Я перепробовал так много подходов и безуспешно искал в Интернете.Вот самый простой подход, который я пробовал и не могу заставить его работать:
Если я запускаю этот код, он правильно отображает панель вкладок, но когда я нажимаю на вкладки, я получаю исключение, которое я вставил в следующем примере кода.
Это метод из моего MainMenu.cs, который является записью xib.
Я ценю любую помощь в этом.Заранее большое спасибо!
private void Render_Screen (object sender, RenderScreenEventArgs e)
{
UITabBarController tabbarController = new UITabBarController();
UINavigationController navController1 = new UINavigationController();
UINavigationController navController2 = new UINavigationController();
UIViewController a = new UIViewController();
a.TabBarItem = new UITabBarItem(UITabBarSystemItem.Contacts, 0);
UIViewController b = new UIViewController();
b.TabBarItem = new UITabBarItem(UITabBarSystemItem.Favorites, 1);
UIViewController[] arrayA = new UIViewController[] { a };
UIViewController[] arrayB = new UIViewController[] { b };
navController1.ViewControllers = arrayA;
navController2.ViewControllers = arrayB;
UINavigationController[] arrayC = new UINavigationController[] { navController1, navController2 };
tabbarController.ViewControllers = arrayC;
InvokeOnMainThread (delegate {
this.View.AddSubview (tabbarController.View);
});
}
