Does my *Entire* game have to be remade, to use Cocos2D?

I have been making my game in a pretty conventional manner. I just created a new window based application and have built off of that using my own images, table views, etc. Now I am about to begin programming the 开发者_StackOverflow中文版gameplay, and I just recently discovered Cocos2D. My question is this: In order to use Cocos2D for the actual gameplay (Which would take place in a single view) do I need to recreate my app from scratch? Or can I just make the one view using Cocos2D?

You could go down the mix-and-match route, but it would likely drive you insane.

If you want to embrace Cocos2D, you will likely be better off moving to it fully. More likely than not the time invested will be yield improvements in your existing code that you'll find surprising (certainly, I've found that rewriting something pretty much always yields a better solution in fewer lines of code).

You do not want to keep using the standard SDK in your game, if you're going to use Cocos2D for the game view (which you totally should).

Re-do the entire app in Cocos2D -- you'll have way more possibilities to make your game menus awesome and much less headaches; both while developing and while maintaining your game.
