小编Sri*_*i..的帖子

我用谷歌搜索了很多，我也给 Adcolony
支持发送了一封邮件（http://support.adcolony.com/customer/portal/emails/new），但我仍然没有收到他们的任何邮件。

         I got ads perfectly, but after some time onwards im not getting any ads and also
    getting error message like "**There is currently no fill for zone  zone id with slot
     0**" 
    and also **"Video ad requested but not served in zone zone id with slot 0"**  

   Please assist me, How to get ads on every button tap on ios app.             

我是Realm SWift的新手.我希望在Swift3.0中实现一对多的关系

我有文件夹列表,每个文件夹可能有子文件夹列表.所以我创建了两个像下面这样的relam文件.

文件夹领域类

 class FolderRealm: Object {

    dynamic var folderName : String?
    dynamic var createdDate : Date?
    let subFolders = List<SubFolderRealm>()
 }

SubFolder领域类

 class SubFolderRealm: Object {

   dynamic var subFolderName : String?
   dynamic var createdDate : Date? 

 }

对于添加文件夹,我使用了以下代码行

let folder : FolderRealm  = FolderRealm()
folder.folderName = searchBarObj.text!
folder.createdDate = Date()
 try! realm.write {
   realm.add(folder)
 }

我有疑问,如何将子文件夹数据添加到文件夹和子文件夹领域？
