title: iOS5 - Storyboard - showing another view
body: <p>This is simple one though:
  I'm having XCode 4.2 with iOS beta7. I am just trying a to have to views with one button in first view. On click of button, it will show next view.
  In many tutorials, when I click and drag the button to next view, it will show "performSegueWithIdentifier:sender:" view.
  But in my interface builder, its showing "Storyboard Segues with Push, Modal, Popover, Custom......"
  I don't know whether I'm doing wrong or its the behavior of the xcode itself....
  can some one suggest me good tutorials for iOS5 storyboard please?</p>
