MPMoviePlayerViewController实现横屏播放

实现播放视频的时候自动横屏必须重写MPMoviePlayerViewController，具体代码如下：

1.重写MPMoviePlayerViewController

////  DirectionMPMoviePlayerViewController.h//  Direction////  Created by apple on 12-4-10.//  Copyright (c) 2012年 __MyCompanyName__. All rights reserved.//#import <MediaPlayer/MediaPlayer.h>@interface DirectionMPMoviePlayerViewController : MPMoviePlayerViewController@end

?

////  DirectionMPMoviePlayerViewController.m//  Direction////  Created by apple on 12-4-10.//  Copyright (c) 2012年 __MyCompanyName__. All rights reserved.//#import "DirectionMPMoviePlayerViewController.h"@implementation DirectionMPMoviePlayerViewController- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation{    return UIDeviceOrientationIsLandscape(interfaceOrientation);}@end

?

2.初始化播放器，播放

- (void)viewDidLoad{    [super viewDidLoad];    // Do any additional setup after loading the view from its nib.    [self customTitleView];    NSString *mystr = @"http://114.112.50.220:8080/res/20120331/2FFCE63A-C997-4D8C-4C4F-4127D78A958E.m3u8";    NSURL *myURL = [[NSURL alloc] initWithString:mystr];    [self playMovieAtURL:myURL];}-(void)playMovieAtURL:(NSURL*)theURL{    playerView = [[DirectionMPMoviePlayerViewController alloc] initWithContentURL:theURL];    playerView.view.frame = self.view.frame;//全屏播放（全屏播放不可缺）    playerView.moviePlayer.scalingMode = MPMovieScalingModeAspectFill;//全屏播放（全屏播放不可缺）    [[NSNotificationCenter defaultCenter] addObserver:self                                             selector:@selector(myMovieFinishedCallback:)                                                 name:MPMoviePlayerPlaybackDidFinishNotification                                               object:playerView];    [playerView.moviePlayer play];    [self presentMoviePlayerViewControllerAnimated:playerView];}// When the movie is done, release the controller.-(void)myMovieFinishedCallback:(NSNotification*)aNotification{    DirectionMPMoviePlayerViewController* theMovie = [aNotification object];    [[NSNotificationCenter defaultCenter] removeObserver:self                                                    name:MPMoviePlayerPlaybackDidFinishNotification                                                  object:theMovie];        [theMovie release];}
