MPMoviePlayerViewController和MPMoviePlayerController 使用場合不一樣
MPMoviePlayerViewController是在iOS3.2以后的平台上使用。MPMoviePlayerController在3.2之前使用,雖然在3.2之后也能使用,但是使用方法略有改變,建議3.2之后使用MPMoviePlayerViewController。
3.2之后,MPMoviePlayerController作為MPMoviePlayerViewController的一個屬性存在。
以下是使用MPMoviePlayerViewController播放視頻的代碼:
- (void) playVideo:(NSURL *) movieURL//根據視頻url播放視頻 { playerViewController = [[MPMoviePlayerViewController alloc] initWithContentURL:movieURL]; [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(playVideoFinished:) name:MPMoviePlayerPlaybackDidFinishNotification object:[playerViewController moviePlayer]]; playerViewController.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal; [self presentModalViewController:playerViewController animated:YES]; MPMoviePlayerController *player = [playerViewController moviePlayer]; [player play]; } - (void) playVideoFinished:(NSNotification *)theNotification//當點擊Done按鍵或者播放完畢時調用此函數 { MPMoviePlayerController *player = [theNotification object]; [[NSNotificationCenter defaultCenter] removeObserver:self name:MPMoviePlayerPlaybackDidFinishNotification object:player]; [player stop]; [playerViewController dismissModalViewControllerAnimated:YES]; }
