横向模式下的SafariViewController

Question

我有一个仅在纵向模式下的ViewController。它呈现了一个SafariViewController。是否可以将SafariViewController的方向更改为Landscape来维护ViewController的Portrait？

Answer 1

这适用于Swift 4.2。您必须在viewController中添加此方法以保持纵向方向

override var supportedInterfaceOrientations:UIInterfaceOrientationMask {
    return UIInterfaceOrientationMask.portrait
}

你也必须申报

let appDelegate = UIApplication.shared.delegate as! AppDelegate

同样在你的AppDelegate中你必须添加

var myOrientation: UIInterfaceOrientationMask = .portrait

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

这时你正在创建SFSafariViewController

let appDelegate = UIApplication.shared.delegate as! AppDelegate
    appDelegate.myOrientation = .all
