How to print out a CGPathRef for debugging purposes

gistfile1.txt

static void outputApplier(void* info, const CGPathElement* element)
{
	NSMutableArray* a = (NSMutableArray*) info;
    
	int nPoints;
        NSString * pathElementType = nil;
    
	switch (element->type)
	{
		case kCGPathElementMoveToPoint:
			nPoints = 1;
                        pathElementType = @"kCGPathElementMoveToPoint";
			break;
		case kCGPathElementAddLineToPoint:
			nPoints = 1;
                        pathElementType = @"kCGPathElementAddLineToPoint";
			break;
		case kCGPathElementAddQuadCurveToPoint:
			nPoints = 2;
                        pathElementType = @"kCGPathElementAddQuadCurveToPoint";
			break;
		case kCGPathElementAddCurveToPoint:
			nPoints = 3;
                        pathElementType = @"kCGPathElementAddCurveToPoint";
			break;
		case kCGPathElementCloseSubpath:
			nPoints = 0;
                        pathElementType = @"kCGPathElementCloseSubpath";
			break;
		default:
                        nPoints = 0;
                        pathElementType = @"unknown path element type";
			return;
	}
    
    NSMutableString * pointsList = [NSMutableString new];
    for (int i = 0; i < nPoints; i++)
    {
        [pointsList appendFormat:@" (%@)", NSStringFromCGPoint(element->points[i])];
    }
    
    NSLog(@"%@ : %@", pathElementType, pointsList);
}

CGPathRef somePath = ...;
CGPathApply(somePath, NULL, outputApplier);

Thanks. BTW you may find it useful, console command does similar out of the box p (void)CGPathPrint(pathRef, 0). Found in NSHipster Blog.
