I'm doing an NSMetadataQuery something like this:
NSPOT = NSLikePredicateOperatorType;
myPredicate = [NSComparisonPredicate
predicateWithLeftExpression:[NSExpressionexpressionForKeyPath:@"*"]
rightExpression:[NSExpressionexpressionForConstantValue:@"somestring"]
modifier:NSDirectPredicateModifier
type:NSPOT
options:options];
[myQuery setPredicate:myPredicate];
[myQuerystartQuery];
But I've not seen any examples of how to search for everything that DOESN'T contain "somestring".
I see some docs on NSCompoundPredicate and notPredicateWithSubpredicate, but does that apply to this style of predicate? If so, how would that work?
Chris
