You can do something like this. You can implement the below code in nextView.h

        NSString *fetchData;

also property and synthesize this 

       @property(nonatomic, retain)  NSString *fetchData;

implement this on button pressed code

         -(IBAction)save:(id)sender 
         { 
                nextview *admin = [[nextview alloc] init];

                admin.fetchData = name.text; 

                [self presentModalViewController:admin animated:YES];  
                [admin release];
          }

The viewDidLoad method is called before you had a chance to assign your NSString value. That's why you dont see the text in your UIButton. Try this :

-(IBAction)save:(id)sender 
{ 
    nextview *admin = [[nextview alloc] init];

    admin.fetchname = name.text; 

    [self presentModalViewController:admin animated:YES];  
    [admin release];
}

   -(IBAction)save:(id)sender 
   { 
          nextview *admin = [[nextview alloc]init];
          [self presentModalViewController:admin animated:YES]; 
          if (admin.view)
          { 
                 admin.fetchname = name.text; 
          } 
          [admin release];
   }

You release the instance of nextview right after you assign the name. That can't even work.

By the way, getname and fetchname are really bad chosen names for properties.
