Ios 我为什么从另一个视图控制器调用时，我的表视图为零？

当用户通过将表视图中的标签设置为“ONLY MEMBER”注销时，我试图从左侧菜单（滑出）重新加载我的表视图控制器。因此，我调用了refreshAuctionLatestViewController.ViewWillDisplay（true）。但是，将在该方法中重新加载的表视图为零。有帮助吗

这是我的幻灯片菜单控制器（SlideMenu）

这是我的控制台输出，您将在下面看到nil

有什么想法？有什么建议吗？我为我的问题留下了评论。希望这有助于更新该菜单，您必须调用使用该表视图的类的方法，为此，您需要做一件事， 将该类的对象创建到要更新的其他类中，然后通过该调用创建该类的方法，如

[幻灯片视图将显示：是]

这里silderpage是菜单页的一个对象

我希望这对你完全有帮助……

嗯，如果你不介意的话，请用swift解释，因为我不知道你说了什么。从你的解释来看，我用AuctionLatestViewController初始化了ActionLatestController和AuctionLatestViewController（见左菜单控制器顶部）。我这样调用了view controller类当用户点击“注销”时，在左侧菜单控制器上显示“self.refreshActionLatestController？.viewwillbeen（true）”。因此，这也不能解决问题。我更新了代码抱歉，我不太了解swift
