I need to draw an hexagon and fill it with a color build with an Image as pattern. I did:

CGContextSaveGState(context);
CGContextSetLineCap(context, kCGLineCapRo

    Try

    CGContextDrawPath(context, kCGPathFillStroke);
    

    Instead of

    CGContextStrokePath(context);
    CGContextFillPath(context);

    Either use

    CGContextDrawPath(context, kCGPathFillStroke);
    

    as sch suggested, or draw the hexagon again before calling FillPath. StrokePath and FillPath remove the path that you have added to the context, thus the next call will silently fail without a path.

    CGPathRef path = /* drawing hexagon here */;
    CGContextAddPath(context, path);
    CGContextStrokePath(context);
    CGContextAddPath(context, path);
    CGContextFillPath(context);
    

    Note: the two segments of code are not equivalent and gives different result.
