Use delegate protocol.

In Home.h

@protocol RetailerDelegate <NSObject>

-(void) passDataToRetailer:(NSArray *)array;

@end

@interface Home:UIViewController
{
 Read readObj;
}
@property(assign, nonatomic) id <RetailerDelegate> delegate;

In Home.m

//call method where you want to pass data
[delegate passDataToRetailer:readObj.array];

In RetailerInfoViewController.h

@interface RetailerInfoViewController : UIViewController<RetailerDelegate>
{
 NSArray *localArray;
}

In RetailerInfoViewController.m

//in viewdidload
Home *parent = [self presentingViewController];
parent.delegate = self;

-(void) passDataToRetailer:(NSArray *)array
{
//here you receive your data
}

Hope this helps you...

if you want to acess the properties of another class first you need to import that .h file where you want and make object of that class. and access which method...

Suppose you need to acess the second view controller properties into FirstViewController.Then define SecondViewController.h file into FirstViewController.and make object

SecondViewController *controller = [[SecondViewController alloc]initWithNibName:@"SecondViewController" bundle:Nil];

controller.method;

// method what you want to access here...

Make the values or variables global . Declare the variables in Appdelegate and then import it where you want to. Also you can Make a singleton Class and import its values . It will be like passing values from one view to the other. As the variables will remain the same but the values will change according to your code.

Please have a look here :-
