我有一个带有 TabBar 的 SwiftUI 应用程序。如果我从 NavigationView 打开详细信息子视图,然后单击“后退”,TabBar 将变为透明,显示 TabBar 图标下方的 Feed 中的项目。

这就是我需要做的一切。
if #available(iOS 15.0, *) {
let tabBarAppearance = UITabBarAppearance()
tabBarAppearance.configureWithDefaultBackground()
UITabBar.appearance().scrollEdgeAppearance = tabBarAppearance
}

在iOS 15中,Apple将对scrollEdgeAppearance的支持扩展到UIKit。默认情况下,此设置会生成透明的 TabBar 背景。
要解决此问题,请将以下代码添加到您的 SceneDelegate 文件中,以定义 TabBar 的颜色,这样 SwiftUI 就不会自动使其透明。
class SceneDelegate: UIResponder, UIWindowSceneDelegate {
var window: UIWindow?
func scene(
_ scene: UIScene,
willConnectTo session: UISceneSession,
options connectionOptions: UIScene.ConnectionOptions
) {
guard let windowScene = (scene as? UIWindowScene) else { return }
// MARK: ADD THIS CODE BELOW TO YOUR SCENE DELEGATE.
// TAB BAR BACKGROUND COLOR HERE.
UITabBar.appearance().barTintColor = UIColor.white
// TAB BAR ICONS COLOR HERE.
UITabBar.appearance().tintColor = UIColor.blue
UITabBar.appearance().isTranslucent = true
if #available(iOS 15.0, *) {
let appearance = UITabBarAppearance()
appearance.configureWithOpaqueBackground()
// TAB BAR BACKGROUND COLOR HERE. (same as above)
appearance.backgroundColor = UIColor.white
UITabBar.appearance().standardAppearance = appearance
UITabBar.appearance().scrollEdgeAppearance = UITabBar.appearance().standardAppearance
}
let window = UIWindow(windowScene: windowScene)
window.rootViewController = UIHostingController(rootView: RootView())
self.window = window
window.makeKeyAndVisible()
}
}
