Wow, I can't believe I missed this. Apple's sample code says:
- (void)search:(id)sender {
[self rearrangeObjects];
}
Just change that to:
- (void)search:(id)sender {
searchString = [sender stringValue];
[self rearrangeObjects];
}
and sorting works without the binding. Sorry for not remembering that
bit earlier.

Thanks for the reply Justin. Sure enough the sorting problem is
working, but removing the value binding on the search string did not.
When I do a check on its value in the search method it is always null.
I am assuming that the likely cause of this is that the searchString
is no longer accessible.
I attempted to make an outlet for the search field, but that had no
effect. I am going to keep playing with it, but if anyone has any
other suggestions I would appreciate it.

Well the reason you don't get sorting with an empty searchString is
because you return the array "as is" in the first 2 lines of the
method. I had to deal with both of the problems you're having a
couple days ago. Sorting takes place in [super
arrangeObjects:filteredObjects], so you'll want to always call that
at the end of your subclass. Better code would be:
- (NSArray *)arrangeObjects:(NSArray *)objects {
if (searchString == nil) {
return [super arrangeObjects:objects];
}
//snip... lala...
}
And the NSSearchField loses focus because of the way the example has
you set it up in IB. They make you connect it's search action but
also bind it's value to searchString in your array controller. What
ends up happening is:
NSSearchField calls the -search: action after timeout.
Array controller sets searchString from NSSearchField.
Binding causes NSSearchField to update itself with the "new" value
in searchString.
Updating NSSearchField's value causes you to lose focus.
So get rid of the value binding on NSSearchField and you'll keep
focus. I *think* that's all I had to do. If not, I'll pull out my old
project.
