How to achieve animation effects like(word puzzle game) in iphone application?

Question

i need to achieve an animation effect like (the Effects in "Pic Something","Pic Reveal" and so on) in my app.

What i am saying is i need to implement this tasks

Task1: when the user touches one Letter, then it change its frame(current position) to another frame(target position).

Task2:when the user touch the Letter(in Target position), it comes back to its original position again.

this can be clearly understood if u see the sample Apps.

I didn't find out any samples on internet also.

Thanks in Advance..

Take a look at UIView animation and animation blocks in iOS, that's what you need. With them you can create any animation you like. Here's a nice tutorial.

And about the whole system you described - I would create an NSDictionary of UIView positions and attach those to the corresponding tags of UIViews- this way you will always know from which place every UIView came from.
