선택한 행을 상세보기로 전달

Question

저녁,

세부보기를 구성하는 중입니다. 데이터는 plist 파일에 저장되며 각 항목에는 단어와 정의가 있습니다. 테이블 뷰의 셀에는 단어가 레이블로 지정됩니다. 단어와 정의를 모두 보여주는 세부보기로 이어지는 각 단어를 찾고 있습니다. 코드가 잘못된 단어를 표시하고 있습니다. 나는 tableview.m에 단어와 정의를 설정하려고 시도하고 이것을 사용하여 세부 사항보기에서 레이블을 설정합니다. 내 검색어가 잘못된 단어가 표시되는 이유와 그 단어와 일치하는 올바른 정의를 얻을 수있는 이유입니다.

내 코드는 다음과 같습니다. 감사합니다. 사전은 본질적으로 순서가 있기 때문에

Answer 1

당신은 alphabetizedWords라는 사전을 갖는

-(void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender{ 
    if ([segue.identifier isEqualToString:@"showDetail"]) { 
     NSIndexPath *indexPath = [self.tableView indexPathForSelectedRow]; 
     detailViewController *destViewController = segue.destinationViewController; 

     NSArray *unsortedKeys = [self.alphabetizedWords allKeys]; 
     NSArray *sortedKeys = [unsortedKeys sortedArrayUsingSelector:@selector(localizedCaseInsensitiveCompare:)]; 
     NSString *key = [sortedKeys objectAtIndex:[indexPath section]]; 
     NSArray *wordsForSection = [self.alphabetizedWords objectForKey:key]; 
     NSString *word = [wordsForSection objectAtIndex:[indexPath row]]; 
     destViewController.word = word; 

    } 
} 

Answer 2

, 당신이 cellForRowAtIndexPath에서 사용하는 워드를 얻을 수 prepareForSegue에서 같은 논리를 사용하기 위해 필요한 것은 꽤 의미가있다. 배열에서 데이터 구조를 설정해야합니다. 아마도 각 사전에 하나의 키에 단어가 있고 다른 키에 정의가 들어있는 사전 배열이 필요합니다. 배열을 정렬하고 테이블 뷰 데이터 소스에 피드를 사용하고 탭에 응답하여 정보를 상세보기 컨트롤러에 전달할 수 있습니다.
