Sign app in xcode with ios5

Question

I face a problem while I sign the app with ios sdk5, this problem I have never faced before ...

error message as follows:

iPhone Distribution: iApp: ambiguous (matches "iPhone Distribution: AppDever" 
in /Library/Keychains/System.keychain and "iPhone Distribution: AppDever" in 
/Users/icoco/Library/Keychains/login.keychain)
Command /usr/bin/codesign failed with exit code 1

I often import the certificate file into 'login' and 'system' , but now it seem report error ...

anyone can give help ? thanks

Answer 1

Sounds like you imported the certificate into the system keychain and your user one. I'd try removing it from one of them.
