【问题描述】：

我正在尝试我在iOS6 期间从事的一个项目。尝试在iOS8 上运行相同的视频，视频正在播放。我还有什么需要做的吗？

- (void) viewDidAppear:(BOOL)animated {
    [super viewDidAppear:animated];


    NSString *filepath   =   [[NSBundle mainBundle] pathForResource:@"Mcdonald" ofType:@"mp4"];

    NSURL    *fileURL    =   [NSURL fileURLWithPath:filepath];
    MPMoviePlayerController *moviePlayerController = [[MPMoviePlayerController alloc] initWithContentURL:fileURL];

    [moviePlayerController.view setFrame:[UIScreen mainScreen].bounds];

    [self.view addSubview:moviePlayerController.view];
    moviePlayerController.fullscreen = YES;
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(playMovie:) name:MPMoviePlayerLoadStateDidChangeNotification object:moviePlayerController];
}

- (void)playMovie:(NSNotification *)notification {
    MPMoviePlayerController *player = notification.object;
    if (player.loadState & MPMovieLoadStatePlayable)
    {
        NSLog(@"Movie is Ready to Play");
        [player play];
    }
}

谢谢。

最后。将它添加到UIWindow 为我解决了这个问题。

NSBundle *bundle = [NSBundle mainBundle];
NSString *moviePath = [bundle pathForResource:@"disc" ofType:@"mp4"];
NSURL *movieURL = [[NSURL fileURLWithPath:moviePath] retain];

theMoviPlayer = [[MPMoviePlayerController alloc] initWithContentURL:movieURL];
theMoviPlayer.controlStyle = MPMovieControlStyleFullscreen;
theMoviPlayer.view.transform = CGAffineTransformConcat(theMoviPlayer.view.transform, CGAffineTransformMakeRotation(M_PI_2));
UIWindow *backgroundWindow = [[UIApplication sharedApplication] keyWindow];
[theMoviPlayer.view setFrame:backgroundWindow.frame];
[backgroundWindow addSubview:theMoviPlayer.view];
[theMoviPlayer play];

【解决方案2】：

在 .h 文件中初始化您的 MPMoviePlayerController，如下所示：

@property(strong,nonatomic)MPMoviePlayerController *moviePlayerController;

经过上述更改后，它将起作用。

示例代码：

@interface ViewController : UIViewController

@property(strong,nonatomic)MPMoviePlayerController *moviePlayerController;

@end




@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.

     NSString *filepath   =   [[NSBundle mainBundle] pathForResource:@"Mcdonald" ofType:@"mp4"];

     NSURL    *fileURL    =   [NSURL fileURLWithPath:filepath];
    _moviePlayerController = [[MPMoviePlayerController alloc] initWithContentURL:fileURL];

    _moviePlayerController.allowsAirPlay = NO;
    _moviePlayerController.shouldAutoplay = YES;
    [_moviePlayerController.view setFrame:[UIScreen mainScreen].bounds];
    _moviePlayerController.controlStyle=MPMovieControlStyleEmbedded;


    [self.view addSubview:_moviePlayerController.view];
    _moviePlayerController.fullscreen = YES;
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(playMovie:) name:MPMoviePlayerLoadStateDidChangeNotification object:moviePlayerController];

}

- (void) viewDidAppear:(BOOL)animated {
    [super viewDidAppear:animated];

   }
- (void)playMovie:(NSNotification *)notification {
    MPMoviePlayerController *player = notification.object;
    if (player.loadState & MPMovieLoadStatePlayable)
    {
        NSLog(@"Movie is Ready to Play");
        [player play];
    }
}

- (void)didReceiveMemoryWarning {
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}



@end
