title: popup dialog- iOS
body: <p>What is the best way to implement a popup dialogue for iOS? </p>
  
  <p>I need a UIView that allows the user to select smileys, and a button to dismiss the UIView</p>
  
  <p>I do not know enough about Apple's interface guidelines to make the decision. Are there any apple classes that I should use, or 3rd party open source projects? </p>
