I think you need to split the question for two. There is no any relation between them

I think I do not need to use sqlite. How can I keep the value in a multi dimension arrays?
If you just need it for the life of the application (not after exit/relaunch), just use an app delegate variable. Otherwise, create a core data entity and persist/retrieve the objects as necessary. Here's a tutorial:
http://developer.apple.com/iphone/library/documentation/DataManagement/Conceptual/iPhoneCoreData01/Introduction/Introduction.html
Multi dimension arrays can be solved with related entities. For example, a widget group has widgets, and each widget has components. You'd model a WidgetGroup, a Widget, and a WidgetComponent entity, and model the relationships accordingly (setting the multiplicity to one-to-many, or even many-to-many).

Dear Sir
I read http://developer.apple.com/iphone/library/documentation/Cocoa/Reference/Foundation/Classes/NSUserDefaults_Class/Reference/Reference.html
but still not understand how to assign a UIButton value to a delegate variable.
I do not need core data entity.
I just want to create a global variable and can get it across ViewController.m
Do you know any online tutorial in youtube or somewhere else?
