leftbarbuttonitem does not show up in the navigation bar

Question

I\'ve been developing an iOS app and have been having issues with using an image as the left bar button item in the navigation bar. I have attempted this in the following wa

Answer 1

Calling myButton.sizeToFit() before assigning to leftBarButtonItem helped me.

    let cancelButton = UIButton()
    cancelButton.backgroundColor = .red
    cancelButton.setTitle("Common/Cancel".localized, for: .normal)
    cancelButton.sizeToFit() //!!!
    let cancelBarButton = UIBarButtonItem(customView: cancelButton)
    navigationItem.leftBarButtonItem = cancelBarButton

Answer 2

Add a Navigation Item to the Views storyboard and create an outlet for it in the ViewController. Then, use your outlet instead of self.navigationController?.navigationItem to reference leftBarButtonItem.

Answer 3

I had the same problem. To see the button, I had to change the tint color, here's the code in Swift:

self.navigationItem.leftBarButtonItem = UIBarButtonItem.init(image:UIImage.init(named: "btn_back_default")!, style:UIBarButtonItemStyle.Plain, target: self, action: Selector("back"))
self.navigationItem.leftBarButtonItem?.tintColor = UIColor.whiteColor()

Answer 4

Replace your code to initialize the button as a customType like this:

UIImage *backButtonImage = [UIImage imageNamed:@"backButtonCB"];
    CGRect buttonFrame = CGRectMake(0, 0, backButtonImage.size.width, backButtonImage.size.height);
    UIButton *backButton = [UIButton buttonWithType:UIButtonTypeCustom];
    [backButton setFrame:buttonFrame];
    [backButton setImage:backButtonImage forState:UIControlStateNormal];
    UIBarButtonItem *backBarButtonItem= [[UIBarButtonItem alloc] initWithCustomView: backButton];
    self.navigationItem.leftBarButtonItem = backBarButtonItem;

Hope it helps....:)

Try to use this code,

self.navigationItem.hidesBackButton=YES;

UIImage *buttonImage = [UIImage imageNamed:@"Back"];
UIButton *aButton = [UIButton buttonWithType:UIButtonTypeCustom];
[aButton setImage:buttonImage forState:UIControlStateNormal];
aButton.frame = CGRectMake(0.0,0.0,buttonImage.size.width,buttonImage.size.height);
[aButton addTarget:self action:@selector(backBtnTapped) forControlEvents:UIControlEventTouchUpInside];
UIBarButtonItem *backButton = [[UIBarButtonItem alloc] initWithCustomView:aButton];
self.navigationItem.leftBarButtonItem = backButton;

Updated for Swift 5:

let image = UIImage(named: "iconClose")
let button = UIBarButtonItem(image: image, style: .plain, target: self, action: #selector(self.cancel))
navigationItem.leftBarButtonItem = button
