title: IBAction Events meaning
body: <p>I've been trying to get my head around Swift and building a simple iOS app.
  I've checked online, but I'm not entirely sure what to search anyway, I was just wondering does anyone know a website or can just straight up tell me what all of the IBAction Events mean.</p>
  
  <p>Touch Up Inside means when the button is clicked and released, although I'm not sure why.
  There is touch up outside, Editing changed, editing did begin, and another 10 or so.</p>
  
  <p>I would really appreciate it.</p>
  
  <p>Thank you  </p>
