I am new at iPhone development and am trying to make an iPhone native app using c-objective in Xcode . i want to make an app that just displays an analog clock along with a calendar and weather on a single screen and are swapable with one another , that is the user can move the particular object in place of another object . please guide me which frameworks can i use to achieve this task . i read online about cocos2d which is for game development so am not sure if i should use that for now or not. i am right now trying to make this work in xcode 4.0 using windows based application ..
