Trying to implement JW Player on iOS
I found the problem: UIWebView doesn't have access to project files. So the jwplayer.js is not loaded. So either load the player to some web server, or replace
<script type="text/javascript" src="jwplayer.js"></script>
with
<script type="text/javascript">
Content of the file jwplayer.js (right click on jwplayer.js -> view source -> copy -> paste to here)
</script>
