every time when i open xcode project for ios mobile app it show following message:
"Your account already has a signing certificate for this machine but it is not present in your keychain. To create a new one, you must first revoke the existing certificate."
and Every time create new certificate. it happnes after Developer account member ship is renewed.
please give me any solutions.
This is saying that you have a signing certificate already but you have to put that certificate in your keychain. So if you have that certificate stored anywhere then please put that certificate in your laptop keychain. Otherwise if you dont know where is your certificate stored then you have only one option. you have to revoke(delete) the certificate from appledeveloper.com and create a new one then store it in your device keychain.
If the above answer didnt help you, I think you might miss some Apple Intermediate Certificates in your keychain...
Go to the Apple PKI, install the missing ones in the Apple Intermediate Certificates section.
Let me know if it helped
