UIModalViewController和旋转的UIImagePickerController问题

Question

情况是这样的： 我一直认为在这种方式提出的viewController：

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

在addAttachment存在，以这种方式打开相机按钮：

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会自行旋转，但addAttachment不会旋转;所以当我解雇选择器addAttachment有一个错误的框架，它不能正常旋转。

换言之，示出了摄像机的情况下，其下的模态视图控制器，不接收旋转等等，当我关闭该选择器，视图控制器的帧是完全错误的。

谢谢...

Answer 1

您必须手动处理ViewController的旋转。

前景的ViewController应该传播转动消息的背后都ViewControllers。

Answer 2

你必须告诉AddAttachmentPhotoVideoViewController，它应该自动旋转到所有的接口方向。默认情况下，YES仅以纵向方向返回。添加以下方法以允许自动旋转到所有方向：

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