title: pushViewController animation not working for me
body: <p>I am doing view based app and i have added tableview. Now i have written in didSelectRowAtIndexPath method as below when user clicks on a row then navigate to "learncourse" nib.</p>
  
  <pre><code>if (indexPath.row == 1) {
      learncourse *learncourse1 =   [[learncourse alloc] initWithNibName:@"learncourse" bundle:nil];      
      [self.navigationController pushViewController:learncourse1 animated:YES];
      [learncourse1 release];
  }
  </code></pre>
  
  <p>But this is not working for me when click on the row.</p>
