Iphone 为什么我的UINavigation控制器关闭了79像素

在iphone中，一切都很好

但是，当我查看导航栏框架时，它是-44？Iphone的y原点是0

应该是这个吗？现在所有的东西似乎都向上移动了79个像素

知道怎么修理吗

当我旋转所有尺寸时，确定的只是初始的横向尺寸是错误的

添加到视图中，这段代码修复了它，但显然不是我想要做的：navigationController.view.superview.frame=CGRectMake（-79，0，size.width，size.height）

应用程序代表：

代码。。。。你看到你的nib文件了吗？nib文件有时表示为4''，其中默认模拟器是3.5''设备，我在interface builder中放置项目时注意到了这一点。。。如果不是这样的话，只需发布一些代码来打印你的导航控制器框架。我正在模拟一台iPad。这只发生在iPad模拟器上
