If you’ve enabled multiselection you should be able to use UITableView’s indexPathsForSelectedRows to get all the indices of the selected rows. With this you can refer back to your original data downloaded from the server and get the strings you need.

You can use it within tableView:didSelectRowAtIndexPath: to build a string of all the currently selected rows.

EDIT:
To store a few pieces of associated data together you can use an NSDictionary (or NSMutableDictionary if you need to edit it after creation).
For example for your code, to store all the data for one row:

NSMutableDictionary * dict = [[NSMutableDictionary alloc] initWithCapacity:3];
[dict setObject:[media1 objectAtIndex:indexPath.row] forKey:@"image"];
[dict setObject:[story objectAtIndex:indexPath.row] forKey:@"story"];
[dict setObject:[descriptiondesc objectAtIndex:indexPath.row] forKey:@"desc"];

or you could create it straight into a regular NSDictionary, see here: http://developer.apple.com/library/mac/#documentation/Cocoa/Reference/Foundation/Classes/nsdictionary_Class/Reference/Reference.html
