在国内, 积分墙以及各大助手(爱思助手, 91苹果助手, XY苹果助手, PP助手, 快用助手)等业务领域都在使用，苹果对证书的使用越来越严格。简单的分析一下，证书被封的原因。
一般证书被封会收到两封邮件。
1. Your iOS Development certificate has been revoked.
Dear Ming Cai,
You have revoked your certificate, so it is no longer valid.
Certificate: iOS Distribution
Team Name: Shaanxi Dasheng Pharmaceutical Tech Co., Ltd
Any provisioning profiles that include this certificate are no longer valid and must be regenerated for future use.
Best regards,
Apple Developer Program Support
2.Notice of Termination
Dear Ming Cai:
This letter serves as notice of termination of the iOS Developer Enterprise Program License Agreement (the “iDEP Agreement”) and the Registered Apple Developer Agreement (the “Registered Developer Agreement”) between you and Apple, effective immediately. Defined terms used herein have the same meaning as in the iDEP Agreement.
Pursuant to the iDEP Agreement Section 8.b, you agreed that Apple may revoke the digital certificate issued to You if, at any time, Apple has been notified or otherwise has reason to believe that Your Internal Use Application, Pass or any OS X Website Push Notification violates, misappropriates, or infringes the rights of a third party or of Apple. Apple has good reason to believe that You violated this Section of the terms of the iDEP Agreement.
Apple may terminate your status as a Registered Apple Developer at any time in its sole discretion and may terminate you upon notice under the iDEP Agreement for misleading, fraudulent, improper, unlawful or dishonest acts relating to that agreement. We would like to remind you of your obligations with regard to all software and other confidential information that you obtained from Apple as a Registered Apple Developer and under the iDEP Agreement. You must promptly cease all use of and destroy such materials and comply with all the other termination obligations set forth in Section 12.3 of the iDEP Agreement and Section 8 of the Registered Developer Agreement.
This letter is not intended to be a complete statement of the facts regarding this matter, and nothing in this letter should be construed as a waiver of any rights or remedies Apple may have, all of which are hereby reserved. Finally, please note that we will deny your reapplication to the iOS Developer Enterprise Program for at least a year considering the nature of your acts.
Sincerely,
Apple Inc.
