CodeSign error: a valid provisioning profile is required

"CodeSign error: a valid provisioning profile is required for product type 'Application' in SDK 'Device - iPhone OS 2.2"

This error will appear when you update your provisioning profile in iPhone SDK 2.2
or after the expiration of developer certificate and that you have a new provisioning profile from the developer portal

This is the solution (which is modified from http://www.furmanek.net/54/iphone-sdk-22-codesign-error/)

Suppose you have copied your provisioning profile called "iPhone_Development.mobileprovision" to the Library folder and build & go an old iPhone project called "MyApp", and this annoying error appears

(1) cd ~/Library/MobileDevice/Provisioning\ Profiles/

(2) find out the UUID of the provisioning profile
strings iPhone_Development.mobileprovision | grep ".*-.*"

output is like this
xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx

(3) copy that UUID between the string tag

(4) close xcode and go to your project
cd ~/Projects/MyApp/MyApp.xcodeproj

(5) Use a text editor to open the project.pbxproj
find the string PROVISIONING_PROFILE

paste the UUID that you copied from step (3) and put it in both Debug and Release Sections (do multiple finds) for the following line
e.g.
PROVISIONING_PROFILE = "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx";

(6) Launch XCode and open the project and build & go again
