SKNode scale from the touched point

Question

I have added UIPinchGestureRecognizer to my scene.view to scale my content. I actually scale the parent node where all my visible contents reside. But I have problem though

Answer 1

Can't zoom I don't know why but the main problem is those SKT_INLINE. I've googled them and didn't found anything about 'em... The problem is when I copy/paste them in my project the compiler tells me I have to add an ";" right after them. I wonder if that's the reason that I can zoom.
