How to prevent multiple event on same UIButton in iOS?

Question

I want to prevent continuous multiple clicks on the same UIButton.

I tried with enabled and exclusiveTouch properties but it didn't work. Such as:

-(IBAction) buttonClick:(id)sender{
    button.enabled = false;
    [UIView animateWithDuration:1.0 delay:0.0 options:UIViewAnimationOptionAllowAnimatedContent animations:^{
        // code to execute
     }
     completion:^(BOOL finished){
         // code to execute  
    }];
    button.enabled = true;
}

Answer 1

What you're doing is, you simply setting enabled on/off outside of the block. This is wrong, its executing once this method will call, thus its not disabling the button until completion block would call. Instead you should reenable it once your animation would get complete.

-(IBAction) buttonClick:(id)sender{
    button.enabled = false;
    [UIView animateWithDuration:1.0 delay:0.0 options:UIViewAnimationOptionAllowAnimatedContent animations:^{
        // code to execute
     }
     completion:^(BOOL finished){
         // code to execute  
        button.enabled = true; //This is correct.
    }];
    //button.enabled = true; //This is wrong.
}

Oh and yes, instead of true and false, YES and NO would looks nice. :)
