I am newbie in iOS. I am creating SlideoutNavigation Menu using below Component of Xamarin. The Github link is below.
Link : https://github.com/thedillonb/MonoTouch.SlideoutNavigation
In this Component the whole thing is working fine. But I have a little Issue.
Initially my LoginViewController is looking like this.
Screenshot :
There is no Menu Button in the Left side.
Now When I login the New Open Screen with the Menu is look like this
Screenshot :
Now When open the SlideOut menu and select the Logout Option I want to start my LoginViewController it also working fine using below code.
Code :
var loginViewController = storyboard.InstantiateViewController("ViewController") as ViewController; BizApplication.clearCredential(); StyledStringElement logout = new StyledStringElement("Logout", () => NavigationController.PushViewController(loginViewController, true)){ TextColor = UIColor.White, BackgroundColor = UIColor.Clear }; logout.Image = new UIImage("filter_icon.png"); But Now I am getting below Screen which is not want. I want to remove that Left Menu icon in the Navigation.
Screenshot :
Any Help be Appreciated.
Update :
push code for new Controller open :
if (BizApplication.getCredential() != null) { window = new UIWindow(UIScreen.MainScreen.Bounds); Menu = new SlideoutNavigationController(); var webController2 = Storyboard.InstantiateViewController("SearchViewController") as SearchViewController; NavigationController.PushViewController(webController2, true); Menu.MainViewController = new MainNavigationController(webController2, Menu); Menu.MenuViewController = new MenuNavigationController(new DummyControllerLeft(), Menu) { NavigationBarHidden = true }; window.RootViewController = Menu; window.MakeKeyAndVisible(); loadingOverlay.Hide(); } My Flow :
I have use only one StoryBoard for my Project. So all the ViewController are in the same StoryBoard.
Deployment Info :
AppDelegate.cs I am not changing anything in this file.
SplashViewController.cs

If I do this in the DummyLeftControllers.cs then nothing is happen :
StyledStringElement logout = new StyledStringElement("Logout",() => CallthisMethod(storyboard)){ TextColor = UIColor.White, BackgroundColor = UIColor.Clear }; logout.Image = new UIImage("filter_icon.png"); void CallthisMethod(UIStoryboard storyboard) { var vwControllers = NavigationController.ViewControllers; foreach (UIViewController signiinVC in vwControllers) { if (signiinVC.GetType() == typeof(ViewController)) { this.NavigationController.PopToViewController(signiinVC, true); } } BizApplication.clearCredential(); NavigationController.PopToRootViewController(true); } 1 Answers

You are pushing SignInView controller on stack on Logout--which is incorrect. Write your code in a way that It use previously pushed view from stack..
In Splashviewconrtroller change following in viewdidload method:
base.ViewDidUnload (); storyboard = UIStoryboard.FromName ("Main", null); var webController = storyboard.InstantiateViewController ("ViewController") as ViewController; this.NavigationController.PushViewController (webController, false); if (Reachability.IsHostReachable ("http://google.com")) { if (BizApplication.CheckCredential ()) { //window = new UIWindow (UIScreen.MainScreen.Bounds); Menu = new SlideoutNavigationController (); storyboard = UIStoryboard.FromName ("Main", null); var webController = storyboard.InstantiateViewController ("SearchViewController") as SearchViewController; NavigationController.PushViewController (webController, false); Menu.MainViewController = new MainNavigationController (webController, Menu); Menu.MenuViewController = new MenuNavigationController (new DummyControllerLeft (), Menu) { NavigationBarHidden = true }; this.NavigationController.PushViewController (Menu); //window.RootViewController = Menu; //window.MakeKeyAndVisible (); } } On Logout..Call following:
void onLogOut (object sender, EventArgs e) { //Write your code to clear var vwControllers = this.NavigationController.ViewControllers; foreach(UIViewController signinVC in vwControllers) { if (signinVC.GetType () == typeof (ViewController)) { this.NavigationController.PopToViewController (ViewController); } } }
