Swift：重新加载视图控制器 [英] Swift: Reload a View Controller

问题描述

点击某个按钮时，我需要刷新视图控制器。简单地激活 viewDidLoad（）似乎不适用于我需要做的事情。但是，当我离开视图控制器然后回到它，它似乎完美无缺？

I need to refresh a view controller when a certain button is tapped. Simply activating viewDidLoad() does not seem to be working for what I need to do. However, when I leave the view controller then come back to it, it seems to work perfectly?

怎么能我刷新/重新加载一个视图控制器就像我离开它然后回到它而没有真正离开它？

How can I refresh/reload a view controller as if I have left it then come back to it without ever actually leaving it?

推荐答案

无论您在 viewDidLoad 中编写什么代码，请尝试在 viewWillappear（）中添加。我想这会解决你的问题。

Whatever code you are writing in viewDidLoad, try to add that in viewWillappear(). I think this will solve your problem.
