Question

所以我正在使用ASIHTTPRequest从我的FTP下载视频文件。它下载并将其作为文件的目录路径：

/Users/Matt_Sich/Library/Application Support/iPhone Simulator/5.0/Applications/B7366FF2-7592-4ED0-ABC2-46BA111D0FF4/Documents/INWD.mp4

好了，现在我想要播放那个视频......我想这样做很容易，但由于某种原因，我无法让它发挥作用。我得到的只是一个黑色的视图，就是这样。

//NSURL *url = [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:@"Park_iPod" ofType:@"mp4"]];
NSURL *url = [NSURL URLWithString:self.PathString];
moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:url];

[self.view addSubview:moviePlayer.view];
[moviePlayer setFullscreen:YES animated:YES];

（注意：self.PathString是我上面提到的下载文件的路径）它播放来自主捆绑的视频就好了，所以我确定文件路径有问题。

Answer 1

下载文件后，您需要使用fileURLWithPath来访问该文件，而不是URLWithString

NSURL *url = [NSURL fileURLWithPath.PathString];

Answer 2

这会让你获得文件目录......

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];

Answer 3

    moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:([NSURL fileURLWithPath : self.PathString])];

    [moviePlayer setShouldAutoplay:NO];
    [moviePlayer setFullscreen:YES animated:YES];
    [moviePlayer setScalingMode:MPMovieScalingModeAspectFit];

    // Register for the playback finished notification
    [[NSNotificationCenter defaultCenter] 
        addObserver: self
        selector: @selector(movieFinishedCallback:)
        name: MPMoviePlayerPlaybackDidFinishNotification
        object: moviePlayer];

    // Register that the load state changed (movie is ready)
    [[NSNotificationCenter defaultCenter] 
        addObserver:self 
        selector:@selector(moviePlayerLoadStateChanged:) 
        name:MPMoviePlayerLoadStateDidChangeNotification 
        object: moviePlayer];

    [self.view addSubview: moviePlayer.view];
    [moviePlayer.view setFrame: self.view.bounds];

    [moviePlayer prepareToPlay];
