Open iOS app from URL AND Pass Parameters


Here is a nice tutorial on Using Custom URL Scheme in iOS

As in the tutorial, you should parse the URL parameters and store them to use in the app in this method:

- (BOOL)application:(UIApplication *)application handleOpenURL:(NSURL *)url {  // Do something with the url here}


On Xcode 12 this code works perfectly. You can imagine that this is also a URL as regular. In Source app you can call and open destination url with parameter like

    let url = URL(string: "DestinationApp:PATH?PARAMETER=11111")               UIApplication.shared.open(url!) { (result) in        if result {            print(result)           // The URL was delivered successfully!        }    }

Destination app can handle metod in AppDelegate with this method. Alert is for double check.

    func application(_ app: UIApplication, open url: URL, options: [UIApplication.OpenURLOptionsKey : Any] = [:]) -> Bool {            // Determine who sent the URL.            let sendingAppID = options[.sourceApplication]            print("source application = \(sendingAppID ?? "Unknown")")                // Process the URL.            guard let components = NSURLComponents(url: url, resolvingAgainstBaseURL: true),                let path = components.path,                let params = components.queryItems else {                    print("Invalid URL or path missing")                    return false            }                if let parameter = params.first(where: { $0.name == "PARAMETER" })?.value {                print("path = \(path)")                print("parameter = \(parameter)")                    let alert = UIAlertController(title: "Path = \(path)", message: "Parameter = \(parameter)", preferredStyle: .alert)                    let keyWindow = UIApplication.shared.windows.filter {$0.isKeyWindow}.first                    if var topController = keyWindow?.rootViewController {                    while let presentedViewController = topController.presentedViewController {                        topController = presentedViewController                    }                        topController.present(alert, animated: true, completion: nil)                }                return true            } else {                print("parameter is missing")                return false            }}
