title: how to store WKInterfaceTimer value in a variable on button click in ios?
body: <p>I have designed my Watchkit app like that of a stopwatch.
  In the screen I have WKInterfaceTimer * timer, Start Button, Stop Button, Reset Button and a Lap Button.</p>
  
  <p>What I am trying to do is, when I press the "Lap" button the time that is displayed in the timer at the time of buttonPressAction should be stored in a variable.</p>
  
  <p>How do I do this in the interfaceController.m ??? NOT in swift..</p>
