的tableview没有看到标题为标题在第方法

Question

我试图创建一个自定义viewForHeaderInSection我tableview.Tableview本身 工作正常，但由于某些原因，编译器跳过，

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

代表法，我尝试了参考文献上的内容，但是由于某些原因，它只是不会读取这些方法。显然，我做错了什么。如果有人能指出我的错误，我将不胜感激。先谢谢你。

你需要确保实现该委托方法的类是delegate和你的表视图dataSource。
