Its not really a programming question but a design implementation question but anyway im wondering how you choose the text sizes in general according to the screen size. So an example is like before there was auto layout i used to say I want this views width to always be 30% of the superviews width. So no matter on what screen, be it iPhone or iPad, the width of the view will always be 30% of its superview. Now im wondering how would you choose the text size. Whats the rule of thumb for choosing the text size of a UILabel if its going to not look good on an iPhone but will look good on an iPad. What i would really want from everyone is for us to talk about rules of thumbs we use specifically when hitting my current situation. What do you do?
