title: How to connect two view controllers to one button in storyboard?
body: <p>Up to now, there is a button in a view controller (let's call it Main View Controller). What I want is: if it satisfies a certain condition, when I press the button, the segue would lead to View Controller A; if not, when I press the button, it would lead to View Controller B.
  But it seems that one button can only have one segue from it, so I wonder whether what I want is possible to be achieved in storyboard???
  Thanks in advance!!!</p>
