所有人都试图用Xcode 8.2和swift 3隐藏状态栏。但是我无法隐藏它。

以及

Answer 1

您可以通过两种方式解决此问题

  

选项1 。在private HttpServletRequest request; private static ThreadLocal<WebContext> wcHolder = new ThreadLocal<WebContext>(); private WebContext(){} public static WebContext newInstance(HttpServletRequest request){ //case 1:correct // WebContext wc = new WebContext(); // wc.request = request; //case 2：incorrect //（to resolve multiply creat WebContext object within one request） WebContext wc = wcHolder.get(); if(wc==null){ wc = new WebContext(); wc.request = request; wcHolder.set(wc); } return wc; } 方法

中尝试此操作

didFinishLaunchingWithOptions

  

选项2 。覆盖func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool { UIApplication.shared.isStatusBarHidden = true return true }

中的prefersStatusBarHidden功能

UIViewController

注意：您致电override var prefersStatusBarHidden : Bool { return true } 它应为override func prefersStatusBarHidden

Answer 2

在swift 3中使用它，

override var prefersStatusBarHidden: Bool {  
    return true  
}

Answer 3

在视图控制器中覆盖prefersStatusBarHidden

override var prefersStatusBarHidden : Bool {
        return true
    }

如果状态栏应该隐藏，则为true;如果应显示状态栏，则为false。
