How to definitively set UITabBar background color and tint color
提问by Harry Merzin
I have been trying to set my UITabBar's tint color and background color for quite some time now and nothing seems to work.
So far I have tried:
UITabBar一段时间以来，我一直在尝试设置我的色调和背景色，但似乎没有任何效果。到目前为止，我已经尝试过：
tabBarController?.tabBar.backgroundColor = UIColor.orangeColor()
tabBarController?.tabBar.barTintColor = UIColor.whiteColor()
as well as:
也：
UITabBar.appearance().tintColor = UIColor.orangeColor()
Neither of these seemed to have any effect on my tab bar. I'd also like to mention that I have the VC embedded in a navigation controller for which the global tint color that I set works perfectly fine.
这些似乎都对我的标签栏没有任何影响。我还想提一下，我将 VC 嵌入到导航控制器中，我为其设置的全局色调颜色非常好。

If you want to set tabbar's tint and barTint colorimplicitly then in your Appdelegate.swift,
如果您想tint and barTint color隐式设置标签栏，则在您的Appdelegate.swift,
UITabBar.appearance().barTintColor = .orange
UITabBar.appearance().tintColor = .green
If you want to set tabbar's tint and barTint colorfor specific viewController then in ViewController.swift,
如果你想tint and barTint color为特定的 viewController设置标签栏，然后在ViewController.swift，
self.tabBarController?.tabBar.tintColor = .orange
self.tabBarController?.tabBar.barTintColor = .green

Set tab bar background color with barTintColor:
使用 barTintColor设置标签栏背景颜色：
self.tabBar.barTintColor = UIColor.blueColor()
//or
UITabBar.appearance().barTintColor = UIColor.blueColor()
And for tab bar tint color:
对于标签栏色调颜色：
self.tabBar.tintColor = UIColor.whiteColor() // Selected tab color
//or
UITabBar.appearance().tintColor = UIColor.whiteColor()
