Listen for a UIView's touchesBegan/touchesEnded within an NSObject

So I have an NSObject that accepts a UIView in the init function, and assigns it as a property. The functionality of this behavior class depends on how long the UIView is pressed, using touchesBegan/touchesEnded.

I want to encapsulate this touchesBegan/touchesEnded logic within the NSObject class, in an effort to make this behavior class more modular. Currently, the touchesBegan/touchesEnded functionality is in the UIViewController class, and passed to the behavior.

Is it possible to override and/or "listen" for touchesBegan/Ended in the NSObject class?

For custom touch handling logic you should subclass UIGestureRecognizer. You can then add it to any view.

Check out the documentation for gesture recognizers and the guide.
