Swift 3 如何锁定方向

Question

我试图将我的 viewController 锁定为纵向，而不必依赖部署信息，但我的以下代码不起作用

override var shouldAutorotate: Bool {
    return false
}

override var supportedInterfaceOrientations: UIInterfaceOrientationMask {
    return UIInterfaceOrientationMask.portrait
}

 override var preferredInterfaceOrientationForPresentation: UIInterfaceOrientation {
    return UIInterfaceOrientation.portrait
}

override func viewDidLoad() {
    super.viewDidLoad()

}

Answer 1

您可以在 AppDelegate 中尝试这个。这将锁定所有 viewController 的方向

func application(_ application: UIApplication, supportedInterfaceOrientationsFor window: UIWindow?) -> UIInterfaceOrientationMask {
    return UIInterfaceOrientationMask(rawValue: UIInterfaceOrientationMask.portrait.rawValue)
}
