我有一个带有xib文件的viewController B类，我将这个viewController添加到父视图中我的孩子中有一个控制器。
[Acontroller addChildViewController:self]; // self is B
[Acontroller.view addSubview:self.view];
我想要的是，当显示B viewController时，隐藏应用程序的状态栏。
如果我在A控制器中使用：
-(BOOL)preferStatusBarHidden {
return YES;
}
状态栏已隐藏，但我只想从B控制器执行此操作，但它无效。
我该怎么办？
感谢。

您的视图控制器充当自定义容器视图控制器，它封装底层视图控制器。
A是B视图控制器的自定义容器。由于我们正在添加孩子，我们将告诉容器从哪里知道是否显示或隐藏状态栏。
因此，对于自定义容器，我们需要覆盖方法childViewControllerForStatusBarHidden。对于调用prefersStatusBarHidden的视图控制器来确定状态栏可见性的状态，此方法会检测容器。
答案 1 :(得分：0)
试试这个，
保持BOOL检查是否显示B viewController。并在preferStatusBarHidden
- (BOOL)prefersStatusBarHidden {
if (bDisplayed) {
return YES;
}
return NO;
}
并添加B viewController
bDisplayed = YES;
if ([self respondsToSelector:@selector(setNeedsStatusBarAppearanceUpdate)])
{
// if iOS 7
[self prefersStatusBarHidden];
[self performSelector:@selector(setNeedsStatusBarAppearanceUpdate)];
} else {
// if iOS 6
[[UIApplication sharedApplication] setStatusBarHidden:YES withAnimation:UIStatusBarAnimationSlide];
}
答案 2 :(得分：0)
在ViewController A的DidLoad（）方法中写下面的行（你要在哪里显示状态栏）
[[UIApplication sharedApplication] setStatusBarHidden:NO];
在ViewController B的DidLoad（）方法中写下面的行（你不想显示状态栏）
[[UIApplication sharedApplication] setStatusBarHidden:YES];
在appDelegate.m文件中添加以下代码
- (BOOL)prefersStatusBarHidden {
return YES;
}
答案 3 :(得分：0)
如果我把它放在父视图控制器中，状态栏将被隐藏：
-(BOOL)preferStatusBarHidden {
return YES ;
}
但是还需要在子视图控制器中执行此操作，并且不在子视图中调用代码
