1.首先项目允许旋转

2.在AppDeleGate里面添加监听

// 播放器即将播放通知
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(videoStarted:) name:@"UIMoviePlayerControllerDidEnterFullscreenNotification" object:nil];
    // 播放器即将退出通知
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(videoFinished:) name:@"UIMoviePlayerControllerDidExitFullscreenNotification" object:nil];

3.设置AppDelegate属性和方法

//AppDelegate.h
{
    BOOL _isFull; // 是否全屏
}
@property (nonatomic)BOOL isFull;

//AppDelegate.m
- (NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window {
    
    if(_isFull){
    return UIInterfaceOrientationMaskLandscape;
    }
    return UIInterfaceOrientationMaskPortrait;
}

4.在需要旋转的界面

- (void)ZJVideoPlayerView_isFullScreen:(BOOL)isFullScreen{
 
    if (isFullScreen) {
        [[NSNotificationCenter defaultCenter]postNotificationName:@"UIMoviePlayerControllerDidEnterFullscreenNotification" object:nil];
        [self rotateScreen:isFullScreen];
        self.videoPlayerView.sd_layout
        .topSpaceToView(self.view, 0)
        .leftSpaceToView(self.view, 0)
        .rightSpaceToView(self.view, 0)
        .heightIs(self.view.width / 16 * 9);
        [self.videoPlayerView updateLayout];
        
        [self.view bringSubviewToFront:self.videoPlayerView ];
    }else{
        
        [[NSNotificationCenter defaultCenter]postNotificationName:@"UIMoviePlayerControllerDidExitFullscreenNotification" object:nil];
        [self rotateScreen:isFullScreen];
        self.videoPlayerView.sd_layout
        .topSpaceToView(self.view, 64)
        .leftSpaceToView(self.view, 0)
        .rightSpaceToView(self.view, 0)
        .heightIs(self.view.width / 16 * 9);
        [self.videoPlayerView updateLayout];
        [self.view sendSubviewToBack:self.videoPlayerView];
    }
}
//旋转界面
- (void)rotateScreen:(BOOL)isLandscapeRight
{
    if ([[UIDevice currentDevice] respondsToSelector:@selector(setOrientation:)])
    {
        NSNumber *num = [[NSNumber alloc] initWithInt:(isLandscapeRight?UIInterfaceOrientationLandscapeRight:UIInterfaceOrientationPortrait)];
        [[UIDevice currentDevice] performSelector:@selector(setOrientation:) withObject:(id)num];
        [UIViewController attemptRotationToDeviceOrientation];
        //这行代码是关键
    }
    SEL selector=NSSelectorFromString(@"setOrientation:");
    NSInvocation *invocation =[NSInvocation invocationWithMethodSignature:[UIDevice instanceMethodSignatureForSelector:selector]];
    [invocation setSelector:selector];
    [invocation setTarget:[UIDevice currentDevice]];
    int val =isLandscapeRight?UIInterfaceOrientationLandscapeRight:UIInterfaceOrientationPortrait;
    [invocation setArgument:&val atIndex:2];
    [invocation invoke];
    [[UIApplication sharedApplication] setStatusBarHidden:isLandscapeRight withAnimation:UIStatusBarAnimationSlide];
}
