嗨,我已經創建了iPad的應用程序,它有一個資源文件夾中的視頻文件,它播放時,用戶單擊播放按鈕。 它適用於第一次用戶點擊播放按鈕,但當用戶播放視頻文件的後續時間。問題發生的是視頻不播放只有音頻正在播放。這些問題不會隨機發生,但會發生更多次。mpmovieplayercontroller問題ipad
在發生問題時還有一件事(視頻不播放),當我點擊位於播放器右下角的wo-arrow圖標時,電影將全屏顯示,並顯示視頻。在實時視頻正在播放。
任何人都可以幫助我嗎?
這是我的示例代碼
MPMoviePlayerController *moviePlayer;
} @property(讀寫,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];
}
在此先感謝........
