Ios Swift：全屏时以横向模式播放视频

我有以下代码：

import UIKit
import MediaPlayer

class ViewController: UIViewController {
    var moviePlayer:MPMoviePlayerController!
    var bounds: CGRect = UIScreen.mainScreen().bounds

    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.

        var width:CGFloat = bounds.size.width
        var height = (width / 16) * 9

        var url:NSURL = NSURL(string: "http://jplayer.org/video/m4v/Big_Buck_Bunny_Trailer.m4v")
        moviePlayer = MPMoviePlayerController(contentURL: url)
        moviePlayer.view.frame = CGRect(x: 0, y: 40, width: width, height: height)
        self.view.addSubview(moviePlayer.view)
        moviePlayer.fullscreen = true
        moviePlayer.controlStyle = MPMovieControlStyle.Embedded
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }

}

它可以从服务器播放视频，但我有一个问题：

如果我想有肖像模式的应用程序，我仍然可以把它变成风景只有当用户在全屏模式下播放视频？如果是，如何做到这一点

谢谢。是的。当MPMoviePlayercontroller进入全屏模式时，您可以强制更改方向。只需将通知MPMoviePlayerwillerInterfullScreenNotification observer添加到您的ViewDiLoad/ViewWillDisplay中，并按如下方式更改方向

     override func viewDidLoad() {
            super.viewDidLoad()

        NSNotificationCenter.defaultCenter().addObserver(self, selector: "videoMPMoviePlayerWillEnterFullscreen:", name: MPMoviePlayerWillEnterFullscreenNotification, object: nil);
//change orientation to portrait when user exits the full screen


 NSNotificationCenter.defaultCenter().addObserver(self, selector: "videoMPMoviePlayerWillExitFullscreenNotification:", name: MPMoviePlayerWillExitFullscreenNotification, object: nil);

    }

   func  videoMPMoviePlayerWillEnterFullscreen(notification:NSNotification)
    {
        let value = UIInterfaceOrientation.LandscapeLeft.rawValue ;// UIInterfaceOrientation.LandscapeRight.rawValue
        UIDevice.currentDevice().setValue(value, forKey: "orientation")
    }



  func  videoMPMoviePlayerWillExitFullscreenNotification(notification:NSNotification)
    {
        let value = UIInterfaceOrientation.Portrait.rawValue ;// UIInterfaceOrientation.LandscapeRight.rawValue
        UIDevice.currentDevice().setValue(value, forKey: "orientation")
    }

不要忘记移除观察者

应用程序委托可以实现application:supportedInterfaceOrientionsforWindow:以返回UIInterfaceOrientationTask，该任务用于替代应用程序Info.plist中的值

class AppDelegate: UIResponder, UIApplicationDelegate {
.....
   func application(application: UIApplication, supportedInterfaceOrientationsForWindow window: UIWindow?) -> UIInterfaceOrientationMask {
        return UIInterfaceOrientationMask.AllButUpsideDown;//UIInterfaceOrientationMask.All for iPad devices

    }
}

你是怎么找到的？@Flakerim:不，我还没有找到答案。。。你有同样的问题吗？是的，可以。您可以通过编程方式执行此操作，请查看以下帖子：
