MPMoviePlayerViewController 和 MPMoviePlayerController

ios播放视频文件一般使用 MPMoviePlayerViewController 和 MPMoviePlayerController。这两者的区别就是MPMoviePlayerViewController里面包含了一个MPMoviePlayerController先说MPMoviePlayerController首先要包含 #import <MediaPlayer/MediaPlayer.h>头文件和MediaPlayer.framework。- (void)createMPPlayerController:(NSString *)sFileNamePath {  NSURL *movieURL = [NSURL fileURLWithPath:sFileNamePath]; MPMoviePlayerController *movewController =[[MPMoviePlayerController alloc] initWithContentURL:movieURL]; [movewController prepareToPlay]; [self.view addSubview:movewController.view];//设置写在添加之后   // 这里是addSubView movewController.shouldAutoplay=YES; [movewController setControlStyle:MPMovieControlStyleDefault]; [movewController setFullscreen:YES]; [movewController.view setFrame:self.view.bounds]; 这里注册相关操作的通知 [[NSNotificationCenter defaultCenter] addObserver:self                                             selector:@selector(movieFinishedCallback:)                                                 name:MPMoviePlayerPlaybackDidFinishNotification                                               object:moveViewController.movewController]; //播放完后的通知 [movewController release];}-(void)movieFinishedCallback:(NSNotification*)notify {    MPMoviePlayerController* theMovie = [notifyobject];    [[NSNotificationCenterdefaultCenter] removeObserver:self                                                    name:MPMoviePlayerPlaybackDidFinishNotification                                                  object:theMovie];    [theMovie.view removeFromSuperview];    [theMovie release];}//////////////////////////////// end2.介绍下MPMoviePlayerViewController。 注意：MPMoviePlayerViewController 必须 presentMoviePlayerViewControllerAnimated方式添加，否则Done按钮是不会响应通知MPMoviePlayerPlaybackDidFinishNotification事件的；- (void)createMPPlayerController:(NSString *)sFileNamePath {    MPMoviePlayerViewController *moviePlayer =[[MPMoviePlayerViewControlleralloc] initWithContentURL:[NSURLfileURLWithPath:sFileNamePath]];    [moviePlayer.moviePlayerprepareToPlay];    [selfpresentMoviePlayerViewControllerAnimated:moviePlayer]; // 这里是presentMoviePlayerViewControllerAnimated    [moviePlayer.moviePlayersetControlStyle:MPMovieControlStyleFullscreen];    [moviePlayer.view setBackgroundColor:[UIColor clearColor]];    [moviePlayer.view setFrame:self.view.bounds];    [[NSNotificationCenterdefaultCenter] addObserver:self                                             selector:@selector(movieFinishedCallback:)                                                 name:MPMoviePlayerPlaybackDidFinishNotification                                               object:moviePlayer.moviePlayer];    [moviePlayer release];}-(void)movieStateChangeCallback:(NSNotification*)notify  {   //点击播放器中的播放/ 暂停按钮响应的通知}-(void)movieFinishedCallback:(NSNotification*)notify{   // 视频播放完或者在presentMoviePlayerViewControllerAnimated下的Done按钮被点击响应的通知。    MPMoviePlayerController* theMovie = [notifyobject];    [[NSNotificationCenterdefaultCenter] removeObserver:self                                                    name:MPMoviePlayerPlaybackDidFinishNotification                                                  object:theMovie];    [selfdismissMoviePlayerViewControllerAnimated];}
