二. 邮件往来

申请表格填写完成后收到如下系列邮件，发件人均为 networkextension@apple.com。

1. Acknowledgement of your Network Extension framework request -Follow-up: XXXXXXXXX

这一封是填完申请表之后收到的，大致意思就是苹果已经收到了我的申请，会尽快处理巴拉巴拉。不过不知道为啥，这一封邮件我收到了三遍，可能是苹果那里自动回复的问题。

Thank you for requesting information about the Network Extension framework. If you have already filled out the request questionnaire then your request will be addressed at our earliest convenience. Otherwise please visit 
     and enter the required information.Regards,Developer Technical SupportApple Worldwide Developer Relations复制代码

2. Re: Requesting information about the Network Extension framework

这一封是申请成功的邮件，表示我的账号已经成功具备了使用该模块的权限，苹果在邮件中详细给出了官方文档地址和出问题之后的反馈方式，贴心。

Please include the line below in follow-up emails for this request.Follow-up: XXXXXXXXXHi,Thanks for your interest in the Network Extension APIs.We added a new template containing the Network Extension entitlements to your team.To use these special entitlements you must create a new provisioning profile in the Certificates, Identifiers & Profiles section of the developer web site.
    When you create a Development or Distribution provisioning profile for your Team ID, after selecting the devices to be included in the profile, you should see a new page entitled “Do you need additional entitlements?”.  Select “Network Extension” from the Entitlements popup to include the Network Extension framework entitlements in your new profile.Once you’ve finished generating the profile, you can use it in Xcode like any other manually-generated profile.IMPORTANT: If you have problems getting this to work, read Technote 2415 “Entitlements Troubleshooting” for troubleshooting steps.
    
     You may also want to read “Debugging Entitlement Issues”, which is specifically focused on the special entitlements used by the Network Extension framework.
     
      NOTE:  This address is only for requesting Network Extension entitlements.   If you need additional support please visit the Apple Developer Forums at 
      
        or open a DTS Technical Support Incident following the steps posted here: https://developer.apple.com/support/technical/submit/Thank You.Apple Developer Technical Support复制代码

三. 其他

然后到这里就表示申请成功了，其他信息包括申请失败／申请无回复／这样申请可不可以之类的问题，我也不知道该怎么办，全过程都在上面了，没有额外流程，没有给苹果回复邮件，没有打电话，啥都没，另外我是个人账号（无邓氏编码的那种），所以恕不一一回复。
