问题描述

我正在将代码从iOS 8升级到iOS9.我的程序中有一个代码段[[UIApplication applicationName] setStatusBarHidden:YES];.

I am upgrading my code from iOS 8 to iOS 9. I have a code snippet in my program[[UIApplication applicationName] setStatusBarHidden:YES];.

我收到警告"iOS 9.0中已弃用setStatusBarHidden，请使用-[UIViewController preferredsStatusBarHidden"".如果我仅将'setStatusBarHidden'替换为'prefersStatusBarHidden'，则会得到'找不到实例方法'.有人可以建议我如何解决这个问题吗?

I am getting the warning "setStatusBarHidden is deprecated in iOS 9.0, Use -[UIViewController prefersStatusBarHidden". If I just replace 'setStatusBarHidden' with 'prefersStatusBarHidden', I get 'instance method not found'.Can someone please suggest me how to solve this problem?

推荐答案

将以下代码添加到视图控制器中.

Add below code to your view controller..

 - (BOOL)prefersStatusBarHidden {

   return NO;
}

注意:

如果您更改此方法的返回值，请调用setNeedsStatusBarAppearanceUpdate方法.
对于childViewController，要指定一个子视图控制器应该控制首选状态栏的隐藏/未隐藏状态，实施childViewControllerForStatusBarHidden方法.

If you change the return value for this method, call thesetNeedsStatusBarAppearanceUpdate method.
For childViewController, To specify that a child view controllershould control preferred status bar hidden/unhidden state, implementthe childViewControllerForStatusBarHidden method.
