title: Is there Android Intent concept in iPhone SDK
body: <p>Just switching from Android to iPhone. In Android I can make several apps and use a tabView to call each app as intent.</p>
  
  <p>In iPhone, I can make several apps. I need a tab to call each apps or app views. Is there similar concept as intent in iPhone? Just switched to iPhone, copying all the other projects into the tabbar does not work out. If you have other methods to solve, I really appreciate. Thanks,</p>
