Receive tap gestures only on part of a view

Question

I have a UIImageView in a view controller. Is it possible to make certain areas of the image view tappable?

Example : I have an image of a map. Make only the POIs tappable. Not the whole image. Is this possible?

Answer 1

You can use the handleGesture method. First you need to create a location to receive the touches and you have to compare it with touch location in the delegate method as below:

CGRect locationRect;

in viewdidload

locationRect = CGRectMake(CREATE A FRAME HERE);

next the delegate method

- (void)handleGesture:(UIGestureRecognizer *)gestureRecognizer {
    CGPoint p = [gestureRecognizer locationInView:self.view];
    if (CGRectContainsPoint(locationRect, p)) {
        NSLog(@"it's inside");
    } else {
        NSLog(@"it's outside");
    }
}
