title: Extending iOS KMLViewer Sample to Handle KML NetworkLink Elements
body: <p>I am developing an iOS app that displays KML data over an MKMapView.</p>
  
  <p>Apple's <a href="http://developer.apple.com/library/ios/#samplecode/KMLViewer/Introduction/Intro.html" rel="nofollow">KMLViewer</a> sample app has gotten me started.  Unfortunately, the KML data I am using relies heavily on linked files via the <code>NetworkLink</code>, <code>Link</code> and <code>href</code> KML elements, and KMLViewer's parser doesn't handle those.</p>
  
  <p>I can probably figure out how to add such support, but before I go down that road I was wondering if anyone else has already done this, or if there is a better starting point than KMLViewer.</p>
  
  <p>I've looked at <a href="https://github.com/mapbox/Simple-KML" rel="nofollow">Simple KML</a>, but it doesn't seem to support <code>NetworkLink</code> either.</p>
