On iOS, if you encounter the need to play a movie, such as the animation ..., we are accustomed to use MediaPlayer to play the movie, because it is very convenient to use, so it has been used. But the more demanding the customer is, the more serious it is, especially when it comes to the animation or interaction effect. So if you gimps with a film in some of the animations, the machine will not run. So after iOS 4, we can use Avplayer to do a more subtle operation.
Note:
- MediaPlayer's film is placed in the UIView, and Avplayer is placed in Avplayerlayer, Avplayerlayer is the sub-category of Calayer.
- Before using MediaPlayer, remember to join Mediaplayer.framework and #import <MediaPlayer/MediaPlayer.h>
- Before using Avplayer, remember to join AVFOUNDATION.FRAMEWORKK and #import <AVFoundation/AVFoundation.h>
Please refer to the following example:
Use MediaPlayer to play a movie
[CPP]View Plaincopy
- nsstring *filepath = [[NSBundle mainbundle] pathforresource:@"backspace" oftype:@ "mov" ];
- Nsurl *sourcemovieurl = [Nsurl Fileurlwithpath:filepath];
- MoviePlayer = [[MPMoviePlayerController alloc] initwithcontenturl:sourcemovieurl];
- Movieplayer.view.frame=cgrectmake (0, 0, 1024, 768);
- Movieplayer.controlstyle=mpmoviecontrolstylenone;
- //Play the movie!
- [Self.view AddSubview:moviePlayer.view];
Use Avplayer to play a movie
[CPP]View Plaincopy
- nsstring *filepath = [[NSBundle mainbundle] pathforresource:@"backspace" oftype:@ "mov" ];
- Nsurl *sourcemovieurl = [Nsurl Fileurlwithpath:filepath];
- Avasset *movieasset = [Avurlasset urlassetwithurl:sourcemovieurl options:nil];
- Avplayeritem *playeritem = [Avplayeritem playeritemwithasset:movieasset];
- Avplayer *player = [Avplayer Playerwithplayeritem:playeritem];
- Avplayerlayer *playerlayer = [Avplayerlayer Playerlayerwithplayer:player];
- Playerlayer.frame = Self.view.layer.bounds;
- playerlayer.videogravity = Avlayervideogravityresizeaspect;
- [Self.view.layer Addsublayer:playerlayer];
- [Player play];
