From the documentation of UITableView / UITableViewController:

If you decide to use a UIViewController subclass rather than a subclass of UITableViewController to manage a table view, you should perform a couple of the tasks mentioned above to conform to the human-interface guidelines.

To clear any selection in the table view before it’s displayed, implement the viewWillAppear: method to clear the selected row (if any) by calling deselectRowAtIndexPath:animated:. After the table view has been displayed, you should flash the scroll view’s scroll indicators by sending a flashScrollIndicators message to the table view; you can do this in an override of the viewDidAppear: method of UIViewController.

So lets say I do my custom stuff here and I do not flash the scroll indicator, and I do not reset the selection (which I think is wrong anyways, the user wants to know from where he came from). Will they reject it?
