What is the best way to remove warning?
===

I want to save data in core data. What is the best way to remove this warning?     

    @interface CDPage : NSManagedObject

    CDPage *corePage = [CDPage allocWithEntity:entity insertIntoManagedObjectContext:manageContext andWithBOPage:page];
    [[AppDelegate instance] saveContext];

warning: **Unused variable 'corePage'**
