title: How can I join path fragments using objective-C in iOS?
body: <p>What's the objective-C equivalent of python's <code>os.path.join</code> in iOS? e.g.:</p>
  
  <pre><code>&gt;&gt;&gt; import os
  &gt;&gt;&gt; os.path.join("foo", "bar", "buuxometer", "hi.jpg")
  'foo/bar/buuxometer/hi.jpg'
  </code></pre>
