Remarks

The Xamarin API supports two styles of event notification: the Objective-C style that uses a delegate class or the C# style using event notifications.

The C# style allows the user to add or remove event handlers at runtime by assigning to the events of properties of this class. Event handlers can be anyone of a method, an anonymous methods or a lambda expression. Using the C# style events or properties will override any manual settings to the Objective-C Delegate or WeakDelegate settings.

The Objective-C style requires the user to create a new class derived from UINavigationBarDelegate class and assign it to the P:UIKit.Delegate property. Alternatively, for low-level control, by creating a class derived from NSObject which has every entry point properly decorated with an [Export] attribute. The instance of this object can then be assigned to the WeakDelegate property.

Structure

The UINavigationBar maintains a stack of UINavigationItems. The UINavigationBar displays the TopItem UINavigationItem. You can push and pop UINavigationItems using PushNavigationItem(UINavigationItem, Boolean) and PopNavigationItem(Boolean).

The UINavigationBar is most commonly seen in conjunction with a UINavigationController, which manages the UINavigationBar and pushes and pops the necessary UINavigationItems.

Each UINavigationItem defines left, center, and right subviews. The left and right subviews are expected to be of type UIBarButtonItem, while the center subview by default displays the value of the Title property. The center view can be further customized by assigning to the TitleView property.

When used with a UINavigationController, the current UIViewController's NavigationItem property is used to manipulate the UINavigationBar, as shown in the following example.

public class MyViewController : UIViewController
{
   public override void ViewDidLoad ()
   {
      base.ViewDidLoad ();

      this.NavigationItem.Title = "NavigationItem.Title";
      this.NavigationItem.RightBarButtonItem = new UIBarButtonItem(UIBarButtonSystemItem.Action, OnAction);
      //...etc....

Application developers who wish to customize the behavior of the UINavigationController's uniquely-styled '"Back" button when using a UINavigationController can use the following technique:

public class MyViewController : UIViewController
{
   public override void ViewWillDisappear(bool animated)
   {
      base.ViewWillDisappear(animated);
      //If `this` not in stack, we've been popped via "Back" button
      if(NavigationController.ViewControllers.Contains(this) == false)
      {
         Console.WriteLine("Custom behavior");
      }
   }
}
