iphone - How to test if a point is in a view

Question

I have a UIImageView and I have a CGPoint on the screen. I want to be able to test that point to see if it is in the UIImageView. What would be the best way to do this?

Answer 1

CGPoint is no good with a reference point. If your point is in window's coordinates then you can get it using

CGPoint locationInView = [imageView convertPoint:point fromView:imageView.window];
if ( CGRectContainsPoint(imageView.bounds, locationInView) ) {
    // Point lies inside the bounds.
}

You may also call pointInside:withEvent: method

if ( [imageView pointInside:locationInView withEvent:nil] ) {
    // Point lies inside the bounds
}
