Custom UITabBar unselected item's color

问题

I am trying to change the default grey colour of the unselected UITabBarItems. I have managed to change the text but not the image.

TabBar.appearance().barTintColor = UIColor(red: 86.0/255.0, green: 132.0/255.0, blue: 208.0/255.0, alpha: 1.0)

var normalTint: UIColor = UIColor.whiteColor()

TabBar.appearance().tintColor = UIColor.whiteColor()

UITabBarItem.appearance().setTitleTextAttributes([NSForegroundColorAttributeName: normalTint,NSFontAttributeName: UIFont(name: "Arial", size: 13)!], forState: UIControlState.Normal)

回答1:

you can use .AlwaysOriginal

tabBarItem.selectedImage = UIImage(named: "first-selected")!.imageWithRenderingMode(.AlwaysOriginal)

iOS 10 | Swift 3

class TabBarVC: UITabBarController {

    override func viewDidLoad() {
        super.viewDidLoad()

        // make unselected icons white
        self.tabBar.unselectedItemTintColor = UIColor.white
    }
}

• If you want to set unselected icons to specific color through Storyboard.
• You can do it through 'User defined runtime attributes', without adding the codes.
