UIViewController에

Question

내가 DictAddSubSecondCell라는 UIViewController에 제시하는 다음과 같은 방법을 사용 닫으면있는 tableView를 다시로드하는 방법 : 나는 DictAddSubSecondCell에서 버튼을 클릭하면

// UIViewControler 1 
- (IBAction)addWord:(id)sender{ 
dictAddSubSecondCellController = [[DictAddSubSecondCell alloc] initWithNibName:@"DictAddSubSecondCell" bundle:nil]; 
[self presentModalViewController:dictAddSubSecondCellController animated:YES]; 
[dictAddSubSecondCellController release]; 
} 

을과 :

- (IBAction)dismissAction:(id)sender{ 
[self dismissModalViewControllerAnimated:YES]; 
} 

UIViewControler에있는 tableView 1은 데이터를 다시로드하지 않았지만 viewWillApear 메서드에 메서드를 추가했습니다.

[self.table reloadData]; 

하지만 여전히 작동하지 않습니다. 나는 이것에 대해 전혀 모른다. 저에게 어떤 제안이 있습니까? 감사.

이 viewDidAppear: 대신 viewWillAppear:에 전화하십시오 :
