Question

I am trying to draw a map annotation in my app – very much like MapKit’s MKAnnotationView, but without the mapkit.

I have a problem with the ordering of the path for the view outline that I cant figure out.

Code:

CGFloat minx = CGRectGetMinX(currentBounds);
CGFloat midx = CGRectGetMidX(currentBounds);
CGFloat maxx = CGRectGetMaxX(currentBounds);
CGFloat miny = CGRectGetMinY(currentBounds)+10.0f;
CGFloat midy = CGRectGetMidY(currentBounds)+10.0f;
CGFloat maxy = CGRectGetMaxY(currentBounds)+10.0f;

CGContextBeginPath(currentContext);
CGContextMoveToPoint(currentContext, minx, miny+radius); //before top left arc
CGContextAddArcToPoint(currentContext, minx, miny, midx, miny, radius); //top left

CGPoint points1[] = {
CGPointMake(midx-10.0f, miny),
CGPointMake(midx, 0.0f), //tip of arrow
CGPointMake(midx+10.0f, miny),
};
CGContextAddLines(currentContext,  points1, 3);
CGContextAddArcToPoint(currentContext, maxx, miny, maxx, midy, radius); //top right
CGContextAddArcToPoint(currentContext, maxx, maxy, midx, maxy, radius); //bottom right
CGContextAddArcToPoint(currentContext, minx, maxy, minx, midy, radius); //bottom left
CGContextClosePath(currentContext);

CGContextClosePath(currentContext);
CGContextDrawPath(currentContext, kCGPathFillStroke);
//CGContextDrawPath(currentContext, kCGPathEOFillStroke);

So the CGContextMoveToPoint was not working, no matter what values were entered, with or without the CGContextPathBegin. Starting the path with the line at the corner of the pointer arrow allowed me to specify starting point. Thanks Peter for helping me understand it, and how to simplify the paths.
