【问题描述】：

我的 iPhone 应用程序在 iPad 上运行时出现问题。我在第一个屏幕中使用相机覆盖视图（在应用程序启动时启动），但是当我导航到其他屏幕时，它上面有一个空白区域。这会出现仅在 iPad 上，在 iPhone 上都很好用。

这是显示空白屏幕的附加图像

相机覆盖视图代码

    controlView = [[UIView alloc]initWithFrame:CGRectMake(0, 0, 320, 480)];
controlViewLandscape  = [[UIView alloc]initWithFrame:CGRectMake(0, 0, 480, 320)];

【参考方案1】：

这可能是因为状态栏显示在 iPad 的顶部，而它存在于 iPhone 的那个白色位置。

【讨论】：

如果我删除第一个屏幕中使用的相机覆盖视图，并使用简单的视图，那么它在 iphone 和 ipad 上都可以正常工作

如何从相机叠加视图添加第一个屏幕？发布代码

我添加了用于向相机添加叠加视图的代码

【参考方案2】：

解决了，

使用下面一行显示状态栏

[[UIApplication sharedApplication]setStatusBarHidden:NO]; 

它会显示一个黑条而不是一个空白。
