Question

I have a native application that uses a UIWebView and notice that with sites like Google, they are using an HTML5 local database for storing information. I am using native APIs for clearing items out of the cookie store, but clearing the persistent cookie store does nothing to remove these local databases. Is there a way to remove them through a native API?

UPDATE:

Is there a way to do this through a non-native API or javascript?

Answer 1

You can run this JavaScript directly in your url bar:

javascript:localStorage.clear();

Note that local storage is same domain scoped, so it will clear the storage
of the current domain that you are.

Currently google uses it for google Analytics, adSense, etc.
