斯威夫特：播放视频在风景模式下全屏

我有这样的代码：斯威夫特：播放视频在风景模式下全屏

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. 
    } 

}

它的工作原理，从服务器播放视频，但我这里有一个问题：

，如果我想有肖像模式应用程序，只有当用户以全屏模式播放视频时，我仍然可以将其变为横向格式吗？如果是的话，该怎么做？

以前感谢。

你找到它怎么样？ – flakerimi 2015-01-03 22:49:39

@Flakerim：不，我还没有找到答案...你有同样的问题吗？ – 2015-01-22 08:32:04

是的，可以做到。你可以通过编程来实现，查看这篇文章：http://stackoverflow.com/questions/25651969/setting-device-orientation-in-swift-ios – JaySH 2015-05-20 15:54:35

是的。当MPMoviePlayercontroller进入全屏模式时，您可以强制更改方向。只需添加通知MPMoviePlayerWillEnterFullscreenNotification观测到您的viewDidLoad/viewWillAppear中，并改变方向如下

 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") 
    }

不要忘记删除观察者。

应用程序委托可以实现application：supportedInterfaceOrientationsForWindow：返回一个UIInterfaceOrientationMask，用于代替应用程序的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 

    } 
}
