LongPressGestureRecognizer problems

[pete42]

I created calendar view with buttons and i am trying to use long press to implement local notifiactions. For example, the user taps on the btn for 2 seconds, a uialertview pops up and asks to set notification.

my problem is with the first part. I need a way to identify which gesture recognizer is tapped. I know how to do this with tags for buttons but I can't seem to figure out how it works with gesture recongizers.

my buttons and gesture recognizers are dynamically created and assigned.

If anyone has figured it out your help would be greatly appreciated.

here is an image of the view to give you an idea. the red and blue squares are buttons.

I'd like to know how to code the long press of a button; the tap vs the 2-sec press.

UILongPressGestureRecognizer *longPressGR;
UIButton *btn;

	UIGestureRecognizer *recognizer;
		recognizer = [[ UILongPressGestureRecognizer alloc] initWithTarget:self action:@selector(handleLongPress:)];
		recognizer.delegate = self;
		
		longPressGR = (UILongPressGestureRecognizer *)recognizer;
		longPressGR.minimumPressDuration = 2.0;
				
		[btn addGestureRecognizer:longPressGR];

-(void) handleLongPress:(UILongPressGestureRecognizer *)recognizer  {
   //do stuff here
}

The Buttons's action doesn't get called. I use touchUpInside so it works. It might not work with touchDown. Just try it you'll see that it works.

If you would know how to differentiation recognizers with tags or something, that would be great.
