I am loading html into a UIWebView from iOS local file system. That HTML page is requesting json data on our server.

I can fetch the json data, so the question is, is there no cross domain policy in a UIWebView, or am I missing out something here?

It's the same as desktop Safari:

  • If you're loading a local (file) url in a UIWebView then there are no cross domain restrictions

  • If you're loading external urls they'll be limited to that domain, unless the site has correct Access-Control-Allow-Origin headers set.
