使用Swift在一个ViewController中强制横向模式 [英] Force landscape mode in one ViewController using Swift

问题描述

我试图在我的应用程序中仅在横向模式下强制使用一个视图，
我正在调用

I am trying to force only one view in my application on landscape mode, I am calling

override func shouldAutorotate() -> Bool {
    print("shouldAutorotate")
    return false
}

override func supportedInterfaceOrientations() -> Int {
    print("supportedInterfaceOrientations")
    return Int(UIInterfaceOrientationMask.LandscapeLeft.rawValue)
}

override func preferredInterfaceOrientationForPresentation() -> UIInterfaceOrientation {
    return UIInterfaceOrientation.LandscapeLeft
}

视图在纵向模式，并在我更改设备方向时保持旋转。

永远不会调用shouldAutorotate。

任何帮助都将受到赞赏。

The view is launched in the portrait mode, and keep rotating when I change the device orientation.
The shouldAutorotate is never called.
Any help would be appreciated.

推荐答案

它可能对其他人有用，我找到了一种强制视图以横向模式启动的方法：

It may be useful for others, I found a way to force the view to launch in landscape mode:

将它放在viewDidLoad（）中：

Put this in the viewDidLoad():

let value = UIInterfaceOrientation.LandscapeLeft.rawValue
UIDevice.currentDevice().setValue(value, forKey: "orientation")

和

override func shouldAutorotate() -> Bool {
    return true
}
