我的应用程序处于纵向模式 .

当视频播放器进入全屏模式时，我想以横向和纵向播放该视频 .

moviePlayer = [[MPMoviePlayerController alloc]initWithContentURL:url];
[moviePlayer.view setAutoresizingMask:(UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleWidth)];

[moviePlayer setScalingMode:MPMovieScalingModeFill];

moviePlayer.view.frame = CGRectMake(0, 0, self.videoPlayerView.frame.size.width, self.videoPlayerView.frame.size.height);
[self.videoPlayerView addSubview:moviePlayer.view];

我正在一个按钮上播放它 .

ios objective-c

    在部署信息中启用横向设备方向 . 然后，在ViewController中添加以下方法：

    - (BOOL) shouldAutorotate {
    return NO;
}

- (NSUInteger) supportedInterfaceOrientations {
    return UIInterfaceOrientationMaskPortrait;
}

- (UIInterfaceOrientation) preferredInterfaceOrientationForPresentation {
    return UIInterfaceOrientationPortrait;
}

    尝试将画布视图作为superview添加到播放器并将转换应用于画布视图 .

    - (void)initialize{    
    self.canvas = [[UIView alloc] initWithFrame: self.view.bounds];
    [self.view addSubview:self.canvas];

    // init moviePlayer
    moviePlayer = [[MPMoviePlayerController alloc]initWithContentURL:url];
    ...
    [self.canvas addSubview: moviePlayer.view];

    // Add observers
    ...
    [[NSNotificationCenter defaultCenter] addObserver: self
                     selector: @selector(deviceOrientationDidChange)
                         name: UIDeviceOrientationDidChangeNotification
                       object: nil];
    [[UIDevice currentDevice] beginGeneratingDeviceOrientationNotifications];
}

- (void)deviceOrientationDidChange{
    // Apply rotation only in full screen mode
    if (self.isFullScreen) {
        UIDeviceOrientation currentOrientation = [UIDevice currentDevice].orientation;

        [UIView animateWithDuration: 0.3 
                         animations: ^{
             CGAffineTransform transform = CGAffineTransformMakeRotation(0);
             switch (orientation) {
                 case UIDeviceOrientationLandscapeLeft:
                     transform = CGAffineTransformMakeRotation(M_PI_2);
                 break;
                 case UIDeviceOrientationLandscapeRight:
                     transform = CGAffineTransformMakeRotation(M_PI + M_PI_2);
                 break;
                 default:
                 break;
            };

            self.canvas.transform = transform;
            self.canvas.frame = self.canvas.superview.bounds;
        }];
    }
}
