I have a UIBarButton in my navigation bar, I set an image (silhouette.png) to it from the storyboard, and I can change that image's tint (color) at will:
if let num2 = Int(s, radix: 16) { //s="00ff00"
flamingoBtn.tintColor = UIColor(netHex:num2) //this btn is an IBoutlet
}
However, at some point I change the original image for another image (icon.png), programmatically, so I don't need to change the tint in this case, so far so good:
if let url = NSURL(string: "http://www.123di.com/CanonSGLens_132.png") {
if let data = NSData(contentsOfURL: url) {
var newImgThumb : UIImage=UIImage(data: data)!
var iconBtn = UIButton(frame: CGRect(x: 0, y: 0, width: 35, height: 35))
iconBtn.setImage(newImgThumb, forState: UIControlState.Normal)
iconBtn.addTarget(self, action: "goToSettings:", forControlEvents: UIControlEvents.TouchUpInside)
var item = UIBarButtonItem(customView: iconBtn)
self.navigationItem.leftBarButtonItem = item
print("CUSTOM ICON: DOWNLOADED")
}
}
The problem comes, when I switch to the icon image to the original silhouette.png, because I cannot modify the tint any longer, it remains always blue silhoute (default color), instead of green, red, etc:
var newImgThumb : UIImage=UIImage(named: "happyface.png")!
var replyBtn = UIButton(frame: CGRect(x: 0, y: 0, width: 35, height: 35))
replyBtn.setImage(newImgThumb, forState: UIControlState.Normal)
replyBtn.addTarget(self, action: "goToSettings:", forControlEvents: UIControlEvents.TouchUpInside)
replyBtn.tintColor = UIColor.greenColor()
var item = UIBarButtonItem(customView: replyBtn)
item.tintColor = UIColor.greenColor()//UIColor(netHex:num2)
self.navigationItem.leftBarButtonItem = item
What am I doing wrong, why are tint changes igonred afterwards??
If you need extra details let me know.
If you google how to set the custom image for your bar button, pretty much everyone will tell you create a UIButton and then create the UIBarButtonItem from the UIButton as a customView:. In which case, you are doing the right thing here.
However, if you create the UIBarButtonItem via cutomView:, you are not able to change the tintColor any more. And this following is how you set custom image and also changing the tintColor
let item = UIBarButtonItem.init(image: UIImage(named: "happyface.png")!,
style: .Plain,
target: self,
action: Selector("goToSettings:"))
item.tintColor = UIColor.greenColor()
self.navigationItem.leftBarButtonItem = item
Depending where are you calling the code above, you might need to put it inside this structure, to make it run in the UI thread and make the change visible:
dispatch_async(dispatch_get_main_queue()) {
//code here
}
In case someone is still looking for the solution.
barButtonItem.setTitleTextAttributes([NSAttributedString.Key.foregroundColor: UIColor.red], for: .normal)
By setting the NSAttributedString.Key.foregroundColor of the title text attributes, you can set the color of the button.
If you follow this way you can do whatever you need.
let logoutNavBarButtonItem = UIBarButtonItem.init(
image: imageName,
style: .plain,
target: self,
action: #selector(buttonPressed))
navigationItem.leftBarButtonItem = logoutNavBarButtonItem

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")
In my app, I have a custom icon for going back to previous ViewController.
It was working perfectly, but with iOS 13, the icon is misplaced.
The fun fact is that I still have to click on the left (where the back icon used to be, and in other words, on the blank space) to go back to previous ViewController.
Do you have any idea why?
Here is the code I use to customize the back button.
var back = UIImage(named: "backButton")
back = back?.withAlignmentRectInsets(UIEdgeInsetsMake(0, -50, 0, 50))
self.navigationController?.navigationBar.backIndicatorImage = back?.withAlignmentRectInsets(UIEdgeInsetsMake(0, -50, 0, 50))
self.navigationController?.navigationBar.backIndicatorTransitionMaskImage = back?.withAlignmentRectInsets(UIEdgeInsetsMake(0, -50, 0, 50))
self.navigationController?.navigationBar.backItem?.backBarButtonItem = UIBarButtonItem(title: " ", style: UIBarButtonItemStyle.plain, target: nil, action: nil)
self.navigationController?.navigationBar.tintColor = .black
And this is a screenshot of the back icon, not on the left anymore:
Using UIBarButtonItem with customView suits well to your situation. By creating an instance of UIButton gives you command over choosing image and title both, besides custom selector can also be passed to handle button events.
Here is sample code:
let button = UIButton(type: .system)
button.setImage(UIImage(named: "YOUR IMAGE NAME"), for: .normal)
button.setTitle("TITLE IF ANY", for: .normal)
button.sizeToFit()
button.addTarget(self, action: #selector(backBtnPressed(sender:)), for: .touchUpInside)
let leftBtn = UIBarButtonItem(customView: button)
leftBtn.style = .plain
navigationItem.leftBarButtonItem = leftBtn
#objc func backBtnPressed(sender: UIBarButtonItem) {
print("BackBtnPressed")
}
I've been trying to put a hamburger button (the three parallel lines) to the right of the titleView in the nav bar, but every time I do, the image I put in covers the entire nav bar and gets rid of the image I have in titleView.
If I select a default image in the storyboard editor it will appear on the right side of the nav bar without any problems, but as soon as I select the hamburger button in the storyboard editor I get the same problem as before. I've tried with multiple different images and I've changed up the code a little bit with no success. Is there a way to resize the image I'm using so it will fit in the nav bar properly or is there just something wrong with my code?
Here is my code from viewController.swift below:
override func viewDidAppear(_ animated: Bool) {
let nav = self.navigationController?.navigationBar
let imageView = UIImageView(frame: CGRect(x: 0, y: 0, width: 40, height: 40))
imageView.contentMode = .scaleAspectFit
let titleImage = UIImage(named: "logowhitecircle")
imageView.image = titleImage
navigationItem.titleView = imageView
let menuButton = UIButton(frame: CGRect(x: 0, y: 0, width: 40, height: 40))
menuButton.contentMode = .scaleAspectFit
let menuImage = UIImage(named: "hamburgericon")
menuButton.setImage(menuImage, for: .normal)
self.navigationItem.rightBarButtonItem = UIBarButtonItem(customView: menuButton)
You need to set image size in the image assets like 3x = 84px, 2x=56px, 1x = 28px,
see the apple document for more info: https://developer.apple.com/design/human-interface-guidelines/ios/icons-and-images/custom-icons/
let menuButton = UIBarButtonItem(image: UIImage(named: "logowhitecircle"), style: .plain, target: self, action: #selector(menuButtonTapped(_:)))
self.navigationItem.rightBarButtonItem = menuBu
tton
Try Using below code:
let imageBurger = UIImage(named: "hamburgericon")!
let btnLeftMenu = UIButton(type: .system)
btnLeftMenu.bounds = CGRect(x: 10, y: 0, width: imageBurger.size.width, height: imageBurger.size.height)
btnLeftMenu.contentEdgeInsets = UIEdgeInsets(top: 0, left: 0, bottom: 0, right: 0)
btnLeftMenu.setImage(imageBurger, for: UIControl.State())
btnLeftMenu.setTitle(title, for: .normal)
let leftButton = UIBarButtonItem(customView: btnLeftMenu)
self.navigationItem.leftBarButtonItem = leftButton
Try this module FFBadgedBarButtonItem it's easy to use module, here is the documenataion Link
Below is my code how to implement it!
let image = UIImage(named: "yourImage")
let finalImage = resizeImage(image: image!, newWidth: 30)
navigationItem.rightBarButtonItem = FFBadgedBarButtonItem(image: finalImage, target: self, action: #selector(rightButtonTouched))
And here is the calling function
#objc func rightButtonTouched() {
// what event you need to perfom by clicking on this button
}
You need to create Bridging Header to work with this Obj-C module.

Try this:
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: "hamburgericon"), forState: UIControlState.Normal)
//add function for button
button.addTarget(self, action: "customButtonPressed", forControlEvents: UIControlEvents.TouchUpInside)
//set frame
button.frame = CGRectMake(0, 0, 40, 40)
let barButton = UIBarButtonItem(customView: button)
//assign button to navigationbar
self.navigationItem.rightBarButtonItem = barButton
}
//This method will call when you press button.
func customButtonPressed() {
println("button pressed")

I have two buttons on my right of my navigation bar.
extension UIViewController {
func setNavigationBarItem() {
let profileButton = UIBarButtonItem(title: "?", style: .plain, target: self, action: #selector(didTapProfileButton(_:)))
navigationItem.rightBarButtonItems = [addRightBarButtonWithImage(UIImage(named: "menu")!), profileButton]
self.slideMenuController()?.removeRightGestures()
self.slideMenuController()?.addRightGestures()
}
}
I have created 2 buttons like this. But the profileButton I want is with background colour and having corner radius to that button. How to add it to make it look like :
Ignore black part. UIBarButton will be of yellow colour background and corner radius.
For that you have only one option you need to create UIButton instance with design that you want after that create UIBarButtonItem instance from that button.
let btnProfile = UIButton(frame: CGRect(x: 0, y: 0, width: 25, height: 25))
btnProfile.setTitle("SY", for: .normal)
btnProfile.backgroundColor = UIColor.yellow
btnProfile.layer.cornerRadius = 4.0
btnProfile.layer.masksToBounds = true
Now create the UIBarButtonItem from that button and set it with the rightBarButtonItems.
navigationItem.rightBarButtonItems = [addRightBarButtonWithImage(UIImage(named: "menu")!), UIBarButtonItem(customView: btnProfile)]
let profileButton = UIButton()
profileButton.frame = CGRect(x:0, y:0, width:30, height:30)
profileButton.setTitle("SY", for: .normal)
profileButton.setTitle("SY", for: .highlighted)
profileButton.backgroundColor = UIColor.yellow
profileButton.layer.cornerRadius = 5.0
profileButton.addTarget(self, action: #selector(didTapProfileButton(_:)), for: .touchUpInside)
let rightBarButton = UIBarButtonItem(customView: profileButton)
self.navigationItem.rightBarButtonItem = rightBarButton

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")
