Here's a question (and good answers) around singletons.. How do you duplicate a file in XCode? You could also use the app delegate, as frankodwyer suggested, and access it from anywhere using:. Unit testing an iPhone static library with XCode 3
id delegate = [[UIApplication sharedApplication] delegate]; 
For ease of use and type safety I use a category like this:. Image getting pixelated when used as part of an animation in iPhone animation
// put his in your delegate header file @interface UIApplication(MyAppAdditions) + (MyAppDelegate*)sharedDelegate; @end  // put his in your delegate implementation file @implementation UIApplication(MyAppAdditions) + (MyAppDelegate*)sharedDelegate {     return (MyAppDelegate*)[[self sharedApplication] delegate]; } @end 
Now you must access your app delegate from everywhere: [UIApplication sharedDelegate]. UITableView Animation Headache

You could make the integer and string properties of your app delegate and pass references to the delegate around to your views. I did any thing like this myself, though to be honest it is a pain and also a little error prone to make the app delegate available to all the views.. Or (and this is probably better), you could declare a singleton class (google the singleton pattern) as one of your data classes, and have your integer/string be properties of that. Then you could access the receive ters/setters of your singleton from anywhere in your program. You will need to take extra care if you have multiple threads however,.
