PlayResultViewController *playResultViewController;

in classB.m

You are missing the initWithNibName to start with, here are some examples

With a Navigation controller u can use

BViewController *bController = [[BViewController alloc] initWithNibName:@"BViewController" bundle:nil];
[self.navigationController pushViewController:bController animated:YES];
[bController release];

without UInavigation controller you can test with

BViewController *bController = [[BViewController alloc] initWithNibName:@"BViewController" bundle:nil];
    self.view = bController; 
    // or alternatively self.view = bController.view;
    [bController release];

You need to tell it which nib to load....

playResultViewController = [[PlayResultViewController alloc] initWithNibName:@"Mynib" bundle:nil];
