Persisting data into multiple tables at the same time

[ashwinr87]

In my iPAD Application, I have 6 UITableViews and to load data for those views, I call 6 different webservices. Each Table view has its own database table/entity.

My operation for each of the tableview is that I would call a webservice using NSURLConnection and then parse the resulting XML using NSXMLParser and persist the data into the SQLite database using

[managedObjectContext save:&error];

command.

I would like to know if there is a way I would be able to persist data into multiple tables in SQLite at the same time.

If you are using Core Data, then you need to ignore the fact that it is using SQLite. Things will go a lot smoother that way.

thank you for the reply.. I am using core data.. what I meant to ask was that, is core data persistence possible for multiple entities at the same time?

There are techniques that you need to employ for multithreading. Google should turn up everything you need.

If you persist the data for one entity, as long as you are using the same entity across all table views, the data will modified. All you need is to call [table reloadData] on the Table Views you need updated.

Are all these views visible at the same time?
You could also use blocks, here is a blog post from Matt which I read yesterday, that might help.
