Adding a custom pop-up in Cocoa Touch

Im trying to add开发者_运维技巧 a custom pop-up, I dont want to use the Alertview class, I want to make a personalized pop-up, with only two buttons, ok and cancel, and to capture those events to use them later.

Im new to objective-c, what is the best approach to do this? (a working example would be better than nice)

Thx.-
