Is there something to tween the font size CCLabelTTF
in a nice way?
I guess using CCScaleTo
does not really recreate the font every iteration now does it?
There is no ("nice") way of tweening CCLabelTTF, as per the answer of LearnCocos2D.
So what I did, I just scale the rasterized version and on scale done I recreate it with font size scaled same, and also scale the node itself to 1 again.
