我是否负责在dealloc中发布UIView的gestureRecognizers？ [英] Am I responsible for releasing a UIView's gestureRecognizers in dealloc?

问题描述

我已将UIGestureRecognizer附加到UIView。在dealloc期间释放这个是谁的责任？

I have attached a UIGestureRecognizer to a UIView. Whose responsibility is it to release this during dealloc?

具体来说：

UITapGestureRecognizer *t = 
[[UITapGestureRecognizer alloc] initWithTarget:self.view action:@selector(tapHandler:)];

[self.view addGestureRecognizer:t];
[t release];

因此，self.view目前只保留gestureRecognizer。

So, self.view currently has sole retention of the gestureRecognizer.

更新
我应该更清楚。我的问题与视图dealloc方法有关。视图发布时，视图的超类是否处理gestureRecognizer的释放。我现在假设是这样的。

Update I should have been clearer. My question has to do with the views dealloc method. Does the view's superclass handle release of the gestureRecognizer when the view is released. I currently assume that is the case.

推荐答案

经验法则是，无论何时打电话，都要拨打发布 alloc ， new 或 copy 。

The rule of thumb is that you call release whenever you call alloc, new or copy.

由于你调用了alloc，你的代码不会过度释放或泄漏任何东西。

Since you called alloc, your code is not over-releasing or leaking anything.

当你可以自动释放你的手势识别器，我会不因为在可能的情况下明确释放对象是更好的内存管理。 （在自动释放池耗尽之前，自动释放的对象不会被释放。）

While you could autorelease your gesture recognizer, I would not because explicitly releasing objects, where possible, is better memory management. (Autoreleased objects don't get released until the autorelease pool is drained.)
