ios - NSPredicate with ANY and "=nil" doesn't work -


this condition works

nspredicate *predicate = [nspredicate predicatewithformat:        @"any region.beacons.major = %d",rangedbeacon.major.intvalue];

but not

nspredicate *predicate = [nspredicate predicatewithformat:        @"any region.beacons.minor = nil"];

beacons list inside region object. major , minor have type nsnumber

you may try this:

nspredicate *predicate = [nspredicate predicatewithformat:@"any region.beacons.minor = $minor"]; predicate = [predicate predicatewithsubstitutionvariables: [nsdictionary  dictionarywithobject:[nsnull null] forkey: @"minor"]];
