title: Replace multiple spaces with a newline but leave single spaces
body: <p>I'm trying to manipulate an <code>NSString</code>. I want to neaten up the output. If there are multiple spaces in a row, they should be replaced with a newline.</p>
  
  <pre><code>NSString *myString = @"Name: Tom Smith           Old address       street name : 31 Fox Road      Dixton       0000";
  </code></pre>
  
  <p>My desired output from <code>NSLog()</code>:</p>
  
  <pre>
  Name: Tom Smith                  
  Old address     
  street name : 31 Fox Road                  
  Dixton         
  0000
  </pre>
  
  <p>Here's a bit of logic I have been working on. I'm not sure if it's correct.</p>
  
  <pre><code>    if (word_spacing &gt; 1)
          insert word in new line "\n"
      else
          carry on from the same line
  </code></pre>
