UIColor SetFill doesn't work

Question

In this code

for (int i=0;i<3;i++) {
    CGContextAddLineToPoint(context, self.xShift+15+self.rectLen*self.width+self.rectLen*(i+1), self.yShift+self.rectLen*         


        

Answer 1

setFill isn't for Core Graphics drawing but for drawing like [myUIBezierPath fill];

Instead set the fill color and stroke color using:

CGContextSetFillColorWithColor(context, [[UIColor cyanColor] CGColor]);
CGContextSetStrokeColorWithColor(context, [[UIColor blackColor] CGColor]);

Also, the following line:

CGContextDrawPath(context, kCGPathStroke);

Will only stroke the path, since the drawing mode is set to kCGPathStoke. To fill it as well you should replace it with

CGContextDrawPath(context, kCGPathFillStroke);

If your path has holes in it or crosses itself you should use even-odd fill and stroke

CGContextDrawPath(context, kCGPathEOFillStroke);
