ios - iPad 相机弹出窗口预览错误的旋转和缩放

Question

我在弹出窗口中显示相机(在 iPad 上 - iPad 应用程序被锁定为 Lanscape Left)，并且预览为纵向且比例错误。代码如下 - 我已经计算出旋转并添加了它，但预览尺寸现在太细了。

   UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init];

   if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera])
   {
    imagePicker.sourceType = UIImagePickerControllerSourceTypeCamera;
    imagePicker.videoQuality = UIImagePickerControllerQualityTypeMedium;
    imagePicker.mediaTypes = [UIImagePickerController availableMediaTypesForSourceType:UIImagePickerControllerSourceTypeCamera];

    CGAffineTransform transformRotation = CGAffineTransformMakeRotation(270 * M_PI/180);

    imagePicker.cameraViewTransform = transformRotation;
    }
    else
    {
       NSLog(@"Camera not available. Using photo library");
       imagePicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
    }

     imagePicker.delegate = self;
     _photoPopover = [[UIPopoverController alloc] initWithContentViewController:imagePicker];
     [_photoPopover presentPopoverFromRect:view.frame inView:self.view permittedArrowDirections:UIPopoverArrowDirectionUp animated:YES];

事实证明这是 iOS 6.0 处理旋转方式的问题 - 已在 6.1 中修复
