Ipad UIModalViewController和UIImagePickerController旋转问题

情况就是这样： 我有一个viewController，它是这样显示的：

AddAttachmentPhotoVideoViewController * addAttachment = [[AddAttachmentPhotoVideoViewController alloc]initWithNibName:nil bundle:nil attachmentType:AtImage];
addAttachment.modalPresentationStyle = UIModalPresentationFormSheet;
addAttachment.modalTransitionStyle = UIModalTransitionStyleCoverVertical;
            
[self presentModalViewController:addAttachment animated:YES];

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

imagePicker.delegate = self;
imagePicker.sourceType = UIImagePickerControllerSourceTypeCamera;    
imagePicker.mediaTypes = [NSArray arrayWithObjects:(NSString *) kUTTypeImage, nil];
imagePicker.allowsEditing = NO;
imagePicker.showsCameraControls = YES;
imagePicker.modalPresentationStyle = UIModalPresentationFullScreen;
imagePicker.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;
[self presentModalViewController:imagePicker animated:YES];

在

addAttachment

中，有一个按钮可以通过以下方式打开相机：

AddAttachmentPhotoVideoViewController * addAttachment = [[AddAttachmentPhotoVideoViewController alloc]initWithNibName:nil bundle:nil attachmentType:AtImage];
addAttachment.modalPresentationStyle = UIModalPresentationFormSheet;
addAttachment.modalTransitionStyle = UIModalTransitionStyleCoverVertical;
            
[self presentModalViewController:addAttachment animated:YES];

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

imagePicker.delegate = self;
imagePicker.sourceType = UIImagePickerControllerSourceTypeCamera;    
imagePicker.mediaTypes = [NSArray arrayWithObjects:(NSString *) kUTTypeImage, nil];
imagePicker.allowsEditing = NO;
imagePicker.showsCameraControls = YES;
imagePicker.modalPresentationStyle = UIModalPresentationFullScreen;
imagePicker.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;
[self presentModalViewController:imagePicker animated:YES];

问题如下：当我旋转设备（iPad）时，

imagePicker

会自动旋转，但

addAttachment

不会旋转；因此，当我关闭选择器时，

addAttachment

的帧错误，并且旋转不正确

换句话说，当显示摄影机时，其下的模态视图控制器不接收旋转，因此，当我关闭选择器时，视图控制器的帧完全错误

谢谢…

您必须告诉

AddAttachmentPhotoVideoViewController

它应该自动旋转到所有界面方向。默认情况下，

YES

仅针对纵向方向返回。添加以下方法以允许对所有方向进行自动旋转：

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    return YES;
}

必须手动处理ViewController的旋转

前台ViewController应将旋转消息传播到其后面的所有ViewController。

Hi MaTTP，您能提供一些代码片段来说明解决方案吗？谢谢您好，MaTTP，您能提供一些代码片段来说明解决方案吗？谢谢
