Moving cells from one table to another in iOS

I am trying to create an application with multiple table views that uses and implements Core Data. I would like the user to be able to select cells in one table and move them to another (like in Apple's mail application) using either a check accessory or a selectedCell method with an action sheet. I'm stuck because I don't know if you are actually moving the cell to another table or if you are adding a copy to the new table and deleting the original. Basically, I'm asking for a basic example of cell movement to give me a push in the right direction.

You would not be technically moving the cell to the other table. The way I would go about doing this would be to pass the NSManagedObjectContextID of the item between the tables, depending on how large your entities are and if the tables are in the same view controller.

You won't be moving cells. The model for a table view is an array. Move things between the arrays and tell the tables that their model has changed.

id somePartOfMyModel = [self.arrayA objectAtIndex:someIndexPath.row];
[self.arrayA removeObject:somePartOfMyModel];
[self.arrayB addObject:somePartOfMyModel];

// the simplest, non-animated way to update the tables.
// I'd advise getting this working first, then later trying fancier UI to indicate changes
[self.tableViewA reloadData];
[self.tableViewB reloadData];
