驳回图像选择器导致崩溃

Question

我使用未UINavigationCtronller从到的UIViewController甲一个的UIViewController B. 导航论的UIViewController B的视图，我轻按一键和呼叫UIImagePicker

UIImagePickerController *ipc = [[UIImagePickerController alloc] init]; 

ipc.sourceType = UIImagePickerControllerSourceTypeCamera; 

ipc.delegate = self; 

ipc.allowsEditing = NO; 

[self presentModalViewController:ipc animated:YES]; 

如果我点击'取消” UIImagePicker的按钮，我叫

-(void)imagePickerControllerDidCancel:(UIImagePickerController*)picker{ 



[picker dismissModalViewControllerAnimated:YES]; 

}

UI将返回的UIViewController一个相当优于B

如果我点击任何地方，应用程序崩溃。

欢迎而不是

[picker dismissModalViewControllerAnimated:YES]; 

Answer 1

任何评论尝试

[picker.presentingViewController dismissModalViewControllerAnimated:YES]; 

你要被呈现拾取解雇，而不是选择器本身的ViewController。
