享受…但是我建议你把你的问题说清楚…这会对你有很大帮助…如果我应该把这个代码放在table2类中，在上面找到我的代码请看，首先了解事实。您可以通过在第一个视图控制器中导入secondViewController来访问firstViewController中secondViewController的tableView，并可以获取secondViewController的table view的实例。但是，您不能通过同一个过程在第二个视图控制器中真正访问firstViewController的tableView，因为您无法导入firstViewController在这里在第二个..（因为第二个ViewController已经在第一个中导入）根本不是一个好方法…你需要在这里找到其他东西..如果我的答案对你没有用处，很抱歉。
