title: Add subview to a xib file
body: <p>I'm trying to add a label to a UIView in a xib file. When I run the app, the label doesn't shows up.</p>
  
  <pre><code>- (void)viewDidLoad {
      [super viewDidLoad];
      self.label = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 50, 200)];
      [self.label setText:@"This is a label"];
  
      xibView *myxibView = [[xibView alloc] init];
      [myxibView.myView addSubview:self.label];
  }
  </code></pre>
