iOS彻底隐藏app状态栏StatusBar的方法汇总

方法一：
整个app中隐藏
1.首先工程的.plist文件中View controller-based status bar appearance这一栏必须设置为YES
2.再修改以下代码

//For Objective-C:

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
  [application setStatusBarHidden:YES];

  return YES;
}
//For Swift:

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject:AnyObject]?) -> Bool {
  application.statusBarHidden = true

  return true
}

方法二：
在单个视图隐藏：
1.首先工程的.plist文件中View controller-based status bar appearance这一栏设置为NO；
Status bar is initially hidden设置为YES。
2.再添加以下代码

//For Objective-C:

- (BOOL)prefersStatusBarHidden {
  return YES;
}
//For Swift:

override func prefersStatusBarHidden() -> Bool {
  return true
}

方法三：
在某一特定方法隐藏：
1.首先工程的.plist文件中View controller-based status bar appearance这一栏必须设置为YES
2.再添加以下代码： 
//For Objective-C:

- (void)HideStataBar{
    if ([self respondsToSelector:@selector(setNeedsStatusBarAppearanceUpdate)]) {
        //调用隐藏方法
        [self prefersStatusBarHidden];
        
        [self performSelector:@selector(setNeedsStatusBarAppearanceUpdate)];
    }
}



//实现隐藏方法
- (BOOL)prefersStatusBarHidden{
    
    return hidestatusbar;
}

//其中hidestatusbar为BOOL型YES或NO，可以在调用方法前自定义。

//For Swift:

func hideStataBar() {
    if responds(to: #selector(self.setNeedsStatusBarAppearanceUpdate)) {
 //调用隐藏方法
        prefersStatusBarHidden
        perform(#selector(self.setNeedsStatusBarAppearanceUpdate))
    }
}

//实现隐藏方法
var prefersStatusBarHidden: Bool {
    return hidestatusbar
}

//method 1:

//Hidden in the whole app:

//Firstly, View controller-based status bar appearance in the .plist file must be set to YES.



//If you want status bar to be hidden in the whole app:

//For Objective-C:



- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {

  [application setStatusBarHidden:YES];



  return YES;

}

//For Swift:



func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject:AnyObject]?) -> Bool {

  application.statusBarHidden = true



  return true

}





//method 2:

//Hidden in Specify View Controller

//If you want status bar is disappeared in Specify View Controller, in .m file, just implement:

//For Objective-C:



- (BOOL)prefersStatusBarHidden {

  return YES;

}

//For Swift:



override func prefersStatusBarHidden() -> Bool {

  return true

}





//method 3:



//Hidden in Specify method:

//Firstly, View controller-based status bar appearance in the .plist file must be set to YES.



//2.add the below code：

//For Objective-C:

- (void)HideStataBar{



    if ([self respondsToSelector:@selector(setNeedsStatusBarAppearanceUpdate)]) {



        //Call the Hidden Method



        [self prefersStatusBarHidden];



        [self performSelector:@selector(setNeedsStatusBarAppearanceUpdate)];



    }



}



//Implement Hidden Method



- (BOOL)prefersStatusBarHidden{



    return hidestatusbar;



}



//the hidestatusbar is a BOOL type YES or NO，you can customize it before you call the Hidden method.



For Swift:



func hideStataBar() {

    if responds(to: #selector(self.setNeedsStatusBarAppearanceUpdate)) {

        //Call the Hidden Method

        prefersStatusBarHidden

        perform(#selector(self.setNeedsStatusBarAppearanceUpdate))

    }

}



//Implement Hidden Method

var prefersStatusBarHidden: Bool {

    return hidestatusbar

}
