title: How to call method from one class in another (iOS)
body: <p>This a very basic question but I've searched all over and been unable to find an answer that explains well enough for me to get my head around it.</p>
  
  <p>What I want to do is create a method in one class of my iOS app and then call that method from other classes in my app. Could someone explain exactly what I need to do to achieve this? Any help would be greatly appreciated as all my attempts so far have failed!</p>
  
  <p>Thanks.</p>
