i need simple iphone puzzle app:
user open the app and can see empty grid area(HomeView).
grid area: 5square x 5square
1 square : 64px x 64px
When user touch the some grid, move HomeView to PiecesView.
User choose the piece from PiecesView.
After decide the piece that user touch it, move to PiecesView to HomeView.
User can see the piece that user decided.
after that user can take a screenshot and tweet (if user want).
connect with twitter is a optional function.
so, it has a 2 TabView.
one is a HomeView and the other one is ProfileView that user login the twitter or not.
See the Puzzle
Select the Piece
See the User Profile (After Twitter login)
Login the Twitter or not
but it has several conditions　by some of the following.
1) I would like to using API, it's preferred that using NSXMLparser.
2) I don't like Interface Builder, please make it without IB (only code)
