iOS13 - UITabBar未选中项目的tintColor不起作用

Question

在Xcode 10中，unselectedItemTintColor属性正常工作，但在Xcode 11和iOS 13中，UITabbar的unselectedItemTintColor属性不起作用。

override func viewDidLoad() {
    super.viewDidLoad()

    myTabbar.unselectedItemTintColor = .red
}

iOS 13+的情况下，请参考以下代码：if #available(iOS 13.0, *) { let statusBar = UIView(frame: UIApplication.shared.keyWindow?.windowScene?.statusBarManager?.statusBarFrame ?? CGRect.zero) statusBar.backgroundColor = UIColor.red // Set any desired color UIApplication.shared.keyWindow?.addSubview(statusBar) }这将在iOS 13及更高版本中创建一个自定义状态栏，并将其添加到应用程序窗口中。请注意，此代码仅适用于使用Swift编写的应用程序。 - Keshu R.

尝试这个：self.tabBar.unselectedItemTintColor = [UIColor lightGrayColor]; - Mayank

这个回答解决了你的问题吗？在Xcode 11 beta 2中，当在Interface Builder中指定了一个栏色调颜色时，UITabBarItem图标在iOS 13上没有正确着色。 - Jawad Ali

iOS 13与Xcode 11

if #available(iOS 13, *) {
     let appearance = UITabBarAppearance()
     appearance.stackedLayoutAppearance.normal.titleTextAttributes = [NSAttributedString.Key.foregroundColor: UIColor.black]
     appearance.stackedLayoutAppearance.selected.titleTextAttributes = [NSAttributedString.Key.foregroundColor: UIColor.red]
     appearance.stackedLayoutAppearance.normal.iconColor = UIColor.black
     appearance.stackedLayoutAppearance.selected.iconColor = UIColor.red
     myTabbar.standardAppearance = appearance
}

注意：如果您正在使用内联布局（例如在iPad上），则需要使用inlineLayoutAppearance而不是stackedLayoutAppearance。 - Tad

如果您在使用inlineLayoutAppearance时遇到标题被截断的情况，请查看此问题：https://dev59.com/h8Lra4cB1Zd3GeqPEjhA#69457332 - Tad

如果遇到：iOS 15 和 Xcode 13

if #available(iOS 15, *) {
    let tabBarAppearance = UITabBarAppearance()
    tabBarAppearance.backgroundColor = .white
    tabBarAppearance.stackedLayoutAppearance.selected.titleTextAttributes = [.foregroundColor: UIColor.red]
    tabBarAppearance.stackedLayoutAppearance.normal.titleTextAttributes = [.foregroundColor: UIColor.black]
    tabBarAppearance.stackedLayoutAppearance.normal.iconColor = UIColor.black
    tabBarAppearance.stackedLayoutAppearance.selected.iconColor = UIColor.red
    tabBarView.standardAppearance = tabBarAppearance
    tabBarView.scrollEdgeAppearance = tabBarAppearance
}
