provisioning profile does not appear in project.pbxproj

I downloaded the sample code of LocateMe program from the developer site of Apple ( http://developer.apple.com/library/ios/#samplecode/LocateMe/Introduction/Intro.html ). After configuring properties, I tried to build and got the code sign error.

The answer accessed through the following link have been solving this problem for another source codes I downloade开发者_C百科d since now. Code Sign error: The identity 'iPhone Developer: x Xxxxx' doesn't match any identity in any profile

This time I couldn't find "PROVISIONING_PROFILE" to change its value.

I would appreciate any help very much.
