pragma mark - 以下兩個方法 是將tableview的分割線 頂頭

• (void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath{
  if([cell respondsToSelector:@selector(setSeparatorInset:)]){
  [cell setSeparatorInset:UIEdgeInsetsMake(0,70,0,10)];
  }

  if([cell respondsToSelector:@selector(setLayoutMargins:)]){
  [cell setLayoutMargins:UIEdgeInsetsMake(0,70,0,10)];
  }
  }

• (void)viewDidLayoutSubviews{
  if([_tableView respondsToSelector:@selector(setSeparatorInset:)]){
  [_tableView setSeparatorInset:UIEdgeInsetsMake(0,70,0,10)];
  }

  if([_tableView respondsToSelector:@selector(setLayoutMargins:)]){
  [_tableView setLayoutMargins:UIEdgeInsetsMake(0,70,0,10)];
  }
  }
