不会调用方法'scene(_:openURLContexts :)' [英] Method 'scene(_:openURLContexts:)' is not called

问题描述

在info.plist文件中，我成功配置了URL Identifier和URL Scheme.我也可以使用自定义网址打开应用.问题是当应用首次启动该方法时

In info.plist file I configured URL Identifier and URL Scheme successfully. Also I am able to open app using custom URL. The problem is when app launches first time the method

func scene(_ scene: UIScene, openURLContexts URLContexts: Set<UIOpenURLContext>) 

不打电话.

我有一些基于上述方法的依赖功能.因此，当应用程序首次启动时，我无法在应用程序中看到任何内容.

I have some dependent functionality based on above method. So when app launches first time I am not able to see anything in my app.

我也在方法中添加了代码

Also I added code in method

func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options connectionOptions: UIScene.ConnectionOptions) {
        
        guard let _ = (scene as? UIWindowScene) else { return }
        
        let url = connectionOptions.urlContexts.first?.url
        
    }

但是我在这里得到的网址为nil.

but I get url as nil here.

但是，如果我的应用程序处于后台模式并且我点击了URL，则上述方法调用成功并且相关功能正常运行.以下是我在sceneDelegate中scene(_:openURLContexts:)方法上的代码.

However if my app is in background mode and I hit URL then above method calls successfully and dependent functionality working fine. Following is my code on scene(_:openURLContexts:) method in sceneDelegate.

func scene(_ scene: UIScene, openURLContexts URLContexts: Set<UIOpenURLContext>){
        let url = URLContexts.first?.url
        let urlString: String = url!.absoluteString
        
        if let urlComponents = URLComponents(string: urlString),let queryItems = urlComponents.queryItems {
            queryParams = queryItems
        } else {
            print("invalid url")
        }
        
        guard let windowScene = (scene as? UIWindowScene) else { return }


        self.window = UIWindow(windowScene: windowScene)
        //self.window =  UIWindow(frame: UIScreen.main.bounds)

        let storyboard = UIStoryboard(name: "Main", bundle: nil)
        guard let rootVC = storyboard.instantiateViewController(identifier: "LocationViewIdentifier") as? UIViewController else {
            print("ViewController not found")
            return
        }
        let rootNC = UINavigationController(rootViewController: rootVC)
        self.window?.rootViewController = rootNC
        self.window?.makeKeyAndVisible()
    }

任何人都可以告诉我为什么上面的方法第一次不调用吗?

Can anyone tell me why first time above method does not call?

推荐答案

也许这会帮助您解决问题.

Maybe this will help your situation.

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

    let urlinfo = connectionOptions.urlContexts
    let url = urlinfo.first?.url as! NSURL

}

func scene(_ scene: UIScene, openURLContexts URLContexts: Set) {

    let url = URLContexts.first!.url as NSURL

}
