Enable TabBar Item in View Controller from Another in Swift
Question
So I'm new to Xcode and Swift. I'm using the Xcode Beta with Swift 4.
I have two views with a tab bar, and I have the tab bar item on the second view disabled.
I'm wondering if there is anyway that on a button click in the view #1, I can enabled the tab bar item in view #2. Any help is appreciated!

在子控制器中保留tabBarController的引用，并使用那里的索引启用/禁用tabbar项，例如：
self.tabBarController!.tabBar.items![0].enabled = false
