pkpass 无法通过电子邮件附件在 iOS 上打开

Question

All websites mention that Passbook passes can be sent by e-mail. But when the pass (generated by our server) is attached to an e-mail, the iOS e-mail client won't open it and write "(null)" instead. The same pass works fine on Android and also has no problems communicating with our web service. Any ideas? Google searches didn't offer any solutions.

Answer 1

Solved: There were multiple problems:

• The authentication token has to be at least 16 characters long
• I used the "Apple Inc. Root Certificate" (wrong one) instead of the "AppleWWDRCA" (correct one)
• For production the web service needs to use https

Answer 2

You get that when the pass in invalid, most likely due to it being incorrectly signed and/or the pass certificate has expired.

Drag your pass into iPhone Simulator and check the Console app to look for error in the logs.
