title: Present a UIView over a view
body: <p>How can I make a custom view in iOS which appears above the existing view,but smaller? It should be like UIAlertView, but taken from a .xib file. After user taps a certain button, the small view vanishes and the normal view appears.</p>
  
  <p>If this is posiible, how can I do it? And.. if it's not hard for you, please, include code.</p>
  
  <p>Thanks in advance!</p>
