自定义UITabBar未选择项目的颜色

Question

我试图更改未选中的UITabBarItems的默认灰色.我设法改变了文本而不是图像.

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)

Answer 1

iOS 10 | 斯威夫特3

class TabBarVC: UITabBarController {

    override func viewDidLoad() {
        super.viewDidLoad()

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

Answer 2

您可以使用 .AlwaysOriginal

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