How I get the tag value from the sender

Question

- (IBAction)onClick1:(id)sender {
    // Make sure it's a UIButton
    if (![sender isKindOfClass:[UIButton class]])
        return;

    NSString *title = [(UIButton *)sender currentTitle];
}

I understand how to get the title and other current values but I don't see how I can get the value of the tag property.

Answer 1

I've got a test project here where I just used:

NSInteger i = [sender tag];

Answer 2

You can simply call:

NSInteger the_tag = ((UIView*)sender).tag;

Each UIButton is a subclass of UIView which contains the tag property.
