Ios MPMoviePlayerViewController在所有方向

我正在开发一个应用程序，我的应用程序只支持纵向

支持的方向：

现在我在viewController中使用MPMoviePlayerViewController。现在需要以横向和纵向模式显示视频。我怎样才能做到这一点。我用于MPMovieViewController的代码是：

    -(void) playVideo
{
    movieplayer = [[MPMoviePlayerViewController alloc] initWithContentURL:[NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:@"abc" ofType:@"mp4"]]];

    [[NSNotificationCenter defaultCenter] removeObserver:movieplayer
                                                    name:MPMoviePlayerPlaybackDidFinishNotification
                                                  object:movieplayer.moviePlayer];

    // Register this class as an observer instead
    [[NSNotificationCenter defaultCenter] addObserver:self
                                             selector:@selector(movieFinishedCallback:)
                                                 name:MPMoviePlayerPlaybackDidFinishNotification
                                               object:movieplayer.moviePlayer];

    // Set the modal transition style of your choice
    movieplayer.modalTransitionStyle = UIModalTransitionStyleCrossDissolve;

    movieplayer.moviePlayer.scalingMode = MPMovieScalingModeAspectFit;

    for(UIView* subV in movieplayer.moviePlayer.view.subviews) {
        subV.backgroundColor = [UIColor clearColor];
    }


    [[movieplayer view] setBounds:CGRectMake(0, 0, 480, 320)];
    CGAffineTransform transform = CGAffineTransformMakeRotation(-M_PI/2);
    movieplayer.view.transform = transform;




    movieplayer.moviePlayer.fullscreen=YES;
    [self presentModalViewController:movieplayer animated:NO];
   self.view addSubview:movieplayer.view];

    [movieplayer.moviePlayer play];

}

- (void)movieFinishedCallback:(NSNotification*)aNotification
{
    NSNumber *finishReason = [[aNotification userInfo] objectForKey:MPMoviePlayerPlaybackDidFinishReasonUserInfoKey];


          MPMoviePlayerController *moviePlayer = [aNotification object];

        moviePlayer.fullscreen = NO;
        [movieplayer dismissModalViewControllerAnimated:NO];

        // Remove this class from the observers
        [[NSNotificationCenter defaultCenter] removeObserver:self
                                                        name:MPMoviePlayerPlaybackDidFinishNotification
                                                      object:moviePlayer];


    }

请给我一个线索。提前感谢。

我认为您需要实际聆听来自UIDevice的旋转事件，以完成您正在尝试的操作。我已经创建了一个应用程序，它有一个锁定到纵向的UILabel和一个MPMoviePlayerViewController，当设备方向改变时，它会旋转。我使用了autolayout（因为这是我最熟悉的），但在iOS5风格的自动调整大小等方面应该很容易

运行这个，让我知道你是否在追求它

以下是我在AppDelegate.m中的整个应用程序：

#import "AppDelegate.h"
#import <MediaPlayer/MediaPlayer.h>

@interface MyViewController : UIViewController
@property (nonatomic, strong) MPMoviePlayerController *player;
@end

@implementation MyViewController

- (void)loadView
{
    [super loadView];

    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(deviceOrientationDidChange:) name:UIDeviceOrientationDidChangeNotification object:nil];

    self.player = [[MPMoviePlayerController alloc] initWithContentURL:[NSURL URLWithString:@"http://techslides.com/demos/sample-videos/small.mp4"]];
    self.player.scalingMode = MPMovieScalingModeAspectFit;
    [self.player play];

    UIView *playerView = self.player.view;

    [self.view addSubview:playerView];
    playerView.translatesAutoresizingMaskIntoConstraints = NO;
    [self.view addConstraints:[NSLayoutConstraint constraintsWithVisualFormat:@"H:|[playerView]|"
                                                                      options:0
                                                                      metrics:nil
                                                                        views:NSDictionaryOfVariableBindings(playerView)]];

                                                                      metrics:nil
                                                                        views:NSDictionaryOfVariableBindings(playerView)]];

我已经试过了。但它使所有的ViewController都处于纵向和横向模式，但我只想旋转MPMovieViewController。好的，我想我现在明白你的意思了。我已经按照你说的更新了答案
