Question

我是ios开发的新手。我在Storyboard中创建应用程序，最初是 UItableviewController，带有一个原型单元，带有按钮和标签。按钮在 UItableViewCell 类中有 IBAction 方法，该类有委托到 UItableviewController ，委托方法未调用。但截面视图中的图像是更改。我在这里发布我的完整代码。

您必须添加此行 [HeaderView setHeaderDelegate：self]; 在方法中： - （UIView *）tableView：（UITableView *）tableView viewForHeaderInSection：（NSInteger）section;

UITableView部分标题可单击代表未调用
