Iphone 如何更改MPMoviePlayServiceWController的UIModalTransitionStyle

当我使用mpmovieplayervicewcontroller时，除了默认的向上滑动动画之外，我似乎无法将modalTransitionStyle更改为任何其他内容

还有其他人能让这个工作吗

MPMoviePlayerViewController* theMoviePlayer = [[MPMoviePlayerViewController alloc] initWithContentURL:[NSURL fileURLWithPath:videoURL]];
theMoviePlayer.modalTransitionStyle = UIModalTransitionStyleCrossDissolve; // doesn't work
[self presentMoviePlayerViewControllerAnimated:theMoviePlayer];

感谢您观看

这里的代码似乎还将呈现

mpmovieplayervicewcontroller

实例的视图控制器的

modalTransitionStyle

设置为相同的值。这行得通吗？

我发现用CrossDisolve模式动画启动“MPMoviePlayServiceController”实例的方法是在导航控制器内启动电影播放器，如下所示：

NSURL * videoUrl = [[NSURL alloc] initFileURLWithPath:videoPath];
MPMoviePlayerViewController * moviePlayerController = [[MPMoviePlayerViewController alloc] initWithContentURL:videoUrl];

UINavigationController * navController = [[UINavigationController alloc] initWithRootViewController:moviePlayerController];
navController.modalTransitionStyle = UIModalTransitionStyleCrossDissolve;
[navController setNavigationBarHidden:YES];

[self presentViewController:navController animated:YES completion:nil];

以及收听MPMoviePlayerPlaybackDidFinishNotification通知：

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(movieDidFinish:) name:MPMoviePlayerPlaybackDidFinishNotification object:nil];

并在视频结束后将其关闭：

-(void)movieDidFinish:(NSNotification *)notification {

    [self dismissViewControllerAnimated:YES completion:nil];
}

埃卡里翁的回答非常有帮助——这是一个快速的版本，希望能为人们节省一些时间

import MediaPlayer

class ViewController: UIViewController {

    ...

    func playAction() {

    // setup the media player view
    var url:NSURL = NSURL(string: "http://jplayer.org/video/m4v/Big_Buck_Bunny_Trailer.m4v")!
    var moviePlayerView = MPMoviePlayerViewController(contentURL: url)
    moviePlayerView.moviePlayer.controlStyle = MPMovieControlStyle.None
    moviePlayerView.moviePlayer.repeatMode = MPMovieRepeatMode.None

    // register the completion
    NSNotificationCenter.defaultCenter().addObserver(self,
        selector: "videoHasFinishedPlaying:",
        name: MPMoviePlayerPlaybackDidFinishNotification,
        object: nil)

    // instantiate nav controller and add the moviePlayerView as its root
    var navController = UINavigationController(rootViewController:  moviePlayerView)

    // set transition (this is what overrides the animated "slide up" look
    navController?.modalTransitionStyle = UIModalTransitionStyle.CrossDissolve
    navController?.setNavigationBarHidden(true, animated: false)

    // present the nav controller
    self.presentViewController(navController!, animated: true, completion: nil)
}


func videoHasFinishedPlaying(notification: NSNotification){
    println("Video finished playing")

    self.dismissViewControllerAnimated(false, completion: nil)
    NSNotificationCenter.defaultCenter().removeObserver(self)

    let reason =
    notification.userInfo![MPMoviePlayerPlaybackDidFinishReasonUserInfoKey]
        as NSNumber?

    if let theReason = reason{

        let reasonValue = MPMovieFinishReason(rawValue: theReason.integerValue)

        switch reasonValue!{
        case .PlaybackEnded:
            // The movie ended normally
            println("Playback Ended")
        case .PlaybackError:
            // An error happened and the movie ended
            println("Error happened")
        case .UserExited:
            // The user exited the player
            println("User exited")
        default:
            println("Another event happened")
        }
    }
}

谢谢，沙吉。事实上，它并没有完全起作用——但秘密就在你指给我的密码里。如果您使用新的[self-PresentMoviePlayeServiceController激活：移动层]；然后，将忽略过渡样式。但是，如果使用标准的[self-presentModalViewController:animated:]，则它适用于电影的过渡，但在电影结束时仍使用默认幻灯片动画。古怪的哦，这个链接有一些非常好的技巧，可以让3.1/2和4.0兼容的电影播放。干杯
