Hi,

I am using the framework of route-me for working with locations. In this code the path between two markers(points) will be drawn as a line.

My Question: "What code should I add if I want to add an arrow in the middle(or top) of the line, so that it points the direction"

Thanks

- (void)drawInContext:(CGContextRef)theContext
{
    renderedScale = [contents metersPerPixel];

    float scale = 1.0f / [contents metersPerPixel];

    float scaledLineWidth = lineWidth;
    if(!scaleLineWidth) {
        scaledLineWidth *= renderedScale;
    }
    //NSLog(@"line width = %f, content scale = %f", scaledLineWidth, renderedScale);

    CGContextScaleCTM(theContext, scale, scale);

    CGContextBeginPath(theContext);
    CGContextAddPath(theContext, path);

    CGContextSetLineWidth(theContext, scaledLineWidth);
    CGContextSetStrokeColorWithColor(theContext, [lineColor CGColor]);
    CGContextSetFillColorWithColor(theContext, [fillColor CGColor]);

    // according to Apple's documentation, DrawPath closes the path if it's a filled style, so a call to ClosePath isn't necessary
    CGContextDrawPath(theContext, drawingMode);
}
