I want a search field aka iTunes to filter my NSTableView. I have a list of
objects with a "title" field.
The filter predicate of NSArrayController sounds like something that might
help. I got as far as writing this predicate:
return [NSComparisonPredicate
predicateWithLeftExpression:[NSExpression expressionForKeyPath:@"title"]
rightExpression:<#(NSExpression *)rhs#>
modifier:NSDirectPredicateModifier
type:NSContainsPredicateOperatorType,
options:NSCaseInsensitivePredicateOption];
To filter on the title, but I'm stumped about what to put as the right side of
the predicate. It seems it should somehow refer to the NSSearchField, but I
don't know how.
I'm even more stumped about how to use the NSArrayController binding for filter
predicate.
Is it just me, or is a lot of this stuff undocumented, or at least very poorly
documented, or am I missing something? I'm always quite stumped figuring out
how to use a new binding.
