title: Why does [url pathComponents] contain an "/"?
body: <p>Take for example</p>
  
  <pre><code>NSURL *url = [NSURL URLWithString:@"eg://resources/users/1/answers/2"];
  NSLog(@"%@", [url pathComponents]);
  
  &gt;&gt; ( "/", "users", "a", "answers", "b" )
  </code></pre>
  
  <p>1) Why does the path contain a "/"? </p>
  
  <p>2) If what I want is the "users", is it safe to use the first index?</p>
  
  <pre><code>[[url pathComponents] objectAtIndex:1];
  </code></pre>
