title: Create a for loop to add 39 buttons to an array
body: <p>I have 39 different UIButton variables in my .h file, but I would like to add each of them to an array without having to type out the same thing 39 times.</p>
  
  <p>Is there a way that I could do this in a for loop?</p>
  
  <p>The buttons are named accordingly: btn1,btn2,btn3 etc.</p>
