I'm trying to set up an "IN" predicate like this:
NSArray* deletedAlertIDs = @[ @198, @197 ];
NSPredicate* pred =
[NSComparisonPredicate predicateWithLeftExpression: [NSExpression
expressionForKeyPath: @"keyShadow"]
rightExpression: [NSExpression expressionForAggregate:
deletedAlertIDs]
modifier: NSDirectPredicateModifier
type: NSInPredicateOperatorType
options: 0];
req.predicate = pred;
But it doesn't work, even though NSLog() shows it as "keyShadow IN {198, 197}",
which is the same as what I get when I use this code that works:
req.predicate = [NSPredicate predicateWithFormat: @"keyShadow IN %@",
deletedAlertIDs];
Clearly something is different between the two that's not shown in the
description.
