Well then, how to start?
I've been using Gideros for a couple months and over that time have put together a solid library of graphics classes that I used on my last app.
The library has a TON of new functionality such as changing TextField font size AFTER creation, managed texture caching, loaded texture debugging, universal screen positioning, multi-line TextFields, anchorPoints on Containers (And Sub-classes!), global positioning and rotation, simplified coloring methods for Shapes, etc.
The amount of additions is pretty big, but do not worry! I have organized everything on a public BitBucket repository for all you fellow Giderosers!
Tool Page: http://www.giderosmobile.com/tools/display
(Example code doesn't show anywhere near the amount of API's the Display framework has)
Just be careful, the code probably has some hidden bugs due to how long it is (Over 1500 lines) so just submit an issue on BitBucket and I will try to fix it ASAP!! I do use this in a production app so it is pretty stable, but nonetheless, bugs always find a way to hide
Oh and lastly, here is my app you guys should totally check out https://itunes.apple.com/us/app/energy-collector-grid-wars/id684085556
Hope you guys find this library helpful!
