What is UIRectFill() in Monotouch?

Question

In a couple of ObjC projects in the overloaded drawRect: methods I have seen UIRectFill() being used. What is it doing and what is the equivalent of it in Monotouch?

For instance here, where is it putting the filled rectangle to/wher is it drawing it to:

CGRect borderRect = bounds;
UIRectFill(borderRect);
borderRect.origin.x = CGRectGetMaxX(bounds) - borderThickness;
UIRectFill(borderRect);

Answer 1

You're looking for UIKit.UIGraphics.RectFill.

Answer 2

You can use miguel de icaza's Rosetta Stone to find out the mappings between objective-c selectors and monotouch methods.

I also find the monotouch API documentation very useful although there is no direct mapping between functions and selectors.
