  <p>I'm new to objective c and I would like to add the following functionality to my app:</p>
  
  <p>I have a label which has default text after the app launches.
  I want for that label to change to a random string each time the user clicks a button.
  It does not matter if the string repeats itself eventually, as long as it is random.</p>
  
  <p>I appreciate the help in advance.</p>
