🧭 SwiftUINavigator

轻松地在 UIKit 项目中使用 SwiftUI 视图。

🤔 为什么需要 SwiftUINavigator？

使用 UIHostingController 时，我遇到了难以预测且无法解决的错误。这就是我制作 SwiftUINavigator 来解决这些问题的原因。

⚒️ 工作原理

✔️ 简单示例

let viewController = HomeView() // View
    .asViewController() // WrapperViewController
    .title("HomeView") // UIViewController
    .backgroundColor(.gray) // UIViewController
    .hidesBottomBarWhenPushed(true) // UIViewController

weak var navigator: Navigator?
let controller = DestinationView().asViewController()
navigator.push(controller)

weak var navigator: Navigator?
let controller = DestinationView().asViewController()
navigator?.present(controller, .popover)

weak var navigator: Navigator?
navigator.pop(to: "HomeView")

weak var navigator: Navigator?
navigator.pop()

weak var navigator: Navigator?
navigator.dismiss()

✔️ 项目示例

UIKit 端

func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options connectionOptions: UIScene.ConnectionOptions) {

    guard let scene = (scene as? UIWindowScene) else { return }
    window = UIWindow(frame: scene.coordinateSpace.bounds)
    window?.windowScene = scene
    
    let controller = RootView().asViewController()
    let navigationController = UINavigationController(rootViewController: controller)
    
    window?.rootViewController = navigationController
    window?.makeKeyAndVisible()
}

SwiftUI 端

struct RootView: Wrappable {
    
    weak var navigator: Navigator?
    
    var body: some View {
        Button("Button") {
            let controller = DestinationView().asViewController()
            navigator?.push(controller)
        }
    }
}

struct DestinationView: Wrappable {
    
    weak var navigator: Navigator?
    
    var body: some View {
        Button("Button") {
            navigator?.pop()
        }
    }
}
