I could not get any of this to work - maybe it is the rookie showing. Can you elaborate more or email me an example of the code you have working? OK, maybe I am missing something.

Well, I thought this would be easy, but I can't seen to get the row to actually select. Here's what I did so far: -Loop through for your items to find the index of the item with a serial number closest to the one you are searching for. Store this in a variable called index. -Select the row, using the following code: NSIndexPath* indexPath = [NSIndexPath indexPathForRow:index inSection:0]; [self.tableView selectRowAtIndexPath:indexPath animated:NO scrollPosition:UITableViewScrollPositionTop]; This scrolls to the correct row, but it doesn't seem to actually select it. The same code works perfectly if you do it in, for example, viewDidAppear, so I think that the problem is caused by doing it in -(void)searchBar:(UISearchBar*)searchBar textDidChange:(NSString*)text. I will have to do a bit more investigation to figure out why selection isn't working in this case. Hey there!

Can anyone show me how to use the search bar to select and scroll to the results? I have an array setup with Serial#. I would like to search for the serial number (i.e. 459) and it high light the closest serial number (i.e. 500), and scroll to that cell in the tableview. I am at a loss and just really getting into this - so all help will be appreciated greatly. This tutorial was nice, but I have a request.

This was my first iOS app that touched the network in any way, shape, or form. Aside from the incredibly annoying extra-long default timeouts, it went quite smoothly, and resulted in my open-source class ReallyRandom. [...] [...] The main new technology here was networking.

When the search bar text box length is 0, it sets isFiltered to False. Then it reloads the tableview. The code provided above is already handling that in the textdidchange.

I know I should use the [searchBar resignFirstResponder]; but where should I put it ? Another question is it possible to return the main list if the user deleted whats inside the search bar ??

I missed the part in the docs about block-based animation being the recommended method. I will have to switch over to them. I am still new to blocks, but they seem like pretty much the same thing as lambdas or anonymous methods in .NET, so they do make quite a bit of sense. #2 - Thanks for the code snippet; I plugged it into my demo project and it had exactly the effect I was looking for. And thanks for the demo project, it really helped to wrap my brain around the view hierarchy/alpha relationship! Having a visual tool to demonstrate it was a huge help. Cheers!
