Following the example from the previous recipe, we will draw a circle and square on the screen.
Create a new Single View Application in Xamarin Studio and name it DrawShapeApp. Add a custom view to the project, like we did in the previous task, and name it DrawingView.
Perform the following steps:
Override the

In the
ViewDidLoadmethod of theDrawShapeAppViewControllerclass, initialize and display the view with the following code:DrawingView drawView = new DrawingView(new RectangleF(0f, 20f, this.View.Bounds.Width...
