body: <p>I am using a array containing objects from two dictionaries and displaying objects of first dictionary on first cell having different identifier and same with second dictionary objects. </p>
  
  <p>check out my code in cellforrowatindexpath</p>
  
  <pre><code>static NSString *cellIdentifier = @"cellIdentifier1";
      static NSString *customCellIdentifier = @"cellIdentifiercustom";
  
      if (indexPath.row == 0) {
          UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier];
          //        if (cell==nil)
          {
              cell=[[UITableViewCell alloc]initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:cellIdentifier];
  
          }
          cell.selectionStyle = UITableViewCellSelectionStyleNone;
          ExcName = [[UILabel alloc] initWithFrame:CGRectMake(10.0, 2.0, 250.0, 36.0)];
          ExcName.font = [UIFont systemFontOfSize:12.0];
          ExcName.textColor = [UIColor blackColor];
          ExcName.textAlignment = NSTextAlignmentLeft;
          ExcName.text=[[exerciseAr objectAtIndex:indexPath.row] objectForKey:@"activityname"];
          ExcName.numberOfLines=3;
          [cell.contentView addSubview:ExcName];
  
          return  cell;
      }
      else{
          UITableViewCell *customcell = [tableView dequeueReusableCellWithIdentifier:customCellIdentifier];
  
          //        if (cell==nil)
          {
              customcell=[[UITableViewCell alloc]initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:customCellIdentifier];
  
          }
          customcell.selectionStyle = UITableViewCellSelectionStyleNone;
          ExcName = [[UILabel alloc] initWithFrame:CGRectMake(10.0, 2.0, 250.0, 36.0)];
          ExcName.font = [UIFont systemFontOfSize:12.0];
          ExcName.textColor = [UIColor blackColor];
          ExcName.textAlignment = NSTextAlignmentLeft;
          ExcName.text=[[exerciseAr objectAtIndex:indexPath.row] objectForKey:@"exercisename"];
          //    ExcName.text=[[exerciseAr objectAtIndex:indexPath.row] objectForKey:@"exercisename"];
  
          ExcName.numberOfLines=3;
          [customcell.contentView addSubview:ExcName];
  
                  return  customcell;
      }
  
      return nil;
  }
