I am trying to left align back button i.e remove the space on the left of the back arrow . Using a custom back button .
let backButton = UIBarButtonItem(image: UIImage(named: "arrow03"), style: .Plain, target: self, action: "back")
self.navigationController?.navigationBar.tintColor = UIColor.clearColor()
self.navigationItem.backBarButtonItem = backButton
Tried to use negative width for the button as suggested in the below SO link but it didnt work.

Please help.
Refer below code to implement back button on left alignment.
let button: UIButton = UIButton (type: UIButtonType.Custom)
button.setImage(UIImage(named: "imageName"), forState: UIControlState.Normal)
button.addTarget(self, action: "backButtonPressed:", forControlEvents: UIControlEvents.TouchUpInside)
button.frame = CGRectMake(0, 0, 30, 30)
let barButton = UIBarButtonItem(customView: button)
self.navigationItem.leftBarButtonItem = barButton
Note - Make sure your image has to be plain ( transparent ) background.
func backButtonPressed(btn : UIButton) {
self.navigationController?.popViewControllerAnimated(true)
}
Swift 4 Code
override func viewDidLoad() {
super.viewDidLoad()
let button: UIButton = UIButton (type: UIButtonType.custom)
button.setImage(UIImage(named: "imageName"), for: UIControlState.normal)
button.addTarget(self, action: Selector(("backButtonPressed:")), for: UIControlEvents.touchUpInside)
button.frame = CGRect(x: 0 , y: 0, width: 30, height: 30)
let barButton = UIBarButtonItem(customView: button)
self.navigationItem.leftBarButtonItem = barButton
}
func backButtonPressed(btn : UIButton) {
self.navigationController?.popViewController(animated: true)
}
I'm trying to add a badge to my UIBarButtonItem and for that I have found a this github :
MIBadgeButton-Swift
but I don't know how to use it.
This is my code which makes my custom UIBarButtonItem:
let shopingCartBTN = UIButton(type: UIButtonType.Custom)
shopingCartBTN.setImage(UIImage(named: "shopingCarBarIcon"), forState: UIControlState.Normal)
shopingCartBTN.imageView?.image = UIImage(named: "shopingCarBarIcon")
shopingCartBTN.frame = CGRectMake(0, 0, 60, 30)//Just increase the width of button
shopingCartBTN.setTitle("5", forState: .Normal)
shopingCartBTN.addTarget(self, action: "", forControlEvents: UIControlEvents.TouchUpInside)
let customBarItem = UIBarButtonItem(customView: shopingCartBTN)
self.navigationItem.leftBarButtonItem = customBarItem;
How could I use the MIBadgeButton-Swift to make a badge for my UIBarButtonItem?
Here is two example with custom view and from storyboard
From storyboard by setting custom class :
CODE
#IBOutlet var btnRightBadge: MIBadgeButton!
override func viewDidLoad() {
super.viewDidLoad()
//Custom
let badgeButton : MIBadgeButton = MIBadgeButton(frame: CGRectMake(0, 0, 40, 40))
badgeButton.setTitle("T1", forState: UIControlState.Normal)
badgeButton.setTitleColor(UIColor.blackColor(), forState: UIControlState.Normal)
badgeButton.badgeString = "1";
let barButton : UIBarButtonItem = UIBarButtonItem(customView: badgeButton)
self.navigationItem.leftBarButtonItem = barButton
//From Storyboard
btnRightBadge.badgeString = "5"
}
OUTPUT
You can also use ENMBadgedBarButtonItem-Swift
Try this once.
//Property
var cartBarbuttonItem:MIBadgeButton?
self.cartBarbuttonItem = MIBadgeButton(frame: CGRectMake(40, 5, 40, 44))
self.cartBarbuttonItem?.initWithFrame(frame: CGRectMake(40, 5, 40, 44), withBadgeString: "0", withBadgeInsets: UIEdgeInsetsMake(15, 2, 0, 15))
self.cartBarbuttonItem?.setImage(UIImage(named: "test"), forState: .Normal)
self.cartBarbuttonItem?.setImage(UIImage(named: "test"), forState: .Selected)
self.cartBarbuttonItem?.addTarget(self, action: Selector("loadCart"), forControlEvents: UIControlEvents.TouchUpInside)
self.navigationItem.setLeftBarButtonItem = self.cartBarbuttonItem
I'm creating a custom button item for my navigation bar, and I want it to have the same effect as the button system item ( Slow fade out )
Here is my code :
var button_user : UIImage = UIImage(named:"user.png")!
let button: UIButton = UIButton.buttonWithType(UIButtonType.Custom) as! UIButton
button.setImage(UIImage(named: "user.png"), forState: UIControlState.Normal)
button.setImage(UIImage(named: "user_clicked.png"), forState: UIControlState.Highlighted)
button.addTarget(self, action: nil, forControlEvents: UIControlEvents.TouchUpInside)
button.frame = CGRectMake(0, 0, 28, 30)
let barButton = UIBarButtonItem(customView: button)
self.navigationItem.rightBarButtonItem = barButton
You should change UIButtonType.Custom to UIButtonType.System for that:
let button = UIButton(type: UIButtonType.System)
button.setImage(UIImage(named: "user.png"), forState: UIControlState.Normal)
button.setImage(UIImage(named: "user_clicked.png"), forState: UIControlState.Highlighted)
button.addTarget(self, action: nil, forControlEvents: UIControlEvents.TouchUpInside)
button.frame = CGRectMake(0, 0, 28, 30)
let barButton = UIBarButtonItem(customView: button)
self.navigationItem.rightBarButtonItem = barButton
Edit
Updated for Swift 2.0
button.addTarget(self, action: "buttonClicked:", forControlEvents: UIControlEvents.TouchUpInside)
func buttonClicked(sender:UIButton)
{
dispatch_async(dispatch_get_main_queue(), {
if isHighLighted == false{
sender.highlighted = true;
isHighLighted = true
}else{
sender.highlighted = false;
isHighLighted = false
}
});
}
OR
button.setShowsTouchWhenHighlighted(true)
Edit: You should use UIBarButtonItem instead of UIButton in the navigation bar. That will do.
self.navigationItem.rightBarButtonItem = UIBarButtonItem(image: UIImage(named: "backbutton"), style: UIBarButtonItemStyle.Plain, target: self, action: "buttonClicked:")
And also add the method
func buttonClicked(sender: AnyObject){
//Enter your code here
}
add more "images" for the UIControlState accordingly
I've got this transparent Navigation bar, and I can add a custom icon (code below). However it does not seem to respond to clicks, anyone have any idea why this could be caused?
I'm adding this inside a UIViewController which is inside a UINavigationController.
var button: UIButton = UIButton()
button.setImage(UIImage(named: "customBack"), forState: .Normal)
button.frame = CGRectMake(0, 0, 40, 40)
button.imageEdgeInsets = UIEdgeInsets(top: 10, left: 10, bottom: 10, right: 10)
button.targetForAction("doAction:", withSender: button)
button.backgroundColor = UIColor.brownColor()
var leftItem:UIBarButtonItem = UIBarButtonItem()
leftItem.customView = button
self.navigationItem.leftBarButtonItem = leftItem
self.navigationItem.leftBarButtonItem!.action = "doAction:"
self.navigationController!.navigationItem.leftBarButtonItem = leftItem
I know I shouldn't be adding back items myself but in this exact case it is needed. The icon is added on the fly not before loading the view or w/e.
To try it...
var ysBackButton:UIButton = UIButton(frame:CGRectMake(0, 0, kNavBtnSize, kNavBtnSize))
ysBackButton.setImage(UIImage(named: kBack), forState: UIControlState.Normal)
ysBackButton.addTarget(self, action: Selector("backButtonAction"), forControlEvents:UIControlEvents.TouchUpInside)
var leftBarButton:UIBarButtonItem = UIBarButtonItem(customView: ysBackButton)
self.navigationItem.leftBarButtonItem = leftBarButton
Always just after posting I find out:
I was using
button.targetForAction("doAction:", withSender: button)
Whilst I should be doing:
button.addTarget(self, action: "doAction:", forControlEvents: .TouchUpInside)
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")
