這一封是填完申請表之後收到的，大致意思就是蘋果已經收到了我的申請，會盡快處理巴拉巴拉。不過不知道為啥，這一封郵件我收到了三遍，可能是蘋果那裡自動回覆的問題。

這一封是申請成功的郵件，表示我的賬號已經成功具備了使用該模組的許可權，蘋果在郵件中詳細給出了官方文件地址和出問題之後的反饋方式，貼心。
Please include the line below in follow-up emails for this request.
Follow-up: XXXXXXXXX
Hi,
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.
<https://developer.apple.com/account/>
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.
<https://developer.apple.com/library/ios/technotes/tn2415/_index.html#//apple_ref/doc>
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 <https://forums.developer.apple.com/community/core-os/networking> or open a DTS Technical Support Incident following the steps posted here: https://developer.apple.com/support/technical/submit/
Thank You.

然後到這裡就表示申請成功了，其他資訊包括申請失敗／申請無回覆／這樣申請可不可以之類的問題，我也不知道該怎麼辦，全過程都在上面了，沒有額外流程，沒有給蘋果回覆郵件，沒有打電話，啥都沒，另外我是個人賬號（無鄧氏編碼的那種），所以恕不一一回復。
如有任何智慧財產權、版權問題或理論錯誤，還請指正。
