Calling an object declared in a function of one class from a function of another class

I am in a function of class A(tableview controller) where I have an object of class B(UserDetails class).Something like:

-(void) connectionFinishedLoading:(NSURLConnection*) connection :(UserDetails *) user{

//some code
user=A;
}

I want to use the value of "user" object in a function(different from the Class A function) of class C(table view controller).Something like:

 -(void)newfunction :(NSURLConnection*) connection{
 //I want to use the value of "user" here.
  }

Thanks.

Best possible way to store a value and use it in various classes is to use property of appDelegate class.

create a property in your appDelegate class say NSString *user; synthesize it

Create an instance of AppDelegate in connectionDidFinishLoading like 

YourAppDelegate *appDelegate = (YourAppDelegate *)[[UIApplication sharedApplication]delegate];
appDelegate.user = A;

Further in 

-(void)newfunction :(NSURLConnection*) connection{
 //I want to use the value of "user" here.
    YourAppDelegate *appDelegate = (YourAppDelegate *)[[UIApplication sharedApplication]delegate];
NSLog(@"%@",appDelegate.user);
  }

Store the object you need to use in different classes in a shared placeholder class like Singleton. Then simply get its shared instance and retrieve the object you need. Google a bit to get a pattern.
