ios - 安装 Xcode 4.5，MPMoviePlayerController 不再工作

Question

我很高兴地看到，当“升级”到 Xcode 4.5 时，我的应用程序中的视频现在根本无法播放。

通常我会这样做:

self.moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:[self getBundleClip:@"theVideo"]];
self.moviePlayer.controlStyle = MPMovieControlStyleNone;
self.moviePlayer.shouldAutoplay = YES;
self.moviePlayer.repeatMode = MPMovieRepeatModeOne;
self.moviePlayer.view.frame = self.container.frame;
self.moviePlayer.view.userInteractionEnabled = NO;
[self.container addSubview:self.moviePlayer.view];

- (NSURL*)getBundleClip:(NSString*)clip
{
    NSBundle *bundle = [NSBundle mainBundle];
    NSString *moviePath = [bundle pathForResource:clip ofType:@"mp4"];
    return [NSURL fileURLWithPath:moviePath];
}

同样，在我将 Xcode 更新到 4.5 之前，一切都运行良好。还有其他人有这个问题吗？

我也得到了这个输出:

[MPAVController] Autoplay: Disabling autoplay for pause
[MPAVController] Autoplay: Disabling autoplay

我想你是在函数中定义它吧？

如果使用ARC，则必须保留MPMoviePlayerController

将其添加到接口(interface)文件中!

@property(nonatomic, strong) MPMoviePlayerController *moviePlayer;
