本文介绍了一个iOS应用中使用系统原生播放器实现横竖屏切换的方法。通过在AppDelegate中设置允许旋转的属性，并在XRDCustomerViewController中进行相应的处理，实现了播放器在不同屏幕方向间的平滑过渡。

最近在做视屏播放，我用的系统原生的播放器，但是横竖屏切换的时候遇到问题，这里是我的解决办法，记在此处，日后查找也方便。
首先在AppDelegate中如下写：

//appdelegate.h加 
@property (nonatomic, assign) BOOL allowRotation;



//appdelegate.m加 
-(NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window

{

    if (self.allowRotation) {

        return UIInterfaceOrientationMaskPortrait |UIInterfaceOrientationMaskLandscapeLeft |UIInterfaceOrientationMaskLandscapeRight;

    }

    return UIInterfaceOrientationMaskPortrait;

}


- (NSUInteger)supportedInterfaceOrientations

{

    return UIInterfaceOrientationMaskPortrait |UIInterfaceOrientationMaskLandscapeLeft |UIInterfaceOrientationMaskLandscapeRight;

}

- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation

{

    return UIInterfaceOrientationPortrait;


}

其次，跳转方法

- (void)TapMovieTableCellDelegate:(NSString *)urlString
{
    NSURL *videoUrl = [NSURL URLWithString:urlString];

    XRDCustomerViewController *xrd = [[XRDCustomerViewController alloc] initWithContentURL:videoUrl];
    // 缓冲播放
    [xrd.moviePlayer prepareToPlay];
    // 播放
    [xrd.moviePlayer play];
    // 跳转方式
    [xrd setModalTransitionStyle:UIModalTransitionStyleCrossDissolve];
    // 弹出播放器
    [self presentMoviePlayerViewControllerAnimated:xrd];

}

最后XRDCustomerViewController.h文件:

#import <MediaPlayer/MediaPlayer.h>

@interface XRDCustomerViewController : MPMoviePlayerViewController

@end

XRDCustomerViewController.m文件:

#import "XRDCustomerViewController.h"

@implementation XRDCustomerViewController

- (void)viewWillAppear:(BOOL)animated{

    [super viewWillAppear:animated];
}

-(void)viewDidAppear:(BOOL)animated{

    [super viewDidAppear:animated];

    AppDelegate  *delegate = (AppDelegate *)[[UIApplication sharedApplication] delegate];

    delegate.allowRotation = YES;
}

- (void)viewWillDisappear:(BOOL)animated{

    AppDelegate  *delegate = (AppDelegate *)[[UIApplication sharedApplication] delegate];

    delegate.allowRotation = NO;
}

- (void)viewDidLoad
{
    [super viewDidLoad];

    // 该类继承于MPMoviePlayerViewController
}
@end
