iOS, Universal links, Swift. continueUserActivity not calling

问题

I working on Universal links implementation for our iOS app.

Here is my small piece of AppDelegate:

private func application(_ application: UIApplication, openURL url: URL, sourceApplication: String?, annotation: AnyObject) -> Bool {
    DeepLinkHelpers.handleUniversalLink(url.absoluteString)
    return true
}

private func application(application: UIApplication, continueUserActivity userActivity: NSUserActivity, restorationHandler: ([AnyObject]?) -> Void) -> Bool {
    DeepLinkHelpers.handleUniversalLink(userActivity.webpageURL?.absoluteString)
    return true
}

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {

    signalRConnector.launch()

    NotificationCenter.default.addObserver(self, selector: #selector(AppDelegate.processRestartSignalRNotification(_:)), name: NSNotification.Name(rawValue: "restartSignalR"), object: nil)

    NotificationCenter.default.addObserver(self,                            selector: #selector(AppDelegate.reachabilityChanged(_:)),
                                           name: ReachabilityChangedNotification,
                                           object: reachability)

    do {
        try reachability.startNotifier()
    } catch {
        Logger.save(text: "Unable to start notifier")
    }
    return true
}

I have processed all other steps for universal links integration:

Published apple-app-site-association file in our Web application
Switched on Associated domains feature on developers.apple.com
Specified associated domains in xcode
Checked Target Membership for entitlements file
Said xcode to wait until app will be started manually (instead of autostart)

I doing following to debug:

Connecting ipad
Starting project in xcode
In ipad opening Calendar and click on link contained in some event. Link has following format: app.domain.com/#/123456789
Ipad opens app but continueUserActivity not calling and i can't handle code from the url for navigate to exact state within an app.

According documentation continueUserActivity should be executed. It is not executing both when app is running in background and when app not running.

Thank you in advance! Any help appreciated.

回答1:

I suspect this is because you've marked the continueUserActivity function as private. I've never seen that, and in fact Swift 3 actually gives an error when I try. There don't appear to be any examples of code structured that way on all of GitHub.

I'd suggest removing the private scope.

As of iOS 12, Swift 4.2, and Xcode 10 Apple has again changed method signature (type of restorationHandler) to

 func application(_ application: UIApplication, continue userActivity: 
NSUserActivity, restorationHandler: @escaping ([UIUserActivityRestoring]?) -> Void) -> Bool {

In 2019, this is what helped me (from this guide: https://medium.com/@abhimuralidharan/universal-links-in-ios-79c4ee038272 ):

func application(_ application: UIApplication, continue userActivity: NSUserActivity, restorationHandler: @escaping ([Any]?) -> Void) -> Bool {
    print("Continue User Activity called: ")
    if userActivity.activityType == NSUserActivityTypeBrowsingWeb {
        let url = userActivity.webpageURL!
        print(url.absoluteString)
        //handle url and open whatever page you want to open.
    }
    return true
}
