Ios UITableView调用另一个UITableView单元格forrowatinexpath

我有两个带tableview的UIViewController。当第一个单元格加载到第二个UIViewController中时，它调用同一类中的CellForRowatineXpath，但当它加载第二个单元格时，它调用第一个ViewController CellForRowatineXpath

我的代码如下：

第二视图控制器：

FirstViewController：

提前谢谢。

首先，我要为这个愚蠢的问题道歉。

问题是由@Paulw11、@Onik IV、@Kannan Vora指定的tableview数据源造成的。secondViewController tableView的数据源为firstViewController。

那么，您的问题是什么？除非您更改了tableView的数据源，否则它不太可能调用其他类方法。你到底看到了什么行为？你是否设置了一个断点来确认你声称的行为？tableView在数以百万计的应用程序中使用，因此不太可能存在您所描述的bug。问题一定出在dataSource委托中，如果您是通过代码创建这两个tableView，请将代码放在这里以帮助您。如果要在脚本中创建，请确保每个tableView的数据源都是其viewController。请确保已设置正确tableView的dataSource属性
