Android studio Libgdx未找到匹配的签名标识'/（？i）iPhone开发者| iOS开发'；

我会用Android libgdx填充我正在使用的应用程序，并使用robovm进行学习，但我没有识别证书

xcode首选项中的证书已正确下载，然后通常都能正常工作。。。。我所做的是因为它过期了，然后我用xCode重新下载

有人知道怎么解决这个问题吗？多谢各位

我在这里找到了解决方案：

它说：

1. Open up Keychain Access.
2. Show expired certificates by going to View > Show Expired Certificates.
3. Navigate to the System keychain and delete the expired WWDR Certificate.
4. Download the new WWDR Certificate [here][1] and import it into your keychain.

我不必做第4点。新证书已经存在
