different view controllers

[iphoneSDKid]

How do you set a property in one view controller and then retrieve that value in a different view controller? Like in a game when you choose the level in one view, and then actually play the game in a different view?

and by the way how do you test what a string is for example do i use:

if (myString.text == @"text") {

or

if (myString.text == [NSString stringWithFormat:@"text"]) {

or neither?

You should get something like "Learn Objective-C on the Mac" from the same publisher as your iPhone SDK book. I don't have the book but if you go to the Apress site and look for it, they have a Google Preview link for the book. In the preview on pages 136 to 137 it discusses string comparison.
