title: Reload the view in iphone (in viewWillAppear)
body: <p>I got a little app that has a button whose click is handled via</p>
  
  <pre><code>- (IBAction)click:(id)sender { }
  </code></pre>
  
  <p>Now, what I want is after click() runs, I want the view to refresh/reload itself, so that viewWillAppear() is re-called automatically.  Basically how the view originally appears.</p>
  
  <p>Of course I can call viewWillAppear manually, but was wondering if I can get the framework to do it for me?</p>
