问题描述
请查看以下屏幕截图
please look at the following screenshot
如您所见，有两个证书。
As you see there are two certificates. All are mine, with maching user's ID and common name.
每当我构建应用程序并在设备的Xcode中启动它时，我收到致命的，这个证书是重复的。因此，我删除过期的应用程序并重新启动应用程序 - 它正在设备上安装和调试，没有任何问题。
Whenever I build the application and launch it in Xcode for device I receive the fatal, that this certificate is duplicated. So I delete the expired one and launch the application again - it's being installed and debugged on device without any problems.
但是当我启动其他项目或重新启动，
But when I launch other project or reboot that expired certificate is shown in the keychain again and again and it's becoming a little bit annoying.
是什么原因导致过期的证书被读取到钥匙串？
What causes that the expired certificate is being readded to the keychain? How can I dissable it?
推荐答案
这是Xcode 4中的一个已知错误。Xcode会在每次重新启动时恢复已删除的配置文件。有关详情，请参见。我也有问题，但仍然不知道如何解决它。
This is a known bug in Xcode 4. Xcode restores the deleted profile on restart everytime. See http://openradar.appspot.com/9173280 for more information about this. I have the problem too, but still don't know how to solve it.
