駁回圖像選擇器導致崩潰

Question

我使用未UINavigationCtronller從到的UIViewController甲一個的UIViewController B. 導航論的UIViewController B的視圖，我輕按一鍵和呼叫UIImagePicker

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

ipc.sourceType = UIImagePickerControllerSourceTypeCamera; 

ipc.delegate = self; 

ipc.allowsEditing = NO; 

[self presentModalViewController:ipc animated:YES]; 

如果我點擊'取消」 UIImagePicker的按鈕，我叫

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



[picker dismissModalViewControllerAnimated:YES]; 

}

UI將返回的UIViewController一個相當優於B

如果我點擊任何地方，應用程序崩潰。

歡迎而不是

[picker dismissModalViewControllerAnimated:YES]; 

Answer 1

任何評論嘗試

[picker.presentingViewController dismissModalViewControllerAnimated:YES]; 

你要被呈現拾取解僱，而不是選擇器本身的ViewController。
