You’ve probably seen Paper by http://www.fiftythree.com/, the app is pretty cool and the drawings look really nice and smooth. I’m working on my personal app that needs something similar, and after doing some research I’ve seen that there isn’t really anything like that available, some people try to use catmull roms etc. but that doesn’t look good enough. I will show you how you can achieve pretty cool drawing app.

CocosBuilder is a free tool for graphically laying out sprites, layers and scenes for Cocos2D iPhone and Mac. It’s ideal for quickly and accurately creating menus and other parts of the interface, but can also be used to create levels, particle systems or any other kind of Cocos2D node graphs.

Tons of Cocos2D links

Here is my list of cocos2d open source games and programming resources for various purposes in cocos2d development. I hope it will help you to speed up learning and developing your games using this fantastic framework as it helped me making iUridium.

CCTMXTiledMap is useful, but it's absurdly slow for large maps, thus, HKTMXTiledMap is born. By pushing only polygons needed to the GPU, it drastically reduces render times by the GPU. Currently, it only supports orthogonal maps (no hex or isometric maps). Also added to it is animation functionality. This allows you to have data-driven animated tiles as done through the Tile Properties.
