//自定义Header视图

- (nullable UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section{

    if (section == 0) {

        UIView *view = [[UIViewalloc]init];

        imageViews.image = [UIImageimageNamed:@"help_basic"];

        [view addSubview:imageViews];

        

        UILabel *label1=[[UILabelalloc]initWithFrame:CGRectMake(50,30, KYRect.size.width-20,25)];

        //label1.layer.borderWidth = 1;

       // label1.layer.borderColor = [[UIColor blackColor]CGColor];

        label1.textAlignment =NSTextAlignmentLeft;

        label1.text=@"基本信息";

        label1.font = [UIFontboldSystemFontOfSize:23.0f];

        

        UIView *line = [[UIViewalloc]initWithFrame:CGRectMake(0,69, KYRect.size.width,1)];
