UIImagePickerController委托警告

Question

我刚刚把一个照片选取器放到我的项目中，并且一切正常。唯一的一点是它硬要给我下面的警告，我设定的委托 -

Assigning to 'id<UINavigationControllerDelegate,UIImagePickerDelegate>' from incompatible type 'AddTargetViewController *' 

我都以正常的方式建立委托的AddTargetViewController.h -

@interface AddTargetViewController : UIViewController <UIImagePickerControllerDelegate> 

和我看不到任何错误。正如我所说，它工作正常，并且所有的委托方法都应该发挥作用。

-(void)takePhoto { 

    UIImagePickerController *imagePicker = [[[UIImagePickerController alloc] init] autorelease]; 

    imagePicker.delegate = self; // *** warning on this line *** 
    imagePicker.sourceType = UIImagePickerControllerSourceTypeCamera; 
    imagePicker.cameraCaptureMode = UIImagePickerControllerCameraCaptureModePhoto; 

    [self presentModalViewController:imagePicker animated:YES]; 

} 

感谢您的帮助！

Answer 1

这是iPhone - UIImagePickerControllerDelegate inheritance的重复问题。

总之您的视图控制器具有符合UINavigationControllerDelegate除了UIImagePickerDelegate。

Answer 2

与您的UIImagePickerControllerDelegate一起，只需在您的.h文件中添加UINavigationControllerDelegate，它应该可以正常工作。
