You can declare the variable globally in AppDelegate & then can access in both viewController.
The changes made in the variable will reflect in both controllers.
Make the variable as a property of AppDelegate.h class
eg. @property (strong, nonatomic) NSString *Var;
& synthesize it in AppDelegate.m
@synthesize Var;
declare "AppDelegate * appDelegate" in both Controllers.h & then in controller.m in viewDidLoad write appDelegate=[[UIApplication sharedApplication]delegate];
now the variable can accessible using appDelegate.var anywhere in your code of both ViewController & changes are also reflected in both.
Hope this will work more efficiently for your need.
