Instagram like home feed

I need Instagram like home feed. App header should auto hide. Post header with username and timestamp should stick on top as long as next post's header replaces it. Refresh button should display initial array set from 0 to 10. When scrolling, array appends automatically, from 10 to 20, from 20 to 30 etc... Data given: NSDictionary {[ id:, username:, timestamp:, pic_http:, like count:, comment count:, description text: ] [ id:, username:, timestamp:, pic_http:, like count:, comment count:, description text: ] } [APP HEADER] + (REFRESH) ------------------------------- ---POST ONE--- -username -timestamp -picture -some info (likes, comments) -description, flexible text -action buttons ---/POST ONE--- ---POST TWO--- -username -timestamp -picture -some info (likes, comments) -description, flexible text -action buttons ---/POST TWO--- etc.. ARC on, but don't write stupid code, and please make it as beautiful as possible.
