In app purchase on cocos2d CCMenu button?

[joco]

Hi All,

Does anyone know a trick to get an in-app purchase button on a cocos2d CCMenu and have the whole purchase process stay on the CCMenu?

I have no association with this game but SuperRope (free game) has a setup where their store has several buttons for in-app purchase.

When you buy from them they do not pop up a UIView to complete the purchase.

I would like to achieve the same on a CCMenu with several CCMenu "buy" buttons.

Possible or do I have to use UIView with a xib and such?

Thanks
