사전에서 배열로 검색 막대

검색 바를 구현하려고하지만 몇 가지 문제가 있습니다. 내 Tableview의 데이터는 PLIST에서 제공되며 NSMutableArray에 채워집니다. 내 PLIST는 이와 같이 보이며 NSLOG로 배열의 데이터를 볼 수도 있습니다. 이제 tableview에 검색 기능을 제공하여 "name"을 검색 할 수 있고 입력 한 이름에 맞는 모든 항목을 검색 할 수 있습니다. 하지만 내 검색이 모든 "이름"항목을 검색 할 수있게하려면 어떻게해야합니까?사전에서 배열로 검색 막대

업데이트 : 검색 필드에 입력을 시작하면 배열이 비어 있습니다.

- (void)filterContentForSearchText:(NSString*)searchText scope:(NSString*)scope 
{ 
    NSPredicate *resultPredicate = [NSPredicate 
            predicateWithFormat:@"name contains[c] %@", 
            searchText]; 

    NSMutableArray *filtered = [myArray filteredArrayUsingPredicate:resultPredicate]; 

    NSLog(@"%@", filtered); 
} 

#pragma mark - UISearchDisplayController delegate methods 
-(BOOL)searchDisplayController:(UISearchDisplayController *)controller 
shouldReloadTableForSearchString:(NSString *)searchString 
{ 
    [self filterContentForSearchText:searchString 
           scope:[[self.searchDisplayController.searchBar scopeButtonTitles] 
             objectAtIndex:[self.searchDisplayController.searchBar 
                selectedScopeButtonIndex]]]; 

    return YES; 
}

나는 이런 식으로 내있는 tableview에 데이터를 채 웁니다

cell.textLabel.text = [[[[myArray objectAtIndex:indexPath.section]objectForKey:@"Rows"]objectAtIndex:indexPath.row]objectForKey:@"name"];

상관 없음 PLIST는 다음과 같습니다.

NSPredicate을 사용할 수 있습니다.

NSPredicate *predicate = [NSPredicate predicateWithFormat: @"name contains[c] %@", stringFromSearchField];

을 그리고 당신은 다음과 같은 방법으로 배열을 필터링 얻을 수 있습니다 :

나는 다음과 같은 제안

NSMutableArray *rows = [NSMutableArray array]; 
for(NSDictionary *dict in myArray) 
{ 
    NSArray *tempRows = dict[@"Rows"]; 
    if([tempRows isKindOfClass: [NSArray class]] && tempRows.count) 
    { 
     [rows addObjectsFromArray:tempRows]; 
    } 
} 
NSArray *filteredArray = [rows filteredArrayUsingPredicate: predicate];

아주 잘 작동합니다. 많은 감사합니다. 결과가 올바르게 표시됩니다. 검색 결과에 셀의 detailtext도 표시 할 수 있습니까? 이 방법을 사용하여 하위 이름의 이름을 표시합니다. if (tableView == self.searchDisplayController.searchResultsTableView) { cell.textLabel.text = [[filtersArray objectAtIndex : indexPath.row] objectForKey : @ "name"] ; cell.detailTextLabel.text = [[filteredArray objectAtIndex : indexPath.row] objectForKey : @ "subname"]; NSLog (@ "% @", [[필터링 된 objectAtIndex : indexPath.row] objectForKey : @ "하위 이름"]); } – halloway4b
