如何使用Obejctive C在tableview單元格中搜索特定值時獲取所有數組值？

Question

我已經實現了一個帶有兩個標籤的自定義單元格的TableView來填充城市名稱和城市ID（我保持城市ID標籤隱藏）。在這裏，我的問題是當我搜索城市名稱時，我也無法獲得城市ID，當我搜索城市名稱時，我希望這兩個值都被過濾。

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath 
    { 
    static NSString *cellidentifier=@"citylocation"; 
     searchTableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellidentifier]; 
     if (!cell) { 
      cell= [[searchTableViewCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellidentifier]; 
     } 
     if(!isFilltered) 
     { 
      cell.textLabel.text = [avahotel objectAtIndex:indexPath.row]; 
      cell.city.text = [[createdDate objectAtIndex:indexPath.row]stringValue]; 
     }else 
     { 
      cell.textLabel.text = [filteredString objectAtIndex:indexPath.row]; 
    }  
    return cell; 
} 
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section 
{ 
    if(isFilltered) 
    { 
     return [filteredString count]; 
    } 
    return [avahotel count]; 
} 
-(void)searchBar:(UISearchBar *)searchBar textDidChange:(NSString *)searchText 
{ 
    if(searchText.length == 0) 
    { 
     isFilltered = NO; 
    }else 
    { 
     isFilltered = YES; 
     filteredString = [[NSMutableArray alloc]init]; 
     for(NSString *str in avahotel) 
     { 
      NSRange stringRange = [str rangeOfString:searchText options:NSCaseInsensitiveSearch]; 

      if(stringRange.location != NSNotFound) 
      { 
       [filteredString addObject:str]; 
      } 
     } 
    } 
    [_searchtableview reloadData]; 
}

在該方法的其他部分使用以下代碼。搜索欄textDidChange

更新

isFilltered = YES; 
    filteredString = [[NSMutableArray alloc]init]; 
    filteredCityId = [[NSMutableArray alloc]init]; 

    for(Int i=0; i<avahotel.count; i++) 
    { 
     NSString *str = [avahotel objectAtIndex:i]; 
     NSRange stringRange = [str rangeOfString:searchText options:NSCaseInsensitiveSearch]; 

     if(stringRange.location != NSNotFound) 
     { 
      [filteredString addObject:[avahotel objectAtIndex:i]]; 
      NSString *strId = [NSString stringWithFormat:@"%d",i]; 
      [filteredCityId addObject:strId] 

      // here your both filter array declare.filteredcityId and filteredString   
     } 
    }
