Question

我正在尝试在视图加载时全屏播放一个简单的mp4文件。这是代码：

我根本没有收到视频，但我知道正在调用viewDidLoad并且存在一个视图。

@interface WatchLiveViewController ()

@end

@implementation WatchLiveViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
    NSURL *movieURL = [NSURL URLWithString:@"http://download.wavetlan.com/SVV/Media/HTTP/H264/Talkinghead_Media/H264_test1_Talkinghead_mp4_480x360.mp4"];
    MPMoviePlayerController *moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:movieURL];
    moviePlayer.controlStyle = MPMovieControlStyleFullscreen;
    moviePlayer.view.transform = CGAffineTransformConcat(moviePlayer.view.transform, CGAffineTransformMakeRotation(M_PI_2));
    UIWindow *backgroundWindow = [[UIApplication sharedApplication] keyWindow];
    [moviePlayer.view setFrame:backgroundWindow.frame];
    [backgroundWindow addSubview:moviePlayer.view];
    [moviePlayer play];
}

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

@end

Answer 1

试试这段代码：

MPMoviePlayerViewController *mpvController = [[MPMoviePlayerViewController alloc] initWithContentURL:movieURL];
mpvController.moviePlayer.controlStyle = MPMovieControlStyleFullscreen;
mpvController.moviePlayer.scalingMode = MPMovieScalingModeFill;
mpvController.view.transform = CGAffineTransformConcat(mpvController.view.transform, CGAffineTransformMakeRotation(M_PI_2));
[self presentViewController:mpvController animated:NO completion:^{
    [mpvController.moviePlayer play];
}];

Answer 2

我认为你遗失了prepareToPlay。尝试这样的事情：

...
[moviePlayer prepareToPlay];
[moviePlayer play];

iOS无法播放视频
