如何definitiveley设置UITabBar背景颜色和UITabBar色彩 [英] How to definitiveley set UITabBar background color and UITabBar tint color

问题描述

我一直试图将UITabBar的色彩和背景颜色设置好一段时间，似乎没有任何效果。
到目前为止，我尝试过：

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:

tabBarController?.tabBar.backgroundColor = UIColor.orangeColor()
tabBarController?.tabBar.barTintColor = UIColor.whiteColor()

以及：

UITabBar.appearance().tintColor = UIColor.orangeColor()

这些似乎都没有对我的标签栏产生任何影响。我还想提一下，我在导航控制器中嵌入了VC，我设置的全局色调颜色完全正常。

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.

推荐答案

如果你想隐式设置tabbar的色调和barTint颜色然后在你的 Appdelegate.swift 中，

If you want to set tabbar's tint and barTint color implicitly then in your Appdelegate.swift,

    UITabBar.appearance().barTintColor = UIColor.orangeColor()
    UITabBar.appearance().tintColor = UIColor.greenColor()

如果你想设置tabbar的色调和barTint颜色对于特定的viewController然后在 ViewController.swift ，

If you want to set tabbar's tint and barTint color for specific viewController then in ViewController.swift,

 self.tabBarController?.tabBar.tintColor = UIColor.orangeColor()
 self.tabBarController?.tabBar.barTintColor = UIColor.greenColor()
