将UIImagePickerController移动到一个单独的类中

我一直试图解决与this question完全相同的问题一段时间,但我遇到了麻烦。我几个月才在XCode上工作,所以非常感谢帮助。

在我的父母VC.m中我有这个:

parentVC.m

- (IBAction)goToCamera:(id)sender {
     [_camera takePhoto];
     } return;
  }

这在相当于James的PhotoManager类中调用takePhoto方法:一个名为Camera的NSObject类 - 我在其中设置了UIImagePickerController。我在标题中说明了方法:

Camera.h

- (void) takePhoto;

然后在实施中:

Camera.m

@class ParentVC;
@interface Camera () <UIImagePickerControllerDelgate, UINavigationControllerDelegate>
@property (nonatomic, retain) ParentVC *parentVC;
@end
@implementation Camera

-(void)takePhoto
{
    if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera])
    {
        UIImagePickerController *cameraUI = [[UIImagePickerController alloc] init];
        cameraUI.sourceType = UIImagePickerControllerSourceTypeCamera;
        cameraUI.delegate = self;
        [_parentVC presentViewController:cameraUI animated:NO completion:nil];
    }
    else{
        DLog(@"camera wouldn't load");
        }
    }
@end

没有运气。我尝试了很多迭代,但无法弄清楚。有什么想法吗?
