Currently in Xcode 8.3.2 you can do it inside the storyboard using an image that will represent the actual background.

Select the tab bar inside your tab bar controller:

<a href="https://i.stack.imgur.com/X3rPz.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/X3rPz.png" alt="enter image description here"></a>

Inside the Utilities choose the Attributes Inspector and change the selection background image:

<a href="https://i.stack.imgur.com/Psw50.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/Psw50.png" alt="enter image description here"></a>

I would like a different background color when the user selects a tab bar item than when it is unselected.

How do I change background color of UITabItem when item is selected

Swift

当用户选择选项卡栏项目时，我想要不同的背景颜色，而不是取消选择。
