This isn’t a native iPad app. This is a HTML5 web app which runs from the iPad’s local storage (so it will display offline).
What I need to do is have a form which collects information and stores it somewhere locally for retrieval later.
Is there any way I can achieve this. I don’t care how the data is stored, just that it doesn’t expire (like cookies do) and its relatively easy to retrieve at a later date.
Thanks
Apple have a Safari Client-Side Storage and Offline Applications Programming Guide section in their documentation. It lists the various options.
Key-Value storage sounds like it best fits your usecase.
