问题的出现如下, 常常用一个账号在多台mac上面进行开发的朋友可能会遇到.

The identity used to sign the executable is no longer valid.Please verify that your device’s clock is properly set, and that your signing certificate is not expired.(0xE8008018).

解决方案有两种

1.重启Xcode(如果不行,用下种方式)

2.解决方案在Xcode内部:

Preferences –> Accounts –> View Details

点击你的开发者账号,没有的话创建一个, 把所有证书下载下来

点击Download all按钮 (Xcode 7)

PS:

有时候你可能还需要删除无效的证书.
