I am having a weird problem with keeping orientation on the iPad. 在iPad上保持方向时，我遇到了一个奇怪的问题。 Very rarely, when I swap in and out view controllers, my view is displayed as portrait, even though my device is in landscape mode. 很少，当我换入和换出视图控制器时，即使我的设备处于横向模式，我的视图也显示为纵向。

What should I do to resolve this problem? 我应该怎么做才能解决这个问题？ I have already set my controllers to landscape using shouldAutorotateToInterfaceOrientation: method. 我已经使用shouldAutorotateToInterfaceOrientation：方法将控制器设置为横向。 Also, it appears only very rarely, making tracking the bug very difficult. 此外，它很少出现，因此很难跟踪该错误。

Is there a faster way to find out why the orientation is wrong, besides going through each controller? 除了遍历每个控制器之外，还有没有一种更快的方法来找出为什么方向错误？

I see your comment that you are managing orientation by code using "shouldAutorotateToInterfaceOrientation", that is specifically an iOS5 method. 我看到您的评论，说您正在使用“ shouldAutorotateToInterfaceOrientation”（即iOS5方法）通过代码管理方向。 By any chance is the iPad iOS6? iPad iOS6有没有机会？ If it is, you need to back it up with "supportedInterfaceOrientations". 如果是这样，则需要使用“ supportedInterfaceOrientations”进行备份。
