How to hide a status bar in iOS?

提问by Arkady

I can hide a status bar in my app:

我可以在我的应用中隐藏状态栏：

- (void)viewDidLoad{
    [[UIApplication sharedApplication] setStatusBarHidden:YES];
    [super viewDidLoad];
    }

When I chose my launch image and start it first time, it's status bar over a picture. How can I hide this?

当我选择我的启动图像并第一次启动它时，它是图片上方的状态栏。我怎样才能隐藏这个？

You need to add this code in your AppDelegate file, not in your Root View Controller

您需要将此代码添加到您的 AppDelegate 文件中，而不是在您的根视图控制器中

Or add the property Status bar is initially hiddenin your plist file

或者添加属性状态栏最初隐藏在您的 plist 文件中

Folks, in iOS 7+

Use this code either in one or all your view controllers

在一个或所有视图控制器中使用此代码

override var prefersStatusBarHidden: Bool { return true }

覆盖 var prefersStatusBarHidden: Bool { return true }

Add the following code to your view controller:

将以下代码添加到您的视图控制器：

if ([self respondsToSelector:@selector(setNeedsStatusBarAppearanceUpdate)]) {
    // iOS 7
    [self performSelector:@selector(setNeedsStatusBarAppearanceUpdate)];
} else {
    // iOS 6
    [[UIApplication sharedApplication] setStatusBarHidden:YES withAnimation:UIStatusBarAnimationSlide];
}

- (BOOL)prefersStatusBarHidden {
    return YES;
}

What helped me is this (changing plist file):

对我有帮助的是这个（更改 plist 文件）：

1. set Status bar is initially hidden = YES
2. add row: View controller-based status bar appearance = NO

1. 设置状态栏最初是隐藏的 = YES
2. 添加行：查看基于控制器的状态栏外观 = NO

Put this code to your view controller in which you hide status bar:

将此代码放在隐藏状态栏的视图控制器中：

- (BOOL)prefersStatusBarHidden {return YES;}

In iOS 7 status bar appearance depends on UIViewControlleras default. To hide status bar globally, in info.plistuse NOvalue for UIViewControllerBasedStatusBarAppearancekey and use UIApplication's setStatusBarHiddenmethod with YESBOOLvalue.

在 iOS 7 状态栏外观取决于UIViewController默认。全局隐藏状态栏，info.plist使用key 的NOvalueUIViewControllerBasedStatusBarAppearance并使用valueUIApplication的setStatusBarHidden方法YESBOOL。

add this key key from dropdownlist in "info.plist" and voila you will no more see top bar that includes elements something like GSM,wifi icon etc.

从“info.plist”的下拉列表中添加这个键，瞧，您将不会再看到包含GSM、wifi图标等元素的顶部栏。

A complete solution in swift, in your view controller

快速的完整解决方案，在您的视图控制器中

// you can use your own logic to determine if you need to hide status bar
// I just put a var here for now
var hideStatusBar = false
override func preferStatusBarHidden() -> Bool {
    return hideStatus
}


// in other method to manually toggle status bar
func updateUI() {
    hideStatusBar = true
    // call this method to update status bar
    prefersStatusBarHidden()
}
