RootInstaller

public protocol RootInstaller

The object responsible to handle the installation of the first screen of the navigation.

The Navigator will call the RooInstaller.installRoot(identifier:context:completion:) method that will handle the setup of the screen to be shown.

   class AppDelegate: UIResponder, UIApplicationDelegate, RootInstaller {

     func application(_ application: UIApplication, didFinishLaunchingWithOptions ...) -> Bool {
       ...
       // setup the root of the navigation
       // this is done by invoking this method (and not in the init of the navigator)
       // because the navigator is instantiated by the Store.
       // this in turn will invoke the `installRootMethod` of the rootInstaller (self)
       navigator.start(using: self, in self.window, at: "screenA")
       return true
     }

     // install the root of the app
     // this method is called by the navigator when needed
     // you must call the `completion` callback when the navigation has been completed
     func installRoot(identifier: RouteElementIdentifier, context: Any?, completion: () -> ()) -> Bool {
       let vc = ScreenAViewController(store: self.store)
       self.window.rootViewController = vc
       completion()
       return true
     }
   }
  • Called by the Navigator when it’s time to install the root of the navigation.

         // install the root of the app
         // this method is called by the navigator when needed
         // you must call the `completion` callback when the navigation has been completed
         func installRoot(identifier: RouteElementIdentifier, context: Any?, completion: () -> ()) -> Bool {
           let vc = ScreenAViewController(store: self.store)
           self.window.rootViewController = vc
           completion()
           return true
         }
