    I'm dealing with the same problem right now. The UICatalog-sample from Apple seems to bring the dirty solution.

    It really doesn't make me happy at all. As mentioned before it uses [self.tableView deselectRowAtIndexPath:tableSelection animated:NO]; to deselect the currently selected row.

    - (void)viewWillAppear:(BOOL)animated
    {
        [super viewWillAppear:animated];
    
        // this UIViewController is about to re-appear, make sure we remove the current selection in our table view
        NSIndexPath *tableSelection = [self.tableView indexPathForSelectedRow];
        [self.tableView deselectRowAtIndexPath:tableSelection animated:NO];
    
        // some over view controller could have changed our nav bar tint color, so reset it here
        self.navigationController.navigationBar.tintColor = [UIColor darkGrayColor];
    }
    

    I have to mention the sample code may not be iOS 7 iOS 8 iOS 9 iOS 10-ready


    Something which really confuses me is the UITableViewController Class Reference:

    When the table view is about to appear the first time it’s loaded, the table-view controller reloads the table view’s data. It also clears its selection (with or without animation, depending on the request) every time the table view is displayed. The UITableViewController class implements this in the superclass method viewWillAppear:. You can disable this behavior by changing the value in the clearsSelectionOnViewWillAppear property.

    This is exactly the behavior I expect… but it does not seem to work. Neither for you nor for me. We really have to use the "dirty" solution and do it on our own.
