UIView's methods when it is loaded/visible and unloaded/disappeared

Question

I am building a custom control, in which I want to register control (subclass of UIButton) for notification when it is loaded, and unregister when UIView is unloaded.

I have searched a lot, and found numerous methods for UIViewController's life cycle but not for simple UIView.Can you provide methods when I can determine start and end of UIView

Above link is very detailed for loading part of UIView lifecycle, but it do not addresses unloading or end of it. — Muhammad Nabeel Arif, Aug 25 '14 at 13:07
Also, if you are making a custom control then it might make sense to subclass `UIControl` instead. (this is not an answer to your question, just a comment) — David Rönnqvist, Aug 25 '14 at 13:15

What about registering for notifications when the control is created (with initWithFrame and initWithCoder) and deregistering when the control is destructed (in dealloc). You can then check for self.window at every notification to see if the control is visible.
