Ok it works, this is what I did:

CGContextBeginPath(ctx);
....
...   /.//create the outter 
...
CGContextClosePath(ctx);
...
... //Create the inner path

CGContextClosePath(ctx);
CGContextSetFillColorWithColor(ctx, CGColorCreateGenericRGB(0.5f, 0.5f, 0.5f, 
0.5f));
CGContextEOFillPath(ctx);

//Recreate the inner path to be stroke..
CGContextBeginPath(ctx);
..
.. //Inner path again
CGContextClosePath(ctx);
CGContextSetLineWidth(ctx, 3.0f);
CGContextSetStrokeColorWithColor(ctx, CGColorCreateGenericRGB(0.0f, 0.0f, 0.0f, 
0.5f));
CGContextStrokePath(ctx);

Ok the colors Im creating I have modified to create the colors then use them 
and then release them, otherwise I will have leaks. 

I will read again the Qartz PG, because I don't get the behavior of these paths

Thanks

Gustavo
