Solution for failure of all certificates in the iOS-key string (invalid issuer of the certificate), ios-Key

Solution for failure of all certificates in the iOS-key string (invalid issuer of the certificate), ios-Key

Today, I used Xcode to package the IPA file to my colleagues. When the result showed that the import was prompted, I was prompted for the certificate missing. After finding the file for a long time, I did not find any problem. Then I opened the key string and found that all the certificates were invalid !!! Scared to death ~~~~ (>_< )~~~~

Then, process it.

1. Open the key string

2. For example, double-click or right-click the certificate information.

3. Package again. The package is successful.
