ios 播放視頻

建立Empty Application，添加HomeViewController

 HomeViewController.h代碼

 #import <UIKit/UIKit.h>#import <MediaPlayer/MediaPlayer.h> @interface HomeViewController : UIViewController{     MPMoviePlayerViewController *playerViewController;} - (IBAction)buttonClicked:(id)sender;  

@end 

HomeViewController.m代碼

 

 #import "HomeViewController.h" @interface HomeViewController () @end @implementation HomeViewController  //當影片播放完畢或者使用者在影片播放時單擊Done按鈕時，調用moviePlayerDidFinish方法，並傳遞了一個MPMoviePlayerController類型的對象，它是MPMoviePlayerViewController類的一個屬性，MPMoviePlayerController是自動被建立的，用於接受命令但我們不能修改它，可以使用它來管理和配置影片的播放。 //在moviePlayerDidFinish方法中擷取到MPMoviePlayerController對象，然後移去NSNotificationCenter的訊息通知，停止影片的播放，移去影片播放視圖，並釋放MPMoviePlayerViewController對象。- (void)moviePlayerDidFinish:(NSNotification *)aNote{     MPMoviePlayerController *player = [aNote object];    [[NSNotificationCenter defaultCenter] removeObserver:self                                                    name:MPMoviePlayerPlaybackDidFinishNotification                                                  object:player];    [player stop];    [self dismissMoviePlayerViewControllerAnimated];        [playerViewController release];}  - (IBAction)buttonClicked:(id)sender {    /*本地視頻播放    NSString *filePath =[[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:@"movie.mov"];    NSURL *movieURL = [NSURL fileURLWithPath:filePath];     */        //通過http播放視頻檔案    NSURL *movieURL = [NSURL URLWithString:@"http://www.5i-dream.cn/mkovie.mov"];        playerViewController = [[MPMoviePlayerViewController alloc] initWithContentURL:movieURL];        [[NSNotificationCenter defaultCenter] addObserver:self                                              selector:@selector(moviePlayerDidFinish:)                                                  name:MPMoviePlayerPlaybackDidFinishNotification                                                object:[playerViewController moviePlayer]];        [self presentMoviePlayerViewControllerAnimated:playerViewController];//呈現這個影片播放視圖} @end
