How do I change the background color of a CGRect?

Also, how can I change it's alpa?

You don't. CGRect is a set of dimensions, not something visual.

Create a custom subclass of UIView.

Implement the drawRect method for the view.

Use the method UIRectFill to drill a rectangle. If you want the rectangle to be partly transparent you'll need to set the opaque flag on the view to NO and create a UIColor that's partly transparent.

Duncan, if all he wants to do is change the bg color and alpha then idt he needs to sublclass it and go to all the trouble. those are both properties of UIView so he can just make a UIView, give it a frame, and then alter the backgroundColor and alpha properties
