Do I need to release a gesture recognizer?

Question

If I add a gesture recognizer to a table cell called cell, e.g.:

UILongPressGestureRecognizer *_longPressRecognizer = [[UILongPressGestureRecognizer alloc] initWithTarget:self action:@selector(cellGestureRecognized:)]; _longPressRecognizer.allowableMovement = 20; _longPressRecognizer.minimumPressDuration = 1.0f; [cell addGestureRecognizer:_longPressRecognizer]; [_longPressRecognizer release], _longPressRecognizer = nil;  

Do I need to manually call -removeGestureRecognizer: on this cell at some point, or does the gesture recognizer get removed and released for me when the cell is no longer used?

Answer 1

The gesture recognizers are added to an internal NSMutableArray of the view. This array will be released once the view is deallocated. Thus -removeGestureRecognizer: doesn't need to be called manually.
