我没有使用故事板。

以上导致class AppDelegate: UIResponder, UIApplicationDelegate { var window: UIWindow? func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool { self.window = UIWindow(frame: UIScreen.mainScreen().bounds) self.window?.backgroundColor = UIColor.whiteColor() self.window?.makeKeyAndVisible() let vc = ViewController() vc.tabBarItem = UITabBarItem(...) ... let tabbar = UITabBarController() tabbar.setViewControllers([...,vc,...], animated: false) self.window?.rootViewController = tabbar tabbar.selectedIndex = 2 return true } } class ViewController: UIViewController { override func loadView() { super.loadView() self.view.backgroundColor = UIColor.yellowColor() //self.automaticallyAdjustsScrollViewInsets = false; } override func viewDidLoad() { super.viewDidLoad() } override func viewDidAppear(animated: Bool) { super.viewDidAppear(animated) } }视图延伸到标签栏下方。我怎么能阻止这个？

我已尝试将观看框架设置为

ViewControllers

但这没效果。

Answer 1

您可以使用edgesForExtendedLayout的{{1}}属性设置要在导航栏下扩展的边缘。如果你不想要，你可以简单地说：

UIViewController

Answer 2

Swift 5 或更高版本

self.edgesForExtendedLayout = []

标签栏下方的Swift View Layout
