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模拟器中，视频无法播放。请提供任何建议。

Answer 1

您忘了展示或添加为子视图

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

Answer 2

试用此代码

 - (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];
    }
