title: How to Push an UIViewController with NIB file
body: <p>I'm new to iOS development and I'm having a big headache not understanding something that may be pretty easy. 
  Basically I'm using a UITableViewController to go to another UITableViewController, but then I need to go from that second UITableViewController to a UIViewController. I want this UIViewController to have a .xib file for me to make a quick UI but I can't seem to find the way to push from the Second UITableViewController to this UIViewController. 
  I managed to programatically show a label, but not a UI from a .xib.</p>
  
  <p>This is the code that works with the programmatic label:</p>
  
  <pre><code>- (void)tableView:(UITableView *)tableView
  accessoryButtonTappedForRowWithIndexPath:(NSIndexPath *)indexPath
  {
      self.detailController.title = @"Disclosure Button Pressed";
      NSString *selectedMovie = self.movies[indexPath.row];
      NSString *detailMessage = [[NSString alloc]
                                  initWithFormat:@"This is details for %@.",
                                  selectedMovie];
      self.detailController.message = detailMessage;
      self.detailController.title = selectedMovie;
      [self.navigationController pushViewController:self.detailController
                                          animated:YES];
  }
  </code></pre>
  
  <p>And this is the .m of the UIViewController that works to show a UILabel programatically.</p>
  
  <pre><code>@implementation BIDDisclosureDetailViewController
  - (UILabel *)label;
  {
      return (id)self.view;
  }
  - (void)loadView;
  {
      UILabel *label = [[UILabel alloc] init];
      label.numberOfLines = 0;
      label.textAlignment = NSTextAlignmentCenter;
      self.view = label;
  }
  - (void)viewWillAppear:(BOOL)animated;
  {
      [super viewWillAppear:animated];
      self.label.text = self.message;
  }
  @end
  </code></pre>
  
  <p>Basically I don't want to create any UIObject Programatically, I need a .xib to create the UI.</p>
  
  <p>Thanks</p>
