Question

我正在下载一个aac文件并在MPMoviePlayerController中使用以下代码

播放它

movieController = [[MPMoviePlayerController alloc] initWithContentURL:[NSURL fileURLWithPath:self.filePath]];
[self.view addSubview:movieController.view];
CGRect screenBound = [[UIScreen mainScreen] bounds];
CGSize screenSize = screenBound.size;
movieController.view.frame = CGRectMake(0,0,screenSize.width, screenSize.height);
[movieController setFullscreen:YES];
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(doneBtnMediaPlayer:) name:MPMoviePlayerWillExitFullscreenNotification object:nil];

movieController是（非原子的，强大的）类属性

这适用于除iOS 5（和iOS 5模拟器）之外的所有iOS。在iOS 5中，它显示黑屏，文件在后台播放。

我注意到的另一件事是，当我在已经存在的应用程序上运行应用程序时，它在iOS5上的工作正常。但是，当我从设备中删除应用程序然后运行它时，它只显示黑屏。

看看这是否有帮助：

这是您的标题（.h）文件＃进口 #import

@interface ViewController : UIViewController

@property(nonatomic,retain)MPMoviePlayerViewController *playerController;

@end

这是你的实现文件（.m） #import“ViewController.h”

@interface ViewController ()

@end

@implementation ViewController
@synthesize playerController;

- (void)viewDidLoad
{
    [super viewDidLoad];
NSURL *url = [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:@"gold etche" ofType:@"mov"]];
playerController = [[MPMoviePlayerViewController alloc]initWithContentURL:url];
[self presentMoviePlayerViewControllerAnimated:playerController];
[self.view insertSubview:playerController.view atIndex:0];
playerController.moviePlayer.movieSourceType = MPMovieSourceTypeFile;
playerController.moviePlayer.controlStyle = MPMovieControlStyleDefault;
playerController.moviePlayer.scalingMode = MPMovieScalingModeNone;

[playerController.moviePlayer play];

}

- (void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];

}

@end

我在IOS 5（5.0和5.1）和IOS 6中测试了这一点，并且一切都很精致

MPMoviePlayerController仅在iOS 5中显示黑屏
