UIModalViewController和UIImagePickerController轮换问题

Question

情况如下： 我有一个以这种方式呈现的viewController：

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

在addAttachment中有一个按钮以这种方式打开相机：

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;因此，当我解雇选择器时，addAttachment的框架错误并且旋转不正确。

换句话说，当显示相机时，其下的模态视图控制器不接收旋转，因此，当我解除拾取器时，视图控制器的框架完全错误。

...谢谢

Answer 1

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，仅为纵向方向返回YES。添加以下方法以允许自动旋转到所有方向：

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

Answer 2

您必须手动处理ViewController的旋转。

前台ViewController应该将旋转消息传播到它后面的所有ViewControllers。
