嗨,我已经创建了iPad的应用程序,它有一个资源文件夹中的视频文件,它播放时,用户单击播放按钮。 它适用于第一次用户点击播放按钮,但当用户播放视频文件的后续时间。问题发生的是视频不播放只有音频正在播放。这些问题不会随机发生,但会发生更多次。mpmovieplayercontroller问题ipad
在发生问题时还有一件事(视频不播放),当我点击位于播放器右下角的wo-arrow图标时,电影将全屏显示,并显示视频。在实时视频正在播放。
任何人都可以帮助我吗?
这是我的示例代码
MPMoviePlayerController *moviePlayer;
} @property(读写,保留)的MPMoviePlayerController * moviePlayer; @synthesize moviePlayer;
- (void)viewDidLoad {
[[NSNotificationCenter defaultCenter]
addObserver:self
selector:@selector(movieFinishedCallback:)
name:MPMoviePlayerPlaybackDidFinishNotification
object:self.moviePlayer];
[super viewDidLoad];
}
-(IBAction)PlayBtnPressed:(id)sender
{
NSURL *movieURL;
NSString *moviePath = [[NSBundle mainBundle] pathForResource:@"title" ofType:@"mp4"];
movieURL = [NSURL fileURLWithPath:moviePath];
// Initialize a movie player object with the specified URL
MPMoviePlayerController *mp = [[MPMoviePlayerController alloc] initWithContentURL:movieURL];
if (mp)
{
// save the movie player object
self.moviePlayer = mp;
[mp release];
UIInterfaceOrientation orientation = [[UIDevice currentDevice]orientation];
[self shouldAutorotateToInterfaceOrientation:orientation];
// Play the movie!
[self.view addSubview:self.moviePlayer.view];
[self.moviePlayer play];
}
}
- (void) movieFinishedCallback:(NSNotification*) aNotification {
NSLog(@"movieFinishedCallback aNotification");
MPMoviePlayerController *player = [aNotification object];
[[NSNotificationCenter defaultCenter]
removeObserver:self
name:MPMoviePlayerPlaybackDidFinishNotification
object:player];
[player stop];
[player.view removeFromSuperview];
}
在此先感谢........
