Is NSNotificationCenter removeObserver in ARC needed? [duplicate]

Answer 1

You should explicitly remove the observer even you use ARC. Create a dealloc method and remove there..

-(void)dealloc {
    [[NSNotificationCenter defaultCenter] removeObserver:self];
}

If you see the method you don't need to call [super dealloc]; here, only the method without super dealloc needed.

UPDATE for Swift

You can remove observer in deinit method if you are writing code in swift.

deinit {
        NSNotificationCenter.defaultCenter().removeObserver(self)
       }
