Do what vinaykumar said, but you also want to open the FlyoutNavigationController from those UIViewControllers, so you have to pass that initial one you created to those controllers.
Otherwise if you just open your view controller, you won't be able to get the menu again.
I'm opening navigation controllers like so:
MainViewController in ViewDidLoad:
UIStoryboard board = UIStoryboard.FromName("MainStoryboard_iPhone", null);
UINavigationController nav = (UINavigationController)board.InstantiateViewController("nav");
SearchViewController searchVC = (SearchViewController)nav.ViewControllers[0];
// Passing flyoutnavigation here
searchVC.navigation = navigation;
SettingsViewController settingsVC = (SettingsViewController)board.InstantiateViewController("settings");
UINavigationController navSettings = new UINavigationController(settingsVC);
// Passing flyoutnavigation here
settingsVC.navigation = navigation;
navigation.ViewControllers = new[]
{
nav,
navSettings
};
In the other view controllers, (Settings and Search in my example), I have a public variable to store the FlyoutNavigationController (set in MainViewController) then add a button to open the FlyoutNavigationController that was passed:
// Set in MainViewController
public FlyoutNavigationController navigation;
public override void ViewDidLoad()
{
base.ViewDidLoad();
// Add button to allow opening the FlyoutNavigationController
NavigationItem.LeftBarButtonItem = new UIBarButtonItem(UIBarButtonSystemItem.Action, delegate
{
navigation.ToggleMenu();
});
}
