Swift scene userActivity NSUserActivity pass tu viewController

Question

我有个问题。在“SceneDelegate类”中

func scene(_ scene: UIScene, continue userActivity: NSUserActivity) {
   let url = userActivity.webpageURL  
print(url) //result is www.mywebsite.com
}

如何将此url传递到我的ViewController？

这将取决于您拥有的视图控制器层次结构，但是假设您有一个UITapBarController作为根视图控制器，并且您希望最终获得导航控制器中的视图控制器：

func scene(_ scene: UIScene, continue userActivity: NSUserActivity) {
    let url = userActivity.webpageURL  
    if let windowScene = scene as? UIWindowScene {
        for window in windowScene.windows {
            if let rootViewController = window.rootViewController {
                let storyboard = UIStoryboard(name: "Main", bundle: nil)
                if  let yourVC = storyboard.instantiateViewController(withIdentifier: "YourVC") as? YourViewController,
                    let tabBarController = rootViewController as? UITabBarController,
                    let navController = tabBarController.selectedViewController as? UINavigationController {
                    yourVC.data = url
                    navController.pushViewController(yourVC, animated: true)
                }
            }
        }
    }
}

更新

func scene(_ scene: UIScene, continue userActivity: NSUserActivity) {
    let url = userActivity.webpageURL
    if let windowScene = scene as? UIWindowScene {
        for window in windowScene.windows {
            if let rootViewController = window.rootViewController {
                let storyboard = UIStoryboard(name: "Main", bundle: nil)
                if let yourVC = storyboard.instantiateViewController(withIdentifier: "EventViewController") as? EventViewController,
                   let navController = rootViewController as? UINavigationController {
                    yourVC.data = url
                    navController.pushViewController(yourVC, animated: true)
                }
            }
        }
    }
}
