What methods to call for handling events for UIObject?

Is there a pattern Apple follows for which methods to call for handling an event for a UI objects?

What I mean is, to set an action for UIButton is [button addTarget:action:forControlEvents] and for an ImageView I have to [imageView addGestureRecognizer]

I can never remember what methods to call. Is there an easy way to remember?

The "pattern" is that it is normal behavior for a button to respond to control events while it is not very common for an image view to respond to user interaction. Normally if you want to have a tappable image, you would use a UIButton and set an image on it. Apple decided to write the control events into UIButtons but not normal UIViews or UIImageViews.

So basically, you can use a control event if it is a button, otherwise you must use a different method. For normal views, gesture recognizers are a good option.
