Code-signing certificate in keychain

heya,
my unity remote was working fine then poof. I get this error and i have now deleted the key that i once had.
Can someone lend a hand?

CodeSign error: Code Signing Identity ‘iPhone Developer’ does not match any code-signing certificate in your keychain.

much appreciated,
cp

you need to drag and drop the CodeSign to xcode to install it

shoot. i am all thumbs with this.

i have a certificate: developer_identity.cer
with a common name : iPhone Developer: Christopher Powell
and three provisioning files.

im not really sure where and how to drop a sign code.

i do know that i deleted my key that was workign at one point.

thanks lots for getting back to me.
Your games are creative. nice work.

thanks lots,
