UIView是否保留其视图控制器 [英] Does a UIView retain its view controller

问题描述

UIView是否保留了它的关联视图控制器？

Does a UIView retain it's associated view controller?

例如，在以下代码中，视图由父视图保留。如果这个视图也保留了它的ViewController，所以我可以在loadView方法中释放控制器。

For example, in the following code the view is retained by the parent view. It would be handy if this view also retained its ViewController so that I could go ahead and release the controller in the loadView method.

- (void) loadView {

  ...

  MyViewController* ctrl = [[MyViewController alloc] init];
  [self.view addSubview: ctrl.view];
  [ctrl release];

}

另外，我想是要跟踪控制器作为实例变量，并在适当时释放它。

The alternative, I suppose, is to keep track of the controller as an instance variable and release it when appropriate.

感谢
