申訴問題

Question

我在通過Safari通過鏈接打開應用程序時遇到問題（以后將來自我自己的應用程序）如果該應用程序已打開，則沒有問題。 如果應用未打開，則通過URL打開時會崩潰。 我已經學會了，那是因為我調用的appdelegate 2種不同的方法- didFinishLaunchingWithOptions和open url

打開應用程序時，通過打開的URL打開我沒有問題，但是如果我通過關閉的應用程序中的URL打開，則應用程序崩潰。 我了解到， didFinishLauchingWithOptions url參數可能為null，但是如何對其進行測試。 當我同時在模擬器和iPad上關閉應用程序時，XCode終止連接

編輯 -在Sachin Vas評論后，現在可以調試了。 在XCode調試中獲取此內容-但無法擴展有效負載

我的功能看起來像這樣

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
    self.window = UIWindow(frame: UIScreen.main.bounds)
    let storyBoard : UIStoryboard = UIStoryboard(name: "Main", bundle:nil)

    let nav = storyBoard.instantiateViewController(withIdentifier: "HomeNavController") as! UINavigationController
    let home = storyBoard.instantiateViewController(withIdentifier: "HomeViewController") as! HomeViewController



    if let url = launchOptions?[UIApplicationLaunchOptionsKey.url] as? NSURL {
        if let itemid = getQueryStringParameter(url: url.absoluteString!, param: "itemid"){
            NetworkService().getSpecificExercise(id: itemid) { response, error in
                let exercise = response! as VoiceExercise
                let vc = storyBoard.instantiateViewController(withIdentifier: "ExerciseViewController") as! ExerciseViewController
                vc.exercise = exercise
                switch exercise.type {
                case "STRENGTH":
                    vc.exercisetype = .strength
                case "RANGE":
                    vc.exercisetype = .range
                case "COMBINED":
                    vc.exercisetype = .combined
                default:
                    print(exercise.type)
                }
                nav.pushViewController(vc, animated: false)
                self.window?.rootViewController = nav
                //self.window?.makeKeyAndVisible()

            }
            return true
        }
    }else{
        //nav.pushViewController(home, animated: true)
        self.window?.rootViewController = home
        self.window?.makeKeyAndVisible()
    }

    nav.pushViewController(home, animated: true)
    self.window?.rootViewController = nav
    self.window?.makeKeyAndVisible()
    return true
}

func application(_ app: UIApplication, open url: URL, options: [UIApplicationOpenURLOptionsKey : Any] = [:]) -> Bool {
    if let itemid = getQueryStringParameter(url: url.absoluteString, param: "itemid"){
        NetworkService().getSpecificExercise(id: itemid) { response, error in
            let exercise = response! as VoiceExercise
            let vc = storyBoard.instantiateViewController(withIdentifier: "ExerciseViewController") as! ExerciseViewController
            vc.exercise = exercise
            switch exercise.type {
            case "STRENGTH":
                vc.exercisetype = .strength
            case "RANGE":
                vc.exercisetype = .range
            case "COMBINED":
                vc.exercisetype = .combined
            default:
                print(exercise.type)
            }
            self.window?.rootViewController = vc
            self.window?.makeKeyAndVisible()

        }
        return true
    }else{
        return false
    }

}

您可以檢查url的主機不為null，以及是否讓url如下所示

if url.host == nil
{
  return true;
}

if let sUrl = url
 {
   urlString = url.absoluteString
 }

希望能幫助到你！

更新

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
    if let launchOptions = launchOptions {
        if #available(iOS 9.0, *) {
            if let url = launchOptions[UIApplicationLaunchOptionsKey.url] as? UIApplicationShortcutItem {
                print("url: \(url)")
            }
        }
    }
    return true
}
