I am looking for a way to animate a view transition when using the following code to switch between views:

```
BuildCard2ViewController *aViewController = [[BuildCard2ViewController alloc] initWithNibName:@"BuildCard2" bundle:nil];

self.view = [aViewController view];

```

I don't have a navigation controller in the application to manage the cool transitions, looking for a way to fit into the above.

Thanks in advance!
