Ios -[EdgeAnalyticPageView_Cell_Selector didSelectItem:数据源：]：无法识别的选择器发送到实例0x7fc6f314fef0

使用UItables设置设置菜单。出于某种原因，“[\u listener didSelectItem:indexPath dataSource:self]”正在引发异常“无法识别的选择器发送到实例”。很难理解为什么会发生这种情况。 任何指点都将不胜感激

它缺少

EdgeAnalyticPageView\u单元格的代码，可能还缺少调用
setupWithTitle:items:multiSelect:extraData:listener
。您是否有警告说它不是
CCSelectorViewControllerListener
，或者它缺少一些委托方法，如
didSelectItem:dataSource:
，或者如果它是可选的，则没有警告……我根据要求提供了进一步的信息。非常感谢您的帮助。哪里被称为
-（void）setupWithTitle:（NSString*）title items:（NSArray*）items multiSelect:（BOOL）multiSelect extraData:（NSDictionary*））extraData listener:（id）listener{
？哪里设置了
listener
？@Lame感谢您的帮助。您能再清楚一点吗？我不确定我是否完全理解。。。
