NSPredicate ( nsdictionary+array+nsdictionary)

Question

我尝试过NSPredicate，但是一直都得到响应0。检查吹风代码，并提供您的建议哪里出错。灵魂阵列：-{

CityId = 0;
TreatmentProgramServices =     (
            {
        TreatmentServicesId = 9;
        TreatmentServicesName = Coed;
    },
            {
        TreatmentServicesId = 1;
        TreatmentServicesName = Intervention;
    },
            {
        TreatmentServicesId = 3;
        TreatmentServicesName = Residential;
    }
);
TreatmentProgrameId = 3;

}

filterTreatmentServices是数组计数是:- {3}

 NSPredicate* updatePre =  [NSPredicate predicateWithFormat:@"(%K IN %@)",@"TreatmentProgramServices.TreatmentServicesId" ,filterTreatmentServices];

 filterTreatmentService =[soureceArray filteredArrayUsingPredicate:updatePre];

请提出解决办法

Answer 1

请用这个

  NSArray *filterArray=[soureceArray filteredArrayUsingPredicate:[NSPredicate predicateWithBlock:^BOOL(id  _Nonnull evaluatedObject, NSDictionary<NSString *,id> * _Nullable bindings) {
                return [[evaluatedObject valueForKey:TreatmentServicesId]  == 3];
            }]];
