证书过期问题

你可能接收过这种苹果技术支持的邮件，这就是证书过期造成的。

Dear Bin Wang, 

  Apple Developer Program Support has revoked your certificate, so it is no longer valid. 

  Certificate: iOS Distribution Team Name: *******************.

 Any provisioning profiles that include this certificate are no longer valid and must be regenerated for future use. 

Best regards, Apple Developer Program Support
