如果您的所有证书都出现“此证书的颁发者无效”错误，那么请执行以下步骤。

步骤:

Open Keychain and Click on Login -> All Items from the left panel. Now, Click on View -> Show Expired Certificates from the top navigation menu. Now search for "Apple Worldwide Developer Relations Certification Authority" and delete expired certificates. After deleting expired certificates, visit the following URL and download the new certificate, https://developer.apple.com/certificationauthority/AppleWWDRCA.cer. Double click on the newly downloaded certificate, and install it in your keychain. Double check: List expired certificates by following step number 3. Now you have a valid "Apple Worldwide Developer Relations Certification Authority" having expiry date 2023-02-07.

如果您是从Fastlane来到这里的，那么这个片段可能会修复您的CI部署。在签名之前执行它。

 apple_intermediate_certificate_path = "/tmp/AppleWWDRCAG3.cer"
`curl https://www.apple.com/certificateauthority/AppleWWDRCAG3.cer --output #{apple_intermediate_certificate_path}`

other_action.import_certificate(
  certificate_path: apple_intermediate_certificate_path,
  keychain_name: YOUR_KEYCHAIN_NAME,
  keychain_password: YOUR_KEYCHAIN_PASSWORD
)

当地日期尽量早于2月14日。对我有用!不能完全解决问题，只能暂时解决问题。

下载https://developer.apple.com/certificationauthority/AppleWWDRCA.cer 双击安装到Keychain。 在钥匙串应用程序中选择“查看”->“显示过期证书”。 确认选择“证书”类别。 从“登录”标签和“系统”标签中删除过期的Apple全球开发者关系证书颁发机构证书。

以下是苹果的答案。

Thanks for bringing this to the attention of the community and apologies for the issues you’ve been having. This issue stems from having a copy of the expired WWDR Intermediate certificate in both your System and Login keychains. To resolve the issue, you should first download and install the new WWDR intermediate certificate (by double-clicking on the file). Next, in the Keychain Access application, select the System keychain. Make sure to select “Show Expired Certificates” in the View menu and then delete the expired version of the Apple Worldwide Developer Relations Certificate Authority Intermediate certificate (expired on February 14, 2016). Your certificates should now appear as valid in Keychain Access and be available to Xcode for submissions to the App Store.

您需要从右上角搜索栏搜索World，删除过期的证书。确保您选择了登录和所有项。

我想我想明白了。我导入了新的WWDR证书，该证书将在2023年到期，但我仍然在构建过程中遇到问题，我的开发人员证书仍然显示无效的发行者错误。

在keychain访问方式下，执行“查看->显示过期证书”。然后在您的登录钥匙串突出显示过期的WWDR证书，并删除它。 我的系统钥匙串中也有同样过期的证书，所以我也把它删除了(这很重要)。

在从登录和系统密钥链中删除过期的证书后，我能够再次为分发版构建。
