当视图被锁定为横向模式时，UIPopoverController内的UIImagePickerController在纵向模式下

Question

我正在使用以下代码在iPad中打开弹出视图控制器中的摄像头。一切都很好，除了它始终以横向模式打开。我想在横向模式下打开pop相机。父视图被锁定为横向模式。
请让我知道是否可以将相机框架尺寸更改为纵向模式。

UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init];
imagePicker.sourceType = UIImagePickerControllerSourceTypeCamera;
imagePicker.cameraDevice = UIImagePickerControllerCameraDeviceFront;
imagePicker.delegate = self;
UIPopoverController *popover = [[UIPopoverController alloc] initWithContentViewController:imagePicker];
self.popOverController = popover;
popover.popoverContentSize = CGSizeMake(350, 500);
popover.delegate = self;
[self.popOverController presentPopoverFromRect:CGRectMake(100, 100, 350,500) inView:self permittedArrowDirections:UIPopoverArrowDirectionLeft animated:YES];

Answer 1

你可以使用Subclassing UIImagePickerController

来做到这一点

 @interface UAImagePickerController : UIImagePickerController {
}
@end

@implementation UAImagePickerController
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation {
    return UIDeviceOrientationIsPortrait(toInterfaceOrientation);
}
@end
