I am trying to set an Image for bar button Item for that I have an image like:
with resolution 30 * 30 but while I assign this Image to Bar button Its looks like:
I have assigned image this way :
and If I try this way like making an IBOutlet for the button and set Image programatically form this question and code for that is:
// Outlet for bar button
#IBOutlet weak var fbButton: UIBarButtonItem!
// Set Image for bar button
var backImg: UIImage = UIImage(named: "fb.png")!
fbButton.setBackgroundImage(backImg, forState: .Normal, barMetrics: .Default)
but nothing happend with this,
Can anybody tell me what I am doing wrong?
or which is the batter way to do this?
I have achieved that programatically with this code:
import UIKit
class ViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
//create a new button
let button: UIButton = UIButton.buttonWithType(UIButtonType.Custom) as! UIButton
//set image for button
button.setImage(UIImage(named: "fb.png"), forState: UIControlState.Normal)
//add function for button
button.addTarget(self, action: "fbButtonPressed", forControlEvents: UIControlEvents.TouchUpInside)
//set frame
button.frame = CGRectMake(0, 0, 53, 31)
let barButton = UIBarButtonItem(customView: button)
//assign button to navigationbar
self.navigationItem.rightBarButtonItem = barButton
}
//This method will call when you press button.
func fbButtonPressed() {
println("Share to fb")
}
}
And result will be:
Same way you can set button for left side too this way:
self.navigationItem.leftBarButtonItem = barButton
And result will be:
And if you want same transaction as navigation controller have when you go back with default back button then you can achieve that with custom back button with this code:
func backButtonPressed(sender:UIButton) {
navigationController?.popViewControllerAnimated(true)
}
For swift 3.0:
import UIKit
class ViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
//create a new button
let button = UIButton.init(type: .custom)
//set image for button
button.setImage(UIImage(named: "fb.png"), for: UIControlState.normal)
//add function for button
button.addTarget(self, action: #selector(ViewController.fbButtonPressed), for: UIControlEvents.touchUpInside)
//set frame
button.frame = CGRect(x: 0, y: 0, width: 53, height: 51)
let barButton = UIBarButtonItem(customView: button)
//assign button to navigationbar
self.navigationItem.rightBarButtonItem = barButton
}
//This method will call when you press button.
func fbButtonPressed() {
print("Share to fb")
}
}
For swift 4.0:
import UIKit
class ViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
//create a new button
let button = UIButton(type: .custom)
//set image for button
button.setImage(UIImage(named: "fb.png"), for: .normal)
//add function for button
button.addTarget(self, action: #selector(fbButtonPressed), for: .touchUpInside)
//set frame
button.frame = CGRect(x: 0, y: 0, width: 53, height: 51)
let barButton = UIBarButtonItem(customView: button)
//assign button to navigationbar
self.navigationItem.rightBarButtonItem = barButton
}
//This method will call when you press button.
#objc func fbButtonPressed() {
print("Share to fb")
}
}
An easy solution may be the following
barButtonItem.image = UIImage(named: "image")
then go to your Assets.xcassets select the image and go to the Attribute Inspector and select "Original Image" in Reder as option.
Similar to the accepted solution, but you can replace the
let button: UIButton = UIButton.buttonWithType(UIButtonType.Custom) as! UIButton
with
let button = UIButton()
Here is the full solution, enjoy: (it's just a bit cleaner than the accepted solution)
let button = UIButton()
button.frame = CGRectMake(0, 0, 51, 31) //won't work if you don't set frame
button.setImage(UIImage(named: "fb"), forState: .Normal)
button.addTarget(self, action: Selector("fbButtonPressed"), forControlEvents: .TouchUpInside)
let barButton = UIBarButtonItem()
barButton.customView = button
self.navigationItem.rightBarButtonItem = barButton
Here's a simple extension on UIBarButtonItem:
extension UIBarButtonItem {
class func itemWith(colorfulImage: UIImage?, target: AnyObject, action: Selector) -> UIBarButtonItem {
let button = UIButton(type: .custom)
button.setImage(colorfulImage, for: .normal)
button.frame = CGRect(x: 0.0, y: 0.0, width: 44.0, height: 44.0)
button.addTarget(target, action: action, for: .touchUpInside)
let barButtonItem = UIBarButtonItem(customView: button)
return barButtonItem
}
}
Only two Lines of code required for this
Swift 3.0
let closeButtonImage = UIImage(named: "ic_close_white")
navigationItem.rightBarButtonItem = UIBarButtonItem(image: closeButtonImage, style: .plain, target: self, action: #selector(ResetPasswordViewController.barButtonDidTap(_:)))
func barButtonDidTap(_ sender: UIBarButtonItem)
{
}
I am using latest swift (2.1) and the answer (Dharmesh Kheni and jungledev) does not work for me. The image color was off (when setting in IB, it was blue and when setting directly in UIButton, it was black). It turns out I could create the same bar item with the following code:
let barButton = UIBarButtonItem(image: UIImage(named: "menu"), landscapeImagePhone: nil, style: .Done, target: self, action: #selector(revealBackClicked))
self.navigationItem.leftBarButtonItem = barButton
You can use this code for multiple bar button with custom image:
self.navigationItem.leftBarButtonItem = nil
let button = UIButton(type: .custom)
button.setImage(UIImage (named: "ChatTab"), for: .normal)
button.frame = CGRect(x: 0.0, y: 0.0, width: 35.0, height: 35.0)
//button.addTarget(target, action: nil, for: .touchUpInside)
let barButtonItem = UIBarButtonItem(customView: button)
let button2 = UIButton(type: .custom)
button2.setImage(UIImage (named: "ActivityTab"), for: .normal)
button2.frame = CGRect(x: 0.0, y: 0.0, width: 35.0, height: 35.0)
//button.addTarget(target, action: nil, for: .touchUpInside)
let barButtonItem2 = UIBarButtonItem(customView: button2)
self.navigationItem.rightBarButtonItems = [barButtonItem, barButtonItem2]
Result will be this:
Initialize barbuttonItem like following:
let pauseButton = UIBarButtonItem(image: UIImage(named: "big"),
style: .plain,
target: self,
action: #selector(PlaybackViewController.pause))
Your problem is because of the way the icon has been made - it doesn't conform to Apple's custom tab bar icon specs:
To design a custom bar icon, follow these guidelines:
Use pure white with appropriate alpha transparency.
Don’t include a drop shadow.
Use antialiasing.
(From the guidelines.)
Something that would be possible looks like this. You can find such icons on most free tab bar icon sites.
Swift 4.
#IBOutlet weak var settingBarBtn: UIBarButtonItem! {
didSet {
let imageSetting = UIImageView(image: UIImage(named: "settings"))
imageSetting.image = imageSetting.image!.withRenderingMode(.alwaysOriginal)
imageSetting.tintColor = UIColor.clear
settingBarBtn.image = imageSetting.image
}
}
SwiftUI
.navigationBarItems modifier takes any view you want:
struct ContentView: View {
var body: some View {
NavigationView {
Text("SwiftUI")
.navigationBarItems(leading:
HStack {
Image(systemName: "trash")
Text("Trash")
}
)
}
}
}
.navigationBarItems(trailing: Image(systemName: "trash") )
.navigationBarItems(leading: Image(systemName: "trash.fill"),
trailing: Image(systemName: "trash")
)
You can use a button for each if you need an action for each of them.
Swift 5+. Smooth solution to add ideal image as you desired dynamic Solution
func rightBarButtonItem(iconNameButton: String, selector: Selector) {
let button = UIButton()
button.frame = CGRect(x: 0, y: 0, width: 25, height: 25)
button.setImage(UIImage(named: iconNameButton), for: .normal)
button.addTarget(self, action: selector, for: .touchUpInside)
button.imageView?.contentMode = .scaleAspectFit
let buttonBarButton = UIBarButtonItem(customView: UIView(frame: CGRect(x: 0, y: 0, width: 25, height: 25)))
buttonBarButton.customView?.addSubview(button)
buttonBarButton.customView?.frame = button.frame
self.navigationItem.rightBarButtonItem = buttonBarButton
}
Just choose Original image option when adding an image to assets in Xcode
If your UIBarButtonItem is already allocated like in a storyboard.
(printBtn)
let btn = UIButton(frame: CGRect(x: 0, y: 0, width: 30, height: 30))
btn.setImage(UIImage(named: Constants.ImageName.print)?.withRenderingMode(.alwaysTemplate), for: .normal)
btn.addGestureRecognizer(UITapGestureRecognizer(target: self, action: #selector(handlePrintPress(tapGesture:))))
printBtn.customView = btn
If you have set up your UIBarButtonItem with an image in the storyboard, one small hack to change the renderingMode is to add the following code to your viewDidLoad(). This way you don't have to resort to adding the entire button and image in code.
if let navButton = self.navigationItem.leftBarButtonItem, let buttonImage = navButton.image {
navButton.image = buttonImage.withRenderingMode(.alwaysOriginal)
}
navigationItem.rightBarButtonItem = UIBarButtonItem(title: "Left",
style: .plain,target: self, action: #selector(rightbarButtonAction))
navigationItem.rightBarButtonItem?.image = UIImage(named: "Notification Bell")
I'm learning Swift and I wanted to make a Menu that is common to all pages. How do I do it? Currently, I'm manually adding a 'menu button' on each page and add an action to toggle the menu. By the way I'm using this library called ENSideMenu. The menu looks like this.
You should create one common class for that, and just call that function. Here is the example.
Call below function in your view did load method
CommonSingleton.sharedInstance.setNavigationItem(itemTitleName: "Menu", navigationItem: self.navigationItem, actionBtn: #selector(self.sideMenuBtnPressed), target: self)
Create one swift file, named CommonSingleton
import UIKit
import Firebase
private let sharedToken = CommonSingleton()
class CommonSingleton {
class var sharedInstance: CommonSingleton {
return sharedToken
}
func setNavigationItem(itemTitleName: String, navigationItem:UINavigationItem, actionBtn:Selector,target:Any ){
if(itemTitleName=="Refresh"){
// navigationItem.rightBarButtonItem = UIBarButtonItem(barButtonSystemItem: .refresh, target: target, action: actionBtn)
let btnCreateBid: UIButton = UIButton()
let image = UIImage(named: "navRefresh")
btnCreateBid.setImage(image, for: .normal)
btnCreateBid.frame = CGRect(x: 0, y: 0, width: (image?.size.width)!, height: (image?.size.height)!)
btnCreateBid.addTarget(target, action: actionBtn, for: .touchUpInside)
btnCreateBid.layer.cornerRadius = 4.0
btnCreateBid.clipsToBounds = true
let rightItem:UIBarButtonItem = UIBarButtonItem()
rightItem.customView = btnCreateBid
rightItem.customView?.layer.cornerRadius=5.0
navigationItem.rightBarButtonItem = rightItem
}
else if(itemTitleName=="Done"){
navigationItem.rightBarButtonItem = UIBarButtonItem(barButtonSystemItem: .done, target: target, action: actionBtn)
}
else if (itemTitleName=="Back") {
let btnCreateBid: UIButton = UIButton()
let image = UIImage(named: "icons_Back")
btnCreateBid.setImage(image, for: .normal)
btnCreateBid.frame = CGRect(x: 0, y: 0, width: (image?.size.width)!, height: (image?.size.height)!)
btnCreateBid.addTarget(target, action: actionBtn, for: .touchUpInside)
btnCreateBid.layer.cornerRadius = 4.0
btnCreateBid.clipsToBounds = true
let rightItem:UIBarButtonItem = UIBarButtonItem()
rightItem.customView = btnCreateBid
rightItem.customView?.layer.cornerRadius=5.0
navigationItem.leftBarButtonItem = rightItem
}
else if(itemTitleName=="Menu"){
let menuButton = UIBarButtonItem(image: UIImage(named: "menu"), style: .plain, target: target, action: actionBtn)
navigationItem.leftBarButtonItem = menuButton
}
else if(itemTitleName=="CreateBid"){
let btnCreateBid: UIButton = UIButton()
btnCreateBid.setImage(UIImage(named: "create_bid"), for: .normal)
btnCreateBid.frame = CGRect(x: 0, y: 0, width: 30, height: 30)
btnCreateBid.addTarget(target, action: actionBtn, for: .touchUpInside)
btnCreateBid.layer.cornerRadius = 4.0
btnCreateBid.clipsToBounds = true
let rightItem:UIBarButtonItem = UIBarButtonItem()
rightItem.customView = btnCreateBid
rightItem.customView?.layer.cornerRadius=5.0
navigationItem.rightBarButtonItem = rightItem
}
else if(itemTitleName=="MoreOption"){
navigationItem.rightBarButtonItem = UIBarButtonItem(image: UIImage(named: "ic_more_vert_"), style: .plain, target: target, action: actionBtn)
}
}
}
This can be simply done by creating a superview controller and on its viewdidload create a button and assign an action to it.
I have created a menu slider in swift 3.0 here
Use it as a reference if you want.
Thanks
The library currently doesn't support 2 menus in the same page
I am trying to create a custom navigationBar.
I am hiding the original navigationBar in viewWillAppear like so:
override func viewWillAppear(_ animated: Bool) {
self.navigationController?.isNavigationBarHidden = true
}
I am subclassing UINavigationBar like so:
let navBar: UINavigationBar = {
let view = UINavigationBar()
view.backgroundColor = .clear
view.isTranslucent = true
view.translatesAutoresizingMaskIntoConstraints = false
return view
}()
In viewDidLoad I am calling setupNavBar():
func setupNavBar() {
view.addSubview(navBar)
self.navBar.frame = CGRect(x: 0, y: 0, width: view.frame.width, height: 80)
let backButton = UIBarButtonItem(image: UIImage(named:"backThick"), style: .plain, target: self, action: #selector(popControllerOffStack))
}
The problem is that backButton is added to the original navigationBar that is being hidden. This makes me think I am incorrectly creating the navigationBar. How do I add the button to navBar?
Updated Code (still not working):
class CustomNavBar: UINavigationBar {
override init(frame: CGRect) {
super.init(frame: frame)
self.backgroundColor = .red
}
}
// In the viewController
let navBar = CustomNavBar()
override func viewDidLoad() {
super.viewDidLoad()
setupNavBar()
}
func setupNavBar() {
view.addSubview(navBar)
navBar.frame = CGRect(x: 0, y: 0, width: view.frame.width, height: 80)
let backButton = UIBarButtonItem(image: UIImage(named:"backThick"), style: .plain, target: self, action: #selector(popControllerOffStack))
self.navigationItem.leftBarButtonItem = backButton
}
The button is being added to the original navigationBar.
You are not subclassing UINavigationBar. Rather, you are creating a new instance of UINavigationBar and modifying its properties inside a computed variable. This means each time you access navBar, you are initializing a new UINavigationBar object.
To create a subclass:
class MyCustomNavigationBar: UINavigationBar {
// Set properties in here after initialization
}
Once you have a proper subclass created, You can initialize an instance like so:
var navBar = MyCustomNavigationBar()
Finally, add your button to the navigation bar:
let backButton = UIBarButtonItem(image: UIImage(named:"backThick"), style: .plain, target: self, action: #selector(popControllerOffStack))
// Assuming 'self' is an instance of UINavigationController()
self.navigationItem.leftBarButtonItem = backButton
See the official Swift Programming Language Guide on Inheritance.
Swift 3.0
You can set custom Back button as like below
self.navigationItem.hidesBackButton = true
let backButton = UIBarButtonItem(image: UIImage(named: "image_name"), style: .plain, target: self, action: #selector(Class.methodName))
backButton.tintColor = UIColor.white
self.navigationItem.leftBarButtonItem = backButton
Also you can try below code:
let btnLeftMenu: UIButton = UIButton()
btnLeftMenu.setImage(UIImage(named: "image_name"), for:UIControlState())
btnLeftMenu.addTarget(self, action: #selector(moveImage), for:UIControlEvents.touchUpInside)
btnLeftMenu.frame = CGRect(x: 0, y: 0, width: 25, height: 25)
let barButton = UIBarButtonItem(customView: btnLeftMenu)
self.navigationItem.leftBarButtonItem = barButton*
I try to add custom back button in navigation controller. I create button like this
func setupBackButton() {
let backButton = UIButton.init(type: .custom)
backButton.addTarget(self, action: #selector(backButtonHandler(_:)), for: .touchUpInside)
backButton.setTitleColor(UIColor.white, for: .normal)
backButton.setTitle("<", for: .normal)
backButton.tintColor = UIColor.white
let barBackButton = UIBarButtonItem(customView: backButton)
self.navigationItem.leftBarButtonItem = barBackButton
}
The problem is that button is being added (I can tap it and action on button is being executed) but i can't see button in controller - it is invisible.
Controller's color is blue.
you missed the frame of your button
backButton.frame = CGRect(x: 0, y: 0, width: 44, height: 44)
dont forget to add the action handler
func backButtonHandler(_ sender : UIButton) {
}
try this :
func setupBackButton(){
let backBtn : UIBarButtonItem = UIBarButtonItem(title: "<", style: UIBarButtonItemStyle.plain, target: self, action:#selector(backToPreviousVC))
self.navigationItem.leftBarButtonItem = backBtn
backBtn.tintColor = UIColor.white
}
func backToPreviousVC() {
self.navigationController?.popViewController(animated: true)
}
call setupBackButton() in viewDidLoad
I am trying to set an Image for bar button Item for that I have an image like:
with resolution 30 * 30 but while I assign this Image to Bar button Its looks like:
I have assigned image this way :
and If I try this way like making an IBOutlet for the button and set Image programatically form this question and code for that is:
// Outlet for bar button
#IBOutlet weak var fbButton: UIBarButtonItem!
// Set Image for bar button
var backImg: UIImage = UIImage(named: "fb.png")!
fbButton.setBackgroundImage(backImg, forState: .Normal, barMetrics: .Default)
but nothing happend with this,
Can anybody tell me what I am doing wrong?
or which is the batter way to do this?
I have achieved that programatically with this code:
import UIKit
class ViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
//create a new button
let button: UIButton = UIButton.buttonWithType(UIButtonType.Custom) as! UIButton
//set image for button
button.setImage(UIImage(named: "fb.png"), forState: UIControlState.Normal)
//add function for button
button.addTarget(self, action: "fbButtonPressed", forControlEvents: UIControlEvents.TouchUpInside)
//set frame
button.frame = CGRectMake(0, 0, 53, 31)
let barButton = UIBarButtonItem(customView: button)
//assign button to navigationbar
self.navigationItem.rightBarButtonItem = barButton
}
//This method will call when you press button.
func fbButtonPressed() {
println("Share to fb")
}
}
And result will be:
Same way you can set button for left side too this way:
self.navigationItem.leftBarButtonItem = barButton
And result will be:
And if you want same transaction as navigation controller have when you go back with default back button then you can achieve that with custom back button with this code:
func backButtonPressed(sender:UIButton) {
navigationController?.popViewControllerAnimated(true)

Just choose Original image option when adding an image to assets in Xcode
If your UIBarButtonItem is already allocated like in a storyboard.
(printBtn)
