Access localStorage in iOS apps

I'm serving up remote html/javascript content into an iPad app. Javascript code runs great and html renders fine, but any attempt to access localStorage throws "Security_err: dom exception 18".

I was attempting to use localStorage because Safari by default won't accept third party cookies. Is there any way to set cookies or store values in localStorage from开发者_开发百科 remote content to maintain state when served into an iOS app?

I know this question is old (and gaining dust), but here's an answer.

exception 18 is usually a cross domain permission issue.

consider one of the following solutions:

1. Instead of preloading the html string and then using [myWebView loadHTMLString:str baseURL:url];, just let the webview handle the whole request life cycle using [myWebView loadRequest:someNSURLRequest];

2. If your'e using Cordova, Edit your Cordova.plist file, add a new entry to the ExternalHosts list with the value * (please consider the security compromise with this solution).
