The following example shows how you can use this method in your code

notification = UIApplication.Notifications.ObserveContentSizeCategoryChanged ((sender, args) => {

Console.WriteLine ("WeakNewValue", args.WeakNewValue);
});
// To stop listening:
notification.Dispose ();
//
//Method style

NSObject notification;
void Callback (object sender, MonoTouch.UIKit.UIContentSizeCategoryChangedEventArgs args)
{
// Access strongly typed args
Console.WriteLine ("Notification: {0}", args.Notification);
Console.WriteLine ("WeakNewValue", args.WeakNewValue);
}
void Setup ()
