Set Custom Images to the Uibarbuttonitem But It Doesn't Show Any Image

Set custom images to the UIBarButtonItem but it doesn't show any image

Thats because UIBarButtonItem image's default rendering mode always draw the image as a template image, ignoring its color information (UIImageRenderingModeAlwaysTemplate). Just create your image using UIImage's method imageWithRenderingMode always original.

UIImage(named: "yourImageName")!.withRenderingMode(.alwaysOriginal)

Add image to UIBarButtonItem button

UIButton *favButton = [[UIButton alloc] init];

[favButton setImage:[UIImage imageNamed:@"unselected.png"] forState:UIControlStateNormal];
[favButton addTarget:self action:@selector(favouriteButtonClicked:)
   forControlEvents:UIControlEventTouchUpInside];

UIBarButtonItem *button = [[UIBarButtonItem alloc]
                                initWithCustomView:favButton];

self.navigationItem.rightBarButtonItem = button;

[button release];
[favButton release];

iOS: Custom image UIBarButtonItem does not respond to touches

If I remember right, I had this problem with one of my past projects. I believe it is an issue with the UIBarButtonItem. The workaround would be...

UIButton *imageButton = [UIButton buttonWithStyle:UIButtonStyleCustom];
imageButton.frame = CGRectMake(0,0,24,24);//Standard size of a UIBarButtonItem i think.
[imageButton setImage:[UIImage imageNamed:@"arrow_up_24.png"] forState:UIControlStateNormal];
[imageButton addTarget:self action:@selector(logoutButtonPressed) forControlEvents:UIControlEventTouchUpInside];

UIBarButtonItem *barItem = [[UIBarButtonItem alloc] initWithCustomView:imageButton];

//Add it to your bar or whatever here.

If you want the white glow like the regular buttons, you'll have to set

imageButton.showsTouchWhenHighlighted = YES;

iOS 11 UIBarButtonItem images not sizing

BarButtonItem (iOS11\xCode9) uses autolayout instead of frames. Try this (Swift):

if #available(iOS 9.0, *) {
    cButton.widthAnchor.constraint(equalToConstant: customViewButton.width).isActive = true
    cButton.heightAnchor.constraint(equalToConstant: customViewButton.height).isActive = true
}

Objective C

if (@available(iOS 9, *)) {
     [cButton.widthAnchor constraintEqualToConstant: standardButtonSize.width].active = YES;
     [cButton.heightAnchor constraintEqualToConstant: standardButtonSize.height].active = YES;
}

Custom UIBarButtonItems from UIButtons with custom images - is it possible to make the tap targets larger?

Small changes to your code will do the stuff

Changes needed :

• I am assuming that the size of backButtonImage is {28,17} and setting the button frame as CGRectMake(0, 0, 48, 37) `
• remove the backGroundImage and use setImage:
• set the property imageEdgeInsets to UIEdgeInsetsMake(10, 10, 10, 10)

Your code will become like this:

UIButton *backButton = [UIButton buttonWithType:UIButtonTypeCustom];
backButton.frame = CGRectMake(0, 0, 48, 37);
[backButton addTarget:self action:@selector(backButtonTapped) forControlEvents:UIControlEventTouchUpInside];
backButton.showsTouchWhenHighlighted = YES;

UIImage *backButtonImage = [UIImage imageNamed:@"back-button.png"];
[backButton setImage:backButtonImage forState:UIControlStateNormal];

backButton.imageEdgeInsets = UIEdgeInsetsMake(10, 10, 10, 10);

UIBarButtonItem *backBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:backButton];

[toolBarItems addObject:backBarButtonItem];

You can change the value for the frame and the imageEdgeInsets as per your requirements.

This code worked for me.

How to set image for bar button with swift?

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")
    }
}

setting image for UIBarButtonItem - image stretched

The displayed images on bar button items are 'derived' from the source image (it uses only the alpha channel values in rendering but that all looks ok in your image). Its possibly just not the right size - you might need to open the image file and crop it to the right size.

You could also try looking at whether setting the imageInsets property (inherited by UIBarButtonItem from UIBarItem) can be used to adjust the size in a way to stop it getting stretched.

Doco on the bar item images says the following:

The images displayed on the bar are derived from this image. If this image is too large to fit on the bar, it is scaled to fit. Typically, the size of a toolbar and navigation bar image is 20 x 20 points.

toggle custom image in a UIBarButtonItem

I finally figured it out...only took a couple of days but I've been too busy to post up a solution. We'll I finally got time and am happy to post my solution. I had a hunch that this would'nt work unless it was done 100% programmatically, and I was right. Here's the final solution to my problem:

if(mute == YES)
{
    UIImage *image = [UIImage imageNamed:@"audio-off.png"];
    UIButton *myMuteButton = [UIButton buttonWithType:UIButtonTypeCustom];
    myMuteButton.bounds = CGRectMake( 0, 0, image.size.width, image.size.height );    
    [myMuteButton setImage:image forState:UIControlStateNormal];
    [myMuteButton addTarget:self action:@selector(mute) forControlEvents:UIControlEventTouchUpInside];    
    UIBarButtonItem *myMuteBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:myMuteButton];   
    navBar.leftBarButtonItem = myMuteBarButtonItem;
    [myMuteBarButtonItem release];
}
else
{
    UIImage *image = [UIImage imageNamed:@"audio-on.png"];
    UIButton *myUnmuteButton = [UIButton buttonWithType:UIButtonTypeCustom];
    myUnmuteButton.bounds = CGRectMake( 0, 0, image.size.width, image.size.height );    
    [myUnmuteButton setImage:image forState:UIControlStateNormal];
    [myUnmuteButton addTarget:self action:@selector(mute) forControlEvents:UIControlEventTouchUpInside];    
    UIBarButtonItem *myUnmuteBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:myUnmuteButton];
    navBar.leftBarButtonItem = myUnmuteBarButtonItem;
    [myUnmuteBarButtonItem release];
}

the good news is I finally finished my app and submitted it to the app store. Hopefully everything will go smooth and am looking forward to it!
