我有其他领域对象列表的领域.

import RealmSwift

class Company: Object {
  dynamic var id = 0
  dynamic var city = 0
  dynamic var title = ""
  dynamic var address = ""
  dynamic var schedule = ""
  dynamic var workBreak = ""

  let categories = List<CompanyCategory>()
  let phones = List<CompanyPhone>()
  let sites = List<CompanySite>()
  let emails = List<CompanyEmail>()
  let services = List<CompanyService>()
  let branches = List<CompanyBranche>()

}

class CompanyCategory: Object {
  dynamic var id = 0
  dynamic var name = ""
}

所以,我有类别ID,我想知道哪些公司是指这个类别.公司可能有几个类别.

我在Java中找到解决方案 …
