在ios5中使用MPMoviePlayer控制器播放視頻

Question

我從本地項目resource.i上播放mpmovieplayercontroller上的視頻，我正在啓動顯示一些錯誤的應用程序控制臺，以及如何在mpmovieplayercontroller或mpmovieplayercontroller中修復和播放適當的方式。下面顯示了我在控制檯輸出，但應用程序得到的錯誤不會崩潰：

這裏是我的代碼用於播放視頻：

#import "VideoPlayerControllerViewController.h" 

@interface VideoPlayerControllerViewController() 

@end 

@implementation VideoPlayerControllerViewController 
@synthesize moviePlayer; 

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

} 

- (void)viewDidUnload 
{ 
    [super viewDidUnload]; 
    // Release any retained subviews of the main view. 
} 

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation 
{ 
    return (interfaceOrientation != UIInterfaceOrientationPortraitUpsideDown); 
} 
-(void)moviePlayBackDidFinish:(NSNotification*)aNotification{ 
    NSLog(@"Play Back Finished!"); 
    [moviePlayer play]; 
} 
-(void)playMovie 
{ 
    NSURL *url = [NSURL fileURLWithPath:[[NSBundle mainBundle] 
             pathForResource:@"Menu_Free" ofType:@"mp4"]]; 
    moviePlayer = [[MPMoviePlayerController alloc] 
        initWithContentURL:url]; 

    [[NSNotificationCenter defaultCenter] addObserver:self 
              selector:@selector(moviePlayBackDidFinish:) 
               name:MPMoviePlayerPlaybackDidFinishNotification 
               object:moviePlayer]; 

    moviePlayer.controlStyle = MPMovieControlStyleDefault; 
    moviePlayer.shouldAutoplay = YES; 
    moviePlayer.view.frame = self.view.bounds; 
    moviePlayer.scalingMode= MPMovieScalingModeFill; 
    moviePlayer.controlStyle =MPMovieControlStyleNone; 
    [self.view addSubview:moviePlayer.view]; 
    [moviePlayer setFullscreen:YES animated:YES]; 
} 

@end 

先謝謝了！

替換你的方法與此...

-(void)playMovie 
{ 
    NSURL *url = [NSURL fileURLWithPath:[[NSBundle mainBundle] 
             pathForResource:@"Menu_Free.mp4" ofType:@""]]; 
    moviePlayer = [[MPMoviePlayerController alloc] 
        initWithContentURL:url]; 

    [[NSNotificationCenter defaultCenter] addObserver:self 
              selector:@selector(moviePlayBackDidFinish:) 
               name:MPMoviePlayerPlaybackDidFinishNotification 
               object:moviePlayer]; 

    moviePlayer.controlStyle = MPMovieControlStyleDefault; 
    moviePlayer.shouldAutoplay = YES; 
    moviePlayer.view.frame = self.view.bounds; 
    moviePlayer.scalingMode= MPMovieScalingModeFill; 
    moviePlayer.controlStyle =MPMovieControlStyleNone; 
    [self.view addSubview:moviePlayer.view]; 
    [moviePlayer setFullscreen:YES animated:YES]; 
}
