UIImagePickerController allowEditing = YES不起作用

Question

- (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex {
UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init];
imagePicker.delegate = self;
imagePicker.allowsEditing = YES;

switch (buttonIndex) {
    case 0:
    {
        imagePicker.sourceType = UIImagePickerControllerSourceTypeCamera;
        imagePicker.cameraDevice = UIImagePickerControllerCameraDeviceFront;
        [self presentViewController:imagePicker animated:YES completion:nil];
    }
        break;
    case 1:
    {
        imagePicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
        [self presentViewController:imagePicker animated:YES completion:nil];
    }
        break;
    case 2:
    {
        [actionSheet removeFromSuperview];
    }
            break;
        default:
            break;
    }
}

拍照時無法拖動照片，但是UIImagePickerControllerSourceTypePhotoLibrary中的照片可以編輯

試試這個代碼。 它可以在前后攝像頭模式下為我工作。

UIImagePickerController * imagePicker = [[UIImagePickerController alloc] init]; imagePicker.delegate =自我;

    if (buttonIndex==0) {
        if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]) {
            imagePicker.sourceType = UIImagePickerControllerSourceTypeCamera;
            imagePicker.mediaTypes = @[(NSString *) kUTTypeImage];
            imagePicker.allowsEditing = YES;
            [self presentViewController:imagePicker animated:YES completion:nil];

        }

    }
