In iOS7, Apple introduced Dynamic Type system wide text size adjustment as per this article and this iOS programming guide.
This allows a user to configure larger or smaller fonts on their iOS device at a system-wide level for apps that support variable font sizing in order to improve accessibility.
Is there any way in titanium to listen for a UIContentSizeCategoryDidChangeNotification and then poll the preferredFontForTextStyle: on an iOS device within Titanium?
