Demo which can share photo and text to Facebook/Twitter

***PLEASE READ CAREFULLY, AND ENSURE THAT YOU CAN DO IT BEFORE BIDDING. DON'T WASTE OUR TIME** I have an iPhone app, to which i want to add Facebook/twitter integration. I want to share a photo to Facebook or twitter in the new version of my iPhone app. Hope someone who has such experience can give me a demo source codes, which can share a photo with Facebook and twitter. Mockup has been attached. Note that Weibo (Chinese twitter) is not the MUST, but it is a bonus. As the mockups attached, i need: 1. Login: type username/password 2. textbox + thumbnail + word counter: user can type some text, and post the text and the image 4. There should be a thumbnail and text posted on faceboox/twitter. ** Note that sharekit do not fully match my requirement for the moment** That's all Thanks!
