從url播放視頻

Question

- (void)viewDidLoad 
{ 
    [super viewDidLoad]; 

    MPMoviePlayerController *player; 
    NSLog(@"%@",gotVideo); 
    NSURL *urlString=[NSURL URLWithString:gotVideo]; 
    player = [[MPMoviePlayerController alloc] initWithContentURL:urlString]; 


    [[NSNotificationCenter defaultCenter] 
    addObserver:self 
    selector:@selector(movieFinishedCallback:) 
    name:MPMoviePlayerPlaybackDidFinishNotification 
    object:player]; 


    //---play movie--- 
    [player play]; 

} 

- (void) movieFinishedCallback:(NSNotification*) aNotification { 
    MPMoviePlayerController *player = [aNotification object]; 
    [[NSNotificationCenter defaultCenter] 
    removeObserver:self 
    name:MPMoviePlayerPlaybackDidFinishNotification 
    object:player]; 
} 

在iOS 7.1模擬器中，視頻未播放。請提供任何建議。

Answer 1

你忘了出示，或添加爲子視圖

[self presentMoviePlayerViewControllerAnimated:player]; 
//---play movie--- 
[player play]; 

Answer 2

試試這個代碼

- (void)viewDidLoad 
    { 
     [super viewDidLoad]; 


NSURL *urlString=[NSURL URLWithString: urlString]; 
     MPMoviePlayerController *player = [[MPMoviePlayerController alloc] initWithContentURL: urlString]; 
       [player.view setFrame:CGRectMake(//set rect frame)]; 
       player.controlStyle = MPMovieControlStyleDefault; 
       player.shouldAutoplay=YES; 
       player.repeatMode = NO; 
       [player setFullscreen:YES animated:NO]; 
       [player prepareToPlay]; 
       [player play]; 
    [self.view addsubview: player.view]; 

     [[NSNotificationCenter defaultCenter] 
     addObserver:self 
     selector:@selector(movieFinishedCallback:) 
     name:MPMoviePlayerPlaybackDidFinishNotification 
     object:player]; 

    } 
    - (void) movieFinishedCallback:(NSNotification*) aNotification { 
     MPMoviePlayerController *player = [aNotification object]; 
     [[NSNotificationCenter defaultCenter] 
     removeObserver:self 
     name:MPMoviePlayerPlaybackDidFinishNotification 
     object:player]; 
    }
