Automatic removal of NSNotificationCenter or KVO observers

Read Original

This technical iOS development article details a method to automatically unregister observers for NSNotificationCenter and Key-Value Observing (KVO) to prevent crashes from forgotten removals. It explains implementing categories that use method swizzling in +(void)load, associated objects for data storage, and a deallocation hook to safely clean up observers without requiring changes to existing app code.
