UITableViewCell doesn't get deselected when swiping back quickly

Question

I've now updated three of my apps to iOS 7, but in all three, despite them not sharing any code, I have the problem where if the user swipes to go back in the navigation controller (rather than tap the back button) quickly, the cell will remain in its selected state.

For the three apps, one uses custom cells created programmatically, another uses custom cells created in a storyboard and the third uses default cells in a very basic subclass of UITableView, also in a storyboard. In all three cases, the cells don't deselect by themselves. If the user swipes slowly, or hits the back button, they deselect as normal.

This is only happening in my iOS 7 apps, Apple's own apps and third party apps upgraded for iOS 7 all seem to be behaving normally (albeit with slight differences in how quickly the cells gets deselected).

There must be something I'm doing wrong, but I'm not sure what?

Answer 1

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.
