title: Obj-C - if statement on array with images
body: <p>I've got an array which looks like this:</p>
  
  <pre><code>contentImages = @[@"img1.png", @"img2.png", @"img3.png"];
  </code></pre>
  
  <p>The images are displayed in a storyboard and the user can interact with them in a slideshow.</p>
  
  <p>But I want to check which image is currently shown and change a label to a custom text for that image only. So let's say image 1 will display "Lorem ipsum", whilst image 2 will display "Ipsum lorem" etc etc.</p>
  
  <p>Please help me!
  Thanks :)</p>
