如何删除xcode中的多余证书

Answer 1

Point is, it is the private key that xcode looks for for the certificates that you already have. Since you have a private key, xcode lists that as a available option for signing. So, its the private key that you want to delete and not the certi. So go to Keys section in the keychain access, find the culprit key, and shoot it.

最后在keychain access 中的密钥 section中将多余的private key 删除就可以了。 这下重启计算机后，多余的证书就不会在回来了。

Answer 2

到钥匙串里删除试试
