A MonoTouch/Xamarin Forms implementation of MKNumberBadgeView allowing you to render badges on buttons other than TabBarButtons.
The BadgeView (UIView) can be used directly as a UIView in a MonoTouch project. To use the Xamarin Forms implementation the Badge (View) class can be used in Xaml or added programatically with the BadgeRenderer exported to delegate rendering into the BadgeView.
By default the BadgeView is drawn with the white border and gradient if the application is running an iOS version less than 7. Otherwise a pure red, borderless version will be rendered.
