How to read button tag in IBAction?

Question

I have button:

...

UIButton* rightButton = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
[rightButton setTitle:annotation.title forState:UIControlStateNormal];
rightButton.tag = myCustomNumber;
[rightButton addTarget:self action:@selector(showDetails:) forControlEvents:UIControlEventTouchUpInside];
...

And here is IBAction:

..
-(IBAction)showDetails:(id)sender{

    // here I want to NSLOG button tag

}
...

How to do that?

Answer 1

Just cast your sender to UIControl

-(IBAction)showDetails:(UIControl *)sender {

    // here I want to NSLOG button tag
    NSLog(@"%d",sender.tag);

}
