title: How to get all strings inside [...] in one NSString?
body: <p>Say given an NSString:</p>
  
  <pre><code>@"[myLabel]-10-[youImageView]"
  </code></pre>
  
  <p>I need an array of:</p>
  
  <pre><code>@[@"myLabel", @"yourImageView"]
  </code></pre>
  
  <p>How do I do it?</p>
  
  <p>I thought about going through the string and check each '[' and ']', get string inside them, but is there any other better way?</p>
  
  <p>Thanks</p>
