Q:

simple CATextLayer scaling problem

I'm having a simple scaling problem with CATextLayer, but i just couldn't figure it out:
I want the CATextLayer to proportionally grow in size with it's superlayer:
if the superlayer's width is 300 the text size of CATextLayer should be 12 and if the supeview's width is 600 the text size should be 24.
I couldn't find a working solution! 
Can you please give me a clue?
Thanks, Julian.

A:

You can scale the font size proportionately. For example, if the superlayer's width changes from 300 to 600, that's 600/300 = 2. Then multiply the font size by 2.
