Go with following steps

  1. Declare the variables in delegate.h file

  2. write @property for the variable e.g.@property (nonatomic, retain) NSString *string;

  3. Synthesize in delegate.m

    @synthesize string;

  4. In the class(.h) where you want to use it

    //import yourDelegate.h YourDelegate *mainDelegate;

  5. In .m file

mainDelegate = [[UIApplication sharedApplication]delegate];

Before you push into your new view you can pass variables accross.

E.g.

ViewController * viewcontroller = [ViewController alloc] init;
//pass your variables in here by setting the variables in the view your pushing into
viewcontroller.calculation = self.calculation;
//push into new view 
[self.navigationController pushViewController:viewcontroller animated:YES]; 
[viewcontroller release];

this allows you to set the variable calculation in your new class by making it equal your calculation variable on your original view, before pushing to the new view.

When pushing a new view you can call methodes of that view. Don't know if that is what you are looking for.
