ios - 使用 Realm 过滤器对成员 '==' 的引用不明确

Question

 do {
        let result = try Realm().objects(Pros.self)
        print(result)
        let filterResult = result.filter({ $0.category.filter({$0.type_cat == ""})})

        print(filterResult)
    }
    catch {

        print(error)

    }

它给我的错误是“对成员‘==’的模糊引用”所以我想补充什么

Answer 1

我找到了解决方案，它对我来说非常有效

do {
            let result = try Realm().objects(Pros.self)
            print(result)
            let predicate = NSPredicate(format: "SELF.type == %@ AND SELF.status == 'valide' AND ANY category.type_sector = %@ AND SELF.status == 'valide'", arrType[(selectedFromType?.row)!], arrTypeSector[(selectedFromSector?.row)!])
            let arrFiltered =  result.filter(predicate)
            print(arrFiltered)


        }
        catch
        {
            print(error)

        }
