self.window无法在视图控制器内部工作

Question

对于iOS 7,我有状态栏问题.为此我通过在Appdelegate中使用以下代码解决了它

if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 7) {
    [[UIApplication sharedApplication] setStatusBarStyle: UIStatusBarStyleLightContent];
    self.window.clipsToBounds =YES;
    self.window.frame =  CGRectMake(0,20,self.window.frame.size.width,self.window.frame.size.height-20);
    self.window.bounds = CGRectMake(0,0, self.window.frame.size.width, self.window.frame.size.height);
}

一切都很完美.

只有它在拍照时才会出问题.

当我打开相机或照片库时,我仍然会看到状态栏,因此我看到了一半导航标题,如下所示.

知道我怎么能克服这个错误？

问题是:

1. 照片库/相机就像上面的图像

2. 如果单击取消,我的视图会自动向上移动20px.

代替:

self.window 

用这个:

[[self view] window]

试试这样:

if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 7) {
    [[UIApplication sharedApplication] setStatusBarStyle: UIStatusBarStyleLightContent];
    self.view.window.clipsToBounds =YES;
    self.view.window.frame =  CGRectMake(0,20,self.view.window.frame.size.width,self.view.window.frame.size.height-20);
    self.view.window.bounds = CGRectMake(0,0, self.view.window.frame.size.width, self.view.window.frame.size.height);
}
