我想删除屏幕顶部的状态栏。
这不起作用:
func application (application: UIApplication, didFinishLaunchingWithOptions launchOptions: NSDictionary?) -> Bool { application.statusBarHidden = true return true }
我也尝试过:
func application (application: UIApplication, didFinishLaunchingWithOptions launchOptions: NSDictionary?) -> Bool { self.window = UIWindow(frame: UIScreen.mainScreen().bounds) var controller = UIViewController() application.statusBarHidden = true controller.setNeedsStatusBarAppearanceUpdate() var view = UIView(frame: CGRectMake(0, 0, 320, 568)) view.backgroundColor = UIColor.redColor() controller.view = view var label = UILabel(frame: CGRectMake(0, 0, 200, 21)) label.center = CGPointMake(160, 284) label.textAlignment = NSTextAlignment.Center label.text = "Hello World" controller.view.addSubview(label) self.window!.rootViewController = controller self.window!.makeKeyAndVisible() return true }
您确实应该在视图控制器上实现preferredsStatusBarHidden:
Swift 3及更高版本
override var prefersStatusBarHidden: Bool { return true }
