Answer 1

- (void)drawRect:(CGRect)rect{      
    CGContextRef context= UIGraphicsGetCurrentContext();
    CGContextSetRGBStrokeColor(context, 0.0, 1.0, 0.0, 1.0);
    CGContextSetLineWidth(context, 1.0);
    CGContextMoveToPoint(context, 10, 50);
    CGContextAddLineToPoint(context, 100, 80);
    CGContextAddLineToPoint(context, 120, 120);
    CGContextAddLineToPoint(context, 60, 80);
    CGContextAddLineToPoint(context, 10, 50);
    CGContextSetFillColorWithColor(context, [UIColor redColor].CGColor);
    CGContextFillPath(context);
}

Answer 2

You can do this also with UIKit (ie higher level API):

UIBezierPath *path = [UIBezierPath ...];
...
[UIColor.redColor setFill];
[path fill];

This will fill your path i current graphics context.
