View Controller在发布后收到一条消息，导致崩溃
我有一个设置，我提出了一个UIPickerViewController（模态），然后一些更多的控制器被推上堆栈进行图像编辑。 如果我点击后退button并进入根视图控制器，然后点击另一个选项卡，应用程序崩溃。
这是崩溃消息：
-[PostPhotoViewController respondsToSelector:]: message sent to deallocated instance 0x19b16a60 我运行僵尸工具，它看起来像堆栈上的最后一个视图控制器（PostPhotoViewController）获取消息发送到它，即使它已被释放。 iOS5和iOS6都出现这种情况，所以我没有做任何手动释放/保留。
我已经设置所有的零售点无PostPhotoVC并退订所有通知。 该消息似乎来自标签栏控制器。
不知道如何阻止它，有什么想法？
这里的僵尸读数：

由于某种原因PostPhotoViewController被设置为UITabBarController委托。 删除那些固定的东西。
