Is there an way to make an invisible UIButton that will still “be there” and catch touch events for my UIImageView?

Question

I thought to be clever and just put an transparent UIButton over an UIImageView with the exact frame size, so that I can wire it up easily with any event I like, for example

Answer 1

This is what i did but with using a subclass of UIButton which i later found out should not be subclassed as per the net. My subclass was called Points

Points *mypoint=[Points buttonWithType:UIButtonTypeCustom];

then if you have an image you want to add to the button : [mypoint setImage:imageNamed:@"myimage"] forstate: UIControlStateNormal];

if you dont add this image then the button will be invisible to the user but should respond to touch. Thats how i created a hotspot on my imageView inorder to have it respond to user interaction.
