Xcode Code Sign error: The identity 'iPhone Developer' doesn't match

i tried to compile by iphone app in xcode and i got this

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

how do i get开发者_JAVA技巧 rid of it? i dont plan on selling anything on the app store just yet cause i just started with objective-c. do i have to register with the dev netwrok even though? there has to be a way around it. its a dumb thing..

thanks.

If you don't need to use an actual device you can simply switch to using the simulator

Project -> Active SDK -> iPhone Simulator

Otherwise you'll be needing a developer certificate from Apple
