Question

我正在尝试为viewForHeaderInSection本身创建自定义tableview.Tableview 工作正常，但由于某种原因，编译器跳过，

-(NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section{}

委托方法，我尝试了在引用上写的内容，而这个。但由于某种原因它只是不读取这些方法。显然，我做错了什么。如果有人可以指出我的错误，我将不胜感激。提前谢谢。

您需要确保实现该委托方法的类是表视图的delegate和dataSource。

tableview没有在section方法中看到header的标题
