbar backgroundColor
if let navigationbar = self.navigationController?.navigationBar {
navigationbar.barTintColor = UIColor.magenta
}
let searchField = searchController.searchBar.value(forKey: "searchField") as? UITextField
//sets searchBar backgroundColor
searchController.searchBar.backgroundColor = .blue
if let field = searchField {
field.layer.cornerRadius = 15.0
//sets text Color
field.textColor = .brown
//sets indicator and cancel button Color
field.tintColor = .green
field.font = UIFont.systemFont(ofSize: 13)
field.layer.masksToBounds = true
field.returnKeyType = .search
//sets placeholder text Color
let placeholderString = NSAttributedString(string: "placeholder", attributes: [NSAttributedStringKey.foregroundColor: UIColor.red])
field.attributedPlaceholder = placeholderString
//sets icon Color
let iconView = field.leftView as! UIImageView
iconView.image = iconView.image?.withRenderingMode(.alwaysTemplate)
iconView.tintColor = .cyan
//sets textField backgroundColor
if let backgroundview = field.subviews.first {
backgroundview.backgroundColor = UIColor.yellow
}
}
}
The accepted solution does not work for iOS 13, you are getting the following error (testet with Obj-C Code):
Terminating app due to uncaught exception 'NSGenericException',
reason: 'Access to UISearchBar's _searchField ivar is prohibited. This
is an application bug'
But now you have the option to access UISearchBar's TextField directly, without using a private API.
if (#available(iOS 13, *)) {
self.searchController.searchBar.searchTextField.backgroundColor = [UIColor whiteColor];
self.searchController.searchBar.searchTextField.tintColor = [UIColor darkGrayColor];
}
else {
UITextField *txfSearchField = [self.searchController.searchBar valueForKey:#"_searchField"];
UIView *background = txfSearchField.subviews.firstObject;
background.layer.cornerRadius = 10;
background.clipsToBounds = true;
background.backgroundColor=[UIColor whiteColor];
txfSearchField.tintColor=[UIColor darkGrayColor];
txfSearchField.textColor = [UIColor redColor];
}
I am in process of adding large title in navigation bar in one of the application. The issue is title is little long so I will require to add two lines in large title. How can I add large title with two lines in navigation bar?
This is not about default navigation bar title! This is about large title which is introduced in iOS 11. So make sure you add suggestions by considering large title. Thanks
Based in #krunal answer, this is working for me:
extension UIViewController {
func setupNavigationMultilineTitle() {
guard let navigationBar = self.navigationController?.navigationBar else { return }
for sview in navigationBar.subviews {
for ssview in sview.subviews {
guard let label = ssview as? UILabel else { break }
if label.text == self.title {
label.numberOfLines = 0
label.lineBreakMode = .byWordWrapping
label.sizeToFit()
UIView.animate(withDuration: 0.3, animations: {
navigationBar.frame.size.height = 57 + label.frame.height
})
}
}
}
}
In the UIViewController:
override func viewDidLoad() {
super.viewDidLoad()
self.title = "This is a multiline title"
setupNavigationMultilineTitle()
}
override func viewDidAppear(_ animated: Bool) {
super.viewDidAppear(animated)
setupNavigationMultilineTitle()
}
And for setting font and color on the large title:
navigation.navigationBar.largeTitleTextAttributes = [NSAttributedStringKey.foregroundColor: .red, NSAttributedStringKey.font: UIFont.boldSystemFont(ofSize: 30)]
Get a navigation item subviews and locate UILabel from it.
Try this and see:
self.navigationController?.navigationBar.prefersLargeTitles = true
self.navigationController?.navigationItem.largeTitleDisplayMode = .automatic
self.title = "This is multiline title for navigation bar"
self.navigationController?.navigationBar.largeTitleTextAttributes = [
NSAttributedStringKey.foregroundColor: UIColor.black,
NSAttributedStringKey.font : UIFont.preferredFont(forTextStyle: .largeTitle)
]
for navItem in(self.navigationController?.navigationBar.subviews)! {
for itemSubView in navItem.subviews {
if let largeLabel = itemSubView as? UILabel {
largeLabel.text = self.title
largeLabel.numberOfLines = 0
largeLabel.lineBreakMode = .byWordWrapping
}
}
}
Here is result:
The linebreak solution seems to be problematic when there's a back button. So instead of breaking lines, I made the label auto adjust font.
func setupLargeTitleAutoAdjustFont() {
guard let navigationBar = navigationController?.navigationBar else {
return
}
// recursively find the label
func findLabel(in view: UIView) -> UILabel? {
if view.subviews.count > 0 {
for subview in view.subviews {
if let label = findLabel(in: subview) {
return label
}
}
}
return view as? UILabel
}
if let label = findLabel(in: navigationBar) {
if label.text == self.title {
label.adjustsFontSizeToFitWidth = true
label.minimumScaleFactor = 0.7
}
}
}
Then it needs to be called in viewDidLayoutSubviews() to make sure the label can be found, and we only need to call it once:
private lazy var setupLargeTitleLabelOnce: Void = {[unowned self] in
if #available(iOS 11.0, *) {
self.setupLargeTitleAutoAdjustFont()
}
}()
override func viewDidLayoutSubviews() {
super.viewDidLayoutSubviews()
let _ = setupLargeTitleLabelOnce
}
If there's any navigationController pop event back to this controller, we need to call it again in viewDidAppear(). I haven't found a better solution for this - there's a small glitch of label font changing when coming back from a pop event:
override func viewDidAppear(_ animated: Bool) {
super.viewDidAppear(animated)
if #available(iOS 11.0, *) {
setupLargeTitleAutoAdjustFont()
}
}
You could try:
Create a custom UINavigationController
Add the protocol UINavigationBarDelegate to the class definition
Override the function navigationBar(_:shouldPush:)
Activate two lines mode using hidden variable item.setValue(true, forKey: "__largeTitleTwoLineMode")
Make navigationController.navigationBar.prefersLargeTitles = true
(Edit 7/13: I notice that this solution is not support scrollView, so now I'm in research)
I found a perfect solution on Swift5
but sorry for my poor English because I'm Japanese🇯🇵Student.
In case of 2 lines In case of 3 lines
At first, set navigation settings for largeTitle normally in viewDidLoad
//Set largeTitle
navigationItem.largeTitleDisplayMode = .automatic
navigationController?.navigationBar.prefersLargeTitles = true
navigationController?.navigationBar.largeTitleTextAttributes = [.font: UIFont.systemFont(ofSize: (fontSize + margin) * numberOfLines)]//ex) fontSize=26, margin=5, numberOfLines=2
//Set title
title = "multiple large\ntitle is working!"
It is most important point of this solution that font-size at largeTitleTextAttributes equals actual font-size(+margin) multiplied by number of lines.
Description image
Because, default specification of navigationBar attributes may be able to display only 1 line largeTitle.
Although, somehow, I did notice that in case of label-settings(the label which subview of subview of navigationBar) on direct, it can display any number of lines in 1 line of in case of navigationBar attributes.
So, we should do set big font in navigationbar attributes, and set small font in the label(subview of subview of navigationBar), and take into consideration the margins.
Do label settings direct in viewDidAppear like this:
//Find label
navigationController?.navigationBar.subviews.forEach({ subview in
subview.subviews.forEach { subsubview in
guard let label: UILabel = subsubview as? UILabel else { return }
//Label settings on direct.
label.text = title
label.font = UIFont.systemFont(ofSize: fontSize)
label.numberOfLines = 0
label.lineBreakMode = .byWordWrapping
label.sizeToFit()
}
})
Therefore, in short, the solution at minimum code is given like this:
import UIKit
class ViewController: UIViewController {
private let fontSize: CGFloat = 26, margin: CGFloat = 5
private let numberOfLines: CGFloat = 2
override func viewDidLoad() {
super.viewDidLoad()
setUpNavigation()
}
override func viewDidAppear(_ animated: Bool) {
super.viewDidAppear(animated)
setMultipleLargeTitle()
}
private func setUpNavigation() {
//Set largeTitle
navigationItem.largeTitleDisplayMode = .automatic
navigationController?.navigationBar.prefersLargeTitles = true
navigationController?.navigationBar.largeTitleTextAttributes = [.font: UIFont.systemFont(ofSize: (fontSize + margin) * numberOfLines)]
//Set title
title = "multiple large\ntitle is working!"
}
private func setMultipleLargeTitle() {
//Find label
navigationController?.navigationBar.subviews.forEach({ subview in
subview.subviews.forEach { subsubview in
guard let label: UILabel = subsubview as? UILabel else { return }
//Label settings on direct.
label.text = title
label.font = UIFont.systemFont(ofSize: fontSize)
label.numberOfLines = 0
label.lineBreakMode = .byWordWrapping
label.sizeToFit()
}
})
}
}
thank you for reading :)
Swift 4 : Multi line even though the sentence is only short
title = "You're \nWelcome"
for navItem in(self.navigationController?.navigationBar.subviews)! {
for itemSubView in navItem.subviews {
if let largeLabel = itemSubView as? UILabel {
largeLabel.text = self.title
largeLabel.numberOfLines = 0
largeLabel.lineBreakMode = .byWordWrapping
}
}
}
If anyone looking for Title Lable Not Large Title, then below code is working.
Swift 5.X
func setMultilineNavigationBar(topText: String, bottomText : String) {
let topTxt = NSLocalizedString(topText, comment: "")
let bottomTxt = NSLocalizedString(bottomText, comment: "")
let titleParameters = [NSAttributedString.Key.foregroundColor : UIColor.white,
NSAttributedString.Key.font : UIFont.systemFont(ofSize: 16, weight: .semibold)]
let subtitleParameters = [NSAttributedString.Key.foregroundColor : UIColor.white,
NSAttributedString.Key.font : UIFont.systemFont(ofSize: 13, weight: .regular)]
let title:NSMutableAttributedString = NSMutableAttributedString(string: topTxt, attributes: titleParameters)
let subtitle:NSAttributedString = NSAttributedString(string: bottomTxt, attributes: subtitleParameters)
title.append(NSAttributedString(string: "\n"))
title.append(subtitle)
let size = title.size()
let width = size.width
guard let height = navigationController?.navigationBar.frame.size.height else {return}
let titleLabel = UILabel(frame: CGRect.init(x: 0, y: 0, width: width, height: height))
titleLabel.attributedText = title
titleLabel.numberOfLines = 0
titleLabel.textAlignment = .center
self.navigationItem.titleView = titleLabel
}
SWIFT 5 This UIViewController extension helped me. Scenario that I have is mixed with enabling and disabling large titles so FIRST ENABLE large title and then call this method. Call it in viewDidLoad, I have found bug with peeking back with swipe and then releasing touch, for some reason current navigation title become previous navigation title
extension UIViewController {
/// Sets two lines for navigation title if needed
/// - Parameter animated: used for changing titles on one controller,in that case animation is off
func multilineNavTitle(_ animated:Bool = true) {
if animated {
// setting initial state for animation of title to look more native
self.navigationController?.navigationBar.transform = CGAffineTransform.init(translationX: .screenWidth/2, y: 0)
self.navigationController?.navigationBar.alpha = 0
}
//Checks if two lines is needed
if self.navigationItem.title?.forTwoLines() ?? false {
// enabling multiline
navigationItem.setValue(true,
forKey: "__largeTitleTwoLineMode")
} else {
// disabling multiline
navigationItem.setValue(false,
forKey: "__largeTitleTwoLineMode")
}
// laying out title without animation
UIView.performWithoutAnimation {
self.navigationController?.navigationBar.layoutSubviews()
self.navigationController?.view.setNeedsLayout()
self.navigationController?.view.layoutIfNeeded()
}
if animated {
//animating title
UIView.animate(withDuration: 0.3) {
self.navigationController?.navigationBar.transform = CGAffineTransform.identity
self.navigationController?.navigationBar.alpha = 1
}
}
}
}
fileprivate extension String {
/// Checks if navigation title is wider than label frame
/// - Returns: `TRUE` if title cannot fit in one line of navigation title label
func forTwoLines() -> Bool {
let fontAttributes = [NSAttributedString.Key.font: SomeFont]
let size = self.size(withAttributes: fontAttributes)
return size.width > CGFloat.screenWidth - 40 //in my case
}
}
Just create a custom navigation controller. Rest will be handled by the OS itself
class MyNavigationViewController: UINavigationController {
override func viewDidLoad() {
super.viewDidLoad()
navigationBar.delegate = self
}
}
extension MyNavigationViewController: UINavigationBarDelegate {
func navigationBar(_ navigationBar: UINavigationBar, shouldPush item: UINavigationItem) -> Bool {
item.setValuesForKeys([
"__largeTitleTwoLineMode": true
])
return true
}
}
viewController.navigationItem
.setValuesForKeys(["__largeTitleTwoLineMode": true])
WARNING: This method does not work on older OS versions
I was wondering if it is possible to create a UIButton with two lines of text. I need each line to have a different font size. The first line will be 17 point and the second will be 11 point. I've tried messing with putting two labels inside of a UIButton, but I can't get them to stay inside the bounds of the button.
I'm attempting to do all of this in the ui builder, and not programmatically.
Thanks
There are two questions.
I was wondering if it is possible to create a UIButton with two lines
of text
This is possible through using the storyboard or programmatically.
Storyboard:
Change the 'Line Break Mode' to Character Wrap or Word Wrap and use Alt/Option + Enter key to enter a new line in the UIButton's Title field.
Programmatically:
override func viewDidAppear(animated: Bool) {
super.viewDidAppear(animated)
btnTwoLine?.titleLabel?.lineBreakMode = NSLineBreakMode.ByWordWrapping;
}
I need each line to have a different font size
1
The worst case is, you can use a custom UIButton class and add two labels within it.
The better way is, make use of NSMutableAttributedString. Note that,this can be achieved through only programmatically.
Swift 5:
#IBOutlet weak var btnTwoLine: UIButton?
override func viewDidAppear(animated: Bool) {
super.viewDidAppear(animated)
//applying the line break mode
textResponseButton?.titleLabel?.lineBreakMode = NSLineBreakMode.byWordWrapping;
let buttonText: NSString = "hello\nthere"
//getting the range to separate the button title strings
let newlineRange: NSRange = buttonText.range(of: "\n")
//getting both substrings
var substring1 = ""
var substring2 = ""
if(newlineRange.location != NSNotFound) {
substring1 = buttonText.substring(to: newlineRange.location)
substring2 = buttonText.substring(from: newlineRange.location)
}
//assigning diffrent fonts to both substrings
let font1: UIFont = UIFont(name: "Arial", size: 17.0)!
let attributes1 = [NSMutableAttributedString.Key.font: font1]
let attrString1 = NSMutableAttributedString(string: substring1, attributes: attributes1)
let font2: UIFont = UIFont(name: "Arial", size: 11.0)!
let attributes2 = [NSMutableAttributedString.Key.font: font2]
let attrString2 = NSMutableAttributedString(string: substring2, attributes: attributes2)
//appending both attributed strings
attrString1.append(attrString2)
//assigning the resultant attributed strings to the button
textResponseButton?.setAttributedTitle(attrString1, for: [])
}
Older Swift
#IBOutlet weak var btnTwoLine: UIButton?
override func viewDidAppear(animated: Bool) {
super.viewDidAppear(animated)
//applying the line break mode
btnTwoLine?.titleLabel?.lineBreakMode = NSLineBreakMode.ByWordWrapping;
var buttonText: NSString = "hello\nthere"
//getting the range to separate the button title strings
var newlineRange: NSRange = buttonText.rangeOfString("\n")
//getting both substrings
var substring1: NSString = ""
var substring2: NSString = ""
if(newlineRange.location != NSNotFound) {
substring1 = buttonText.substringToIndex(newlineRange.location)
substring2 = buttonText.substringFromIndex(newlineRange.location)
}
//assigning diffrent fonts to both substrings
let font:UIFont? = UIFont(name: "Arial", size: 17.0)
let attrString = NSMutableAttributedString(
string: substring1 as String,
attributes: NSDictionary(
object: font!,
forKey: NSFontAttributeName) as [NSObject : AnyObject])
let font1:UIFont? = UIFont(name: "Arial", size: 11.0)
let attrString1 = NSMutableAttributedString(
string: substring2 as String,
attributes: NSDictionary(
object: font1!,
forKey: NSFontAttributeName) as [NSObject : AnyObject])
//appending both attributed strings
attrString.appendAttributedString(attrString1)
//assigning the resultant attributed strings to the button
btnTwoLine?.setAttributedTitle(attrString, forState: UIControlState.Normal)
}
Output
I was looking for nearly the same topic, except that I don't need two different font sizes. In case someone is looking for a simple solution:
let button = UIButton()
button.titleLabel?.numberOfLines = 0
button.titleLabel?.lineBreakMode = .byWordWrapping
button.setTitle("Foo\nBar", for: .normal)
button.titleLabel?.textAlignment = .center
button.sizeToFit()
button.addTarget(self, action: #selector(rightBarButtonTapped), for: .allEvents)
navigationItem.rightBarButtonItem = UIBarButtonItem(customView: button)
I have notice an issue in most of the solutions which is while making line break mode to "Character Wrap" the second line will be left aligned to the first line
To make all the lines centered.
just change the title From Plain to Attributed and then you can make each line centered
change line break to character wrap , select your button and in attribute inspector go to line break and change it to character wrap
SWIFT 3 Syntax
let str = NSMutableAttributedString(string: "First line\nSecond Line")
str.addAttribute(NSFontAttributeName, value: UIFont.systemFont(ofSize: 17), range: NSMakeRange(0, 10))
str.addAttribute(NSFontAttributeName, value: UIFont.systemFont(ofSize: 12), range: NSMakeRange(11, 11))
button.setAttributedTitle(str, for: .normal)
I have fixed this and my solution it was only in the Storyboard.
Changes:
It added in Identity Inspector -> User Defined Runtime Attributes (these KeyPaths):
numberOfLines = 2
titleLabel.textAlignment = 1
User Defined Runtime Attributes
I added this in attributes inspector:
line break = word wrap
Word wrap
You need to do some of this in code. you can't set 2 different fonts in IB. In addition to changing the line break mode to character wrap, you need something like this to set the title,
override func viewDidLoad() {
super.viewDidLoad()
var str = NSMutableAttributedString(string: "First line\nSecond Line")
str.addAttribute(NSFontAttributeName, value: UIFont.systemFontOfSize(17), range: NSMakeRange(0, 10))
str.addAttribute(NSFontAttributeName, value: UIFont.systemFontOfSize(12), range: NSMakeRange(11, 11))
button.setAttributedTitle(str, forState: .Normal)
}
New with Xcode 13 (iOS 15)
Starting with Xcode 13, the button's title and subtitle may have their attributes set separately.
Using Storyboard:
In the Attribute Inspector for the button, select "Attributed" by Title. Then change font size of the title and the subtitle.
Or Programmatically:
// Create Title
let titleSettings = AttributeContainer.font( UIFont(name: "HelveticaNeue-Italic", size: 17)! )
yourButton.configuration?.attributedTitle = AttributedString("Button's Title", attributes: titleSettings)
// Create Subtitle
let subtitleSettings = AttributeContainer.font( UIFont(name: "HelveticaNeue-Italic", size: 11)! )
yourButton.configuration?.attributedSubtitle = AttributedString("Button's Subtitle", attributes: subtitleSettings)
One way to do it is with labels, I guess. I did this, and it seems to work ok. I could create this as a UIButton and then expose the labels, I guess. I don't know if this makes any sense.
let firstLabel = UILabel()
firstLabel.backgroundColor = UIColor.lightGrayColor()
firstLabel.text = "Hi"
firstLabel.textColor = UIColor.blueColor()
firstLabel.textAlignment = NSTextAlignment.Center
firstLabel.frame = CGRectMake(0, testButton.frame.height * 0.25, testButton.frame.width, testButton.frame.height * 0.2)
testButton.addSubview(firstLabel)
let secondLabel = UILabel()
secondLabel.backgroundColor = UIColor.lightGrayColor()
secondLabel.textColor = UIColor.blueColor()
secondLabel.font = UIFont(name: "Arial", size: 12)
secondLabel.text = "There"
secondLabel.textAlignment = NSTextAlignment.Center
secondLabel.frame = CGRectMake(0, testButton.frame.height * 0.5, testButton.frame.width, testButton.frame.height * 0.2)
testButton.addSubview(secondLabel)
The suggested solutions unfortunately did not work out for me when I wanted to have a mutliline button inside a CollectionView. Then a colleague showed me a workaround which I wanted to share in case someone has the same problem - hope this helps! Create a class which inherits from UIControl and extend it with a label, which will then behave similar like a button.
class MultilineButton: UIControl {
let label: UILabel = {
$0.translatesAutoresizingMaskIntoConstraints = false
$0.numberOfLines = 0
$0.textAlignment = .center
return $0
}(UILabel())
override init(frame: CGRect) {
super.init(frame: frame)
addSubview(label)
NSLayoutConstraint.activate([
label.leadingAnchor.constraint(equalTo: layoutMarginsGuide.leadingAnchor),
label.trailingAnchor.constraint(equalTo: layoutMarginsGuide.trailingAnchor),
label.topAnchor.constraint(equalTo: layoutMarginsGuide.topAnchor),
label.bottomAnchor.constraint(equalTo: layoutMarginsGuide.bottomAnchor)
])
}
override var isHighlighted: Bool {
didSet {
backgroundColor = backgroundColor?.withAlphaComponent(isHighlighted ? 0.7 : 1.0)
label.textColor = label.textColor.withAlphaComponent(isHighlighted ? 0.7 : 1.0)
}
}
required init?(coder: NSCoder) {
fatalError("init(coder:) has not been implemented")
}
}
my way:
func setButtonTitle(title: String, subtitle: String, button: UIButton){
//applying the line break mode
button.titleLabel?.lineBreakMode = NSLineBreakMode.byWordWrapping;
let title = NSMutableAttributedString(string: title, attributes: Attributes.biggestLabel)
let subtitle = NSMutableAttributedString(string: subtitle, attributes: Attributes.label)
let char = NSMutableAttributedString(string: "\n", attributes: Attributes.biggestLabel)
title.append(char)
title.append(subtitle)
button.setAttributedTitle(title, for: .normal)
}
