Sharing using vkontakte, odnoklassniki, kaixinrepaste

I am developing an iphone application in which i need to share images to to the below social networks. 1) vkontakte, 2) odnoklassniki, 3) kaixinrepaste

I dont get any ideas where to start. Do anyone have some ideas? O开发者_C百科r Is there anything available like Sharekit for these social networks?
