Idea for adding values to screen dynamically.

I haven't used them yet, but from my understanding of them, Collection Views will cure what ails you:

Edit: I just realized why the code examples in the above look so odd... it's because they're using C#/MonoTouch.

Here's a guide with some examples using Obj-C/Cocoa Touch:

You will need to break down your question in several parts ^_-
So you actually got all working, expect the showing data?
What kind of data do you want? You want a Gridview Controller? (I tend to use Grids alot, because I can modify them the way I want..), these are not standard, but there are GREAT components out there, easy to implement.
