iOS mpmovieplayercontroller

** 개인적 메모입니다. 태클 사절 **

Apple made significant changes to the MPMoviePlayerController API:s in iOS 3.2. Before, all you had to do was to initialize the MPMoviePlayerController and call play. Now things are a bit more complicated because videos can be played on a portion of the screen (good for the iPad) and not just in full screen mode.

But if all you want is to play a video in full-screen mode on all versions of the OS, then here’s some code:

1. NSURL *url = [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:introVideoFileName ofType:@""]];  
2. MPMoviePlayerController *moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:url];  
3.   
4. // Register to receive a notification when the movie has finished playing.  
5. [[NSNotificationCenter defaultCenter] addObserver:self  
6.                                          selector:@selector(moviePlayBackDidFinish:)  
7.                                              name:MPMoviePlayerPlaybackDidFinishNotification  
8.                                            object:moviePlayer];  
9.   
10. if ([moviePlayer respondsToSelector:@selector(setFullscreen:animated:)]) {  
11.   // Use the new 3.2 style API  
12.   moviePlayer.controlStyle = MPMovieControlStyleNone;  
13.   moviePlayer.shouldAutoplay = YES;  
14.   [self.view addSubview:moviePlayer.view];  
15.   [moviePlayer setFullscreen:YES animated:YES];  
16. } else {  
17.   // Use the old 2.0 style API  
18.   moviePlayer.movieControlMode = MPMovieControlModeHidden;  
19.   [moviePlayer play];  
20. }

2.   MPMoviePlayerController *moviePlayer = [notification object];  
3.   [[NSNotificationCenter defaultCenter] removeObserver:self  
4.                                                   name:MPMoviePlayerPlaybackDidFinishNotification  
5.                                                 object:moviePlayer];  
6.   
7.   // If the moviePlayer.view was added to the view, it needs to be removed  
8.   if ([moviePlayer respondsToSelector:@selector(setFullscreen:animated:)]) {  
9.     [moviePlayer.view removeFromSuperview];  
10.   }  
11.   
12.   [moviePlayer release];  
13. }  

 

Recently I’ve been doing some development using cocos2d and I had to make some small changes to the code. (If your app is in portrait mode, then you may not have to do the rotation transform shown below.)

16.   [moviePlayer.view setTransform:CGAffineTransformMakeRotation((float)M_PI_2)];  
17.   CGSize winSize = [[CCDirector sharedDirector] winSize];  
18.   moviePlayer.view.frame = CGRectMake(0, 0, winSize.height, winSize.width);// width and height are swapped after rotation  
19.   [[[CCDirector sharedDirector] openGLView] addSubview:moviePlayer.view];

21.   // Use the old 2.0 style API  
22.   moviePlayer.movieControlMode = MPMovieControlModeHidden;  
23.   [moviePlayer play];
