title: iOS Beginner: String concatenation
body: <p>I've concatenated string using the following code:</p>
  
  <pre><code>NSString *add = @"a ";
  lbl.text = [add stringByAppendingString:lbl.text];
  </code></pre>
  
  <p><em>Which adds 'a ' to lbl variable every time I call the function.</em> </p>
  
  <p>But for some reason this method concatenates in a way that the new string adds in the beginning of what's already there, and not to the end.</p>
  
  <p>Instead of getting AAABBB, I get BBBAAA. How do I fix this?</p>
