It seems we don't have an input box object yet in cocos2D. So I would like to implement a UIKit numeric input box in a popup (like it is in this game : http://groups.google.com/group/cocos2d-iphone-discuss/browse_thread/thread/c516a444d3e7c4c8/b88e6e72b36db6ae?lnk=gst&q=jps#b88e6e72b36db6ae)
Is there an example somewhere to perform such a thing ?
