How to generate CGPath values ​​from logo

There is an interesting animation at the bottom of this page. It's basically animation CAShapeLayer

using UIPanGestureRecognizer

.

_{(source: ronnqvi.st )}

I wanted to see how it was done, so I went to the github page and found this one . Below is a small piece of code.

- (CGPathRef)loadPath
{
    CGMutablePathRef path = CGPathCreateMutable();
    // load
    CGPathMoveToPoint(path,     NULL, 7.50878897, 25.2871097);
    CGPathAddCurveToPoint(path, NULL, 7.50878897, 25.2871097,  21.7333976, 26.7812495, 29.6894527, 20.225586);
    CGPathAddCurveToPoint(path, NULL, 37.6455074, 13.6699219,  39.367189,  3.85742195, 31.9697262, 1.25976564);
    CGPathAddCurveToPoint(path, NULL, 24.5722639, -1.33789083, 21.99707,   10.9072268, 21.99707,   22.2255862);
    CGPathAddCurveToPoint(path, NULL, 21.9970685, 33.5439456,  15.9355469, 45.8212894, 8.99707031, 47.7294922);
    ...

      

        
        
        
      

    

How can I generate these values CGPath

? Any example would be helpful.
