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 UINavigationControllerDelegate 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.
Prior to iOS 7, the screen area covered by the NavigationBar and Toolbar was excluded from the area of the VisibleViewController. In iOS 7, the NavigationBar and Toolbar float over the child controllers' View. Application developers who wish to modify this behavior should manipulate the EdgesForExtendedLayout property.
The following illustration shows how layout of a UINavigationController is affected with EdgesForExtendedLayout. With the default value of All, the Frame of the UINavigationController's View includes the whole screen, extending beneath the toolbar at the bottom, the navigation bar, and even the status bar. The second image shows the Frame property when EdgesForExtendedLayout is set to None.
Layout can also be modified by setting the Translucent property of the NavigationBar to true.
