1- is it possible to use interface builder to design the game background and then use code to add cocos2d objects?
2- Is it possible to use iphone UI objects as well as cocos2d objects, for example uibutton, uiScrollView, etc.
3- is it possible to useiphone default template, and cocos2d templates togather? for example my home screen is a simple viewcontroller which is loading from a xib file, but the actual game page is a cocos2d template, which has no xib file, and the navigate between them?
