I add custom button to navigation controller
UIBarButtonItem *backButton = [[UIBarButtonItem alloc] initWithImage:[UIImage imageNamed:@"back.png"]
style:UIBarButtonItemStylePlain
target:self
action:@selector(backAction)];
self.navigationItem.leftBarButtonItem = backButton;
it works fine, but button appears bordered. How can I fix that?
UPDATE
I found solution
UIButton *button = [[UIButton alloc] initWithFrame:CGRectMake(0, 0, 25, 25)];
[button setImage:[UIImage imageNamed:@"back.png"] forState:UIControlStateNormal];
[button addTarget:self action:@selector(buttonFavoriteClicked) forControlEvents:UIControlEventTouchUpInside];
UIBarButtonItem *back = [[UIBarButtonItem alloc] initWithCustomView:button];
[button release];
self.navigationItem.leftBarButtonItem = back;
Try this.
UIButton *backButton = [[UIButton alloc] initWithFrame:CGRectMake(0, 0, button_width, button_height)];
[backButton setImage:[UIImage imageNamed:@"back.png"] forState:UIControlStateNormal];
[backButton addTarget:self action:@selector(backAction) forControlEvents:UIControlEventTouchUpInside];
self.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:backButton];
For Swift 4
let backButton = UIButton(frame: CGRect(x: 0, y: 0, width: 25, height: 25))
backButton.setImage(UIImage(named: "back.png"), for: .normal)
backButton.addTarget(self, action: #selector(backAction), for: .touchUpInside)
self.navigationItem.rightBarButtonItem = UIBarButtonItem(customView: backButton)
And action (selector) should be like the following :
@objc func backAction () {
// do the magic
}
