C# 在iOS7中如何防止视图在屏幕外显示？

我们正在更新我们的应用程序以与iOS7配合使用，并且在方向和视图放置方面遇到了很多问题

我们使用的视图显示从

类别->位置->位置信息

位置和位置信息视图上有一个返回按钮，可转到上一屏幕。然而，只要按下后退按钮，视图就会在屏幕外的某个位置居中。我之所以知道这一点，是因为在iPhone上运行时，我使用了revealapp应用程序（revealapp.com）来查看视图的位置

当视图在屏幕上正确定位时，其容器视图中心设置为（X:160，Y:240）

但当我按下后退按钮时，视图位于相对的角落，容器视图坐标现在设置为（X:160，Y:720）

你知道这是什么原因吗

我们的UI需要在横向模式下工作，在iOS7升级时，我们在保持这种方向方面遇到了各种各样的问题

任何帮助或线索都将不胜感激

我包括了控制方向的脚本

显示一些代码将使人们更容易帮助您。您是在摆弄视图的框架，还是可能有一些自动布局约束错误？我添加了我认为可以控制方向的代码。我希望这会有帮助。卡梅隆，我会调查一下汽车的布局。
