Your code has a bug when add a section view to tableView

[zhaishuai]

Add this code to your viewController

• (CGFloat)tableView:(UITableView *)tableView heightForHeaderInSection:(NSInteger)section{
  return 50;
  }
• (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section{
  UIView *view = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 360, 50)];
  view.backgroundColor = [UIColor redColor];
  return view;
  }
  You will find the bug,I hope you can fix it! thanks
