Help Please!! Sending text to a new view

I have a simple table that drills down to a detailed view. I want to have an info button display more info relating to the detail view. I have everything working except the more detailed text. Here is how my project is setup

RootViewController

Drill down to ViewController

then the ViewController displays the more detailed view.

I'm using

- (void)viewWillAppearBOOL)animated {

code to display the new view.

}
on the ViewController

Do I need to setup a NSString to pass the data or something else. Please Help!!!

I hope someone can understand this. Thanks
