Navigation Bar custom button

Question

backButton =  [UIButton buttonWithType:UIButtonTypeCustom];

[backButton addTarget:self action:@selector(gotoAmphorasViewController) forControlEvents:UIControlEventTouchUpInside];

[backButton setFrame:CGRectMake(0.0f,0.0f, 44,44)];

The problem i am facing is that though the button dimensions are44*44, wherever i tap anywhere around it, the the button action is fired.

Answer 1

Please try the bellow code : its working properly

- (void)viewDidLoad {
    [super viewDidLoad];
UIImage *buttonImage = [UIImage imageNamed:@"back.png"];

    UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];

    [button setImage:buttonImage forState:UIControlStateNormal];


    button.frame = CGRectMake(0, 0, buttonImage.size.width, buttonImage.size.height);

     [button addTarget:self action:@selector(back) forControlEvents:UIControlEventTouchUpInside];

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

    self.navigationItem.leftBarButtonItem = customBarItem;
    [customBarItem release];



}

-(void)back {

[self.navigationController popViewControllerAnimated:YES];
}
