Question

Is there a way to cancel a touch for a UIButton? I envision it as something like:

- (BOOL)shouldProcessTouch {
    return NO;
}

You know, a place where you can run logic and cancel the touch in certain scenarios. Any ideas?

** EDIT **

For those familiar with event based systems, I’m looking for the equivalent of:
event.stopPropagation();

In most cases, a UIButton will call a method when touched. It may look like this:

-(IBAction)submitButtonPressed:(id)sender{

    if(shouldRespond){
       //do things normally
    }
    else{
      return;  //do nothing

    }


}

In this example, shouldRespond is your flag. You should set this flag based on whatever conditions you have.

edit: the flag is a BOOL
