How to create Multi-Level Game with Cocos2D(iOS)?

Question

1. I want to know how to create multi-level games with cocos2d.
2. I knew that big developers like Angry Birds, Cut the Rope have their own level-editor, but how does other people create multi-level games?

Question: How I can create/build levels, is there any kinds of builders? Or you need to create class for each level?

Answer 1

I am using single Scene/Layer and dynamically loading level data from XML (map images, collision, enemy formation definition, ...). It depends on your requirements. Are your maps endless?

Answer 2

I'm currently using Levelhelper for an upcoming game.. It really helps and heavily reduces the development time. Instead of writing your own parser, and trail-and-error xml files, you get a nice editor with lots of features. I would recommend it, definitely if you haven't endless levels.
