IOS-UITableView手动添加时，Header Section的背景设置

方法如下：-(UIView*) tableView:(UITableView*)tableView viewForHeaderInSection:(NSInteger)section {UIView*headerView =[[[UIView alloc] initWithFrame:CGRectMake(0,0, tableView.bounds.size.width,30)] autorelease];if(section == integerRepresentingYourSectionOfInterest)[headerView setBackgroundColor:[UIColor redColor]];else[headerView setBackgroundColor:[UIColor clearColor]];return headerView;}
