Question

我有一个完整工作的分组tableview。但是，当我只是点击一个单元格时 - 没有任何反应。 willSelectRowAtIndexPath甚至没有被调用。所有插座都设置正确，userInteractions已启用，tableView是页面上唯一的视图。谷歌搜索几个小时都没有成功。每个人都有一个从开始的选择功能，有人甚至试图摆脱它。求助。

代码（坏的，我知道）：

Answer 1

您是否在UITableView代表中实施了类似的内容？

- (BOOL)tableView:(UITableView *)tableView willSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    return NO;
}

抱歉，错误的假设和编译器警告被忽略了......

这不是解决方案。

Answer 2

我做了一些实验，在isUserInteractionEnabled UITableView祖先上找到了属性View。如果设置为NO，则禁用单元格选择（与任何其他交互一样）。在这种情况下，无法上下移动视图单元格。

UITableView不会对点击做出反应
