Hi I have a table view, and when I delete a cell I am removing an item from an NSMutableArray, archiving that array, and removing the cell.

However, when I do this, it is causing the delete button to lag after I click it. Is there any way to fix this?

// Override to support editing the table view.
- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath {
    if (editingStyle == UITableViewCellEditingStyleDelete) {
        int row = [indexPath row]; 
        [savedGames removeObjectAtIndex:row]; 
        [tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationFade];

        //this line causing lag
        [NSKeyedArchiver archiveRootObject:savedGames toFile:[self dataFilePath]];
    }    

}

Thanks
