tableView reloadData and deselectRowAtIndexPath

Question

I am using the following code to deselect a selected table view cell when returning back to the table view in -viewWillAppear:animated.

[self.tableView deselectRowAtIndexPath:self.tableView.indexPathForSelectedRow animated:YES];

I also need to reload the table view's data in this case but when you do that it clears the selected state of the selected cell so you don't see any fade animation.

Is there a way to reload the table data and also preserve the selected state to create the deselect animation?

Answer 1

After several attempts, I've found something that works. You need to set the deselection to occur after a "delay" (of 0 seconds) in order to make sure it happens on the next draw cycle and gets animated properly.

- (void)viewWillAppear:(BOOL)animated
{
    [super viewWillAppear:animated];

    NSIndexPath *indexPath = self.tableView.indexPathForSelectedRow;
    [self.tableView reloadData];
    [self.tableView selectRowAtIndexPath:indexPath animated:NO scrollPosition:UITableViewScrollPositionNone];

    [self performSelector:@selector(deselectRow) withObject:nil afterDelay:0];

}

- (void)deselectRow
{
    [self.tableView deselectRowAtIndexPath:self.tableView.indexPathForSelectedRow animated:YES];
}

Try this in your viewDidLoad:

    [self setClearsSelectionOnViewWillAppear:NO];
