解决方法:
1. 进入苹果开发者后台-> Certificate -> Distribution
2. 删除已过期的 Current Distribution Certificate -> "Revoke"
3. 然后再按官方上传证书的方法再操作一遍:
Generate a Certificate Signing Request (CSR) with a public key In your Applications folder, open the Utilities folder and launch Keychain Access. Choose Keychain Access > Certificate Assistant > Request a Certificate from a Certificate Authority. In the Certificate Information window, enter or select the following information: In the User Email Address field, enter your email address In the Common Name field, enter your name In the Request is group, select the Saved to disk option Click Continue. The Certificate Assistant saves a Certificate Signing Request (CSR) file to your Desktop. The public/private key pair will be generated when you create the Certificate Signing Request (CSR) if you use the Key Chain Assistant to create the CSR. Submit the CSR through the Provisioning Portal. Click the Development tab Upload the certificate by choosing the file Click Submit4. 再进入Distribution Provisioning Profiles 对需要的进行编辑 状态就回来了“Active”
5. 再下载使用就ok了
