i want to increase the values any where in the program and then want to update them in the class declared….

any idea how to achieve this???

Here’s a question (and good answers) about singletons.

You could also use the app delegate, as frankodwyer suggested, and access it from anywhere using:

id delegate = [[UIApplication sharedApplication] delegate];

For ease of use and type safety I use a category like this:

// 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 can access your app delegate from everywhere: [UIApplication sharedDelegate]
