ios - 将节标题 View 添加到表

Question

我想知道我做错了什么:

-(UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section
{
    /* Table header */

    HeaderView *tableHead = [[HeaderView alloc]initWithFrame:CGRectMake(0, 0, self.myTableView.frame.size.width, 40)];
    [tableHead initialize];
    return tableHead;
}

我的 View 类很简单:

@interface  HeaderView ()

@property (nonatomic) UILabel *headerLbl;

@end

@implementation HeaderView


-(instancetype)init{

    self = [super init];
    return self;
}

-(void)initialize{

    [self createUserInterface];
    [self createConstraints];
}

-(void)createUserInterface{

    self.backgroundColor = [UIColor defaultGray];
    _headerLbl = [UILabel new];
    _headerLbl.font = [UIFont systemFontOfSize:13];
    _headerLbl.textColor = [UIColor fontGray];
    _headerLbl.numberOfLines = 0;
    [self addSubview:_headerLbl];
}



-(void)createConstraints{

    [_headerLbl mas_makeConstraints:^(MASConstraintMaker *make) {

        make.centerX.equalTo(self.mas_centerX);
        make.centerY.equalTo(self.mas_centerY);
    }];

}

该方法应该为我的表创建标题 View ，但它没有。

添加这个方法

-(CGFloat)tableView:(UITableView *)tableView heightForHeaderInSection:(NSInteger)section {
    return 40;
}
