我需要释放手势识别器吗？
如果我将手势识别器添加到名为 cell 的表格单元格中，例如：
UILongPressGestureRecognizer *_longPressRecognizer = [[UILongPressGestureRecognizer alloc] initWithTarget:self action:@selector(cellGestureRecognized:)];
_longPressRecognizer.allowableMovement = 20;
_longPressRecognizer.minimumPressDuration = 1.0f;
[cell addGestureRecognizer:_longPressRecognizer];
[_longPressRecognizer release], _longPressRecognizer = nil;
我是否需要在某个时候在此单元格上手动调用 -removeGestureRecognizer:，或者手势识别器是否需要手动调用 -removeGestureRecognizer:当电池不再使用时，将其移除并释放给我吗？
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?

手势识别器被添加到视图的内部 NSMutableArray 中。一旦视图被释放，这个数组就会被释放。因此，不需要手动调用
-removeGestureRecognizer:。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.
