Code signing error on iOS Simulator

Question

I am using XCode 3.2.6 with iPhone Simulator 4.3 but when i run build and run this app on iPhone Simulator it throws error

Code Sign error: The identity 'iPhone Developer' doesn't match any valid certificate/private key pair in the default keychain

I got to know about this error when i am using Interface Builder->Build and go to XCode then it shows error and when compiled using XCode it just shows a blank screen on iPhone Simulator.
