iPad相机popover预览错误的旋转和缩放

我在popup窗口中显示相机（在iPad上 – iPad应用程序已locking到Lanscape左侧），预览是以纵向和错误的比例显示的。 下面的代码 – 我已经制定了旋转，并添加它，但预览大小是现在太薄。

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];
