How does Xcode know which profile the application belongs to?

I have been wondering about how does xcode link the provisioning profile to a particular application.

For example, I install profile named 'myprofile' in the organizer and go to the project name 'newapp' and say build and go.

The application 'newa开发者_如何学Gopp' is installed fine on the iphone but how do i know if there is a link between 'newapp' and 'myprofile'.

What happens if i change my app name and again say build and go?

This is what i do:

1. Login to my account.

2. Create a new app id: 'first'

3. Use existing device: 'myiphone'

4. enter the profile name: 'myprofile', download it

5. install it inside organizer. (Till this point no application is assigned to the profile)

6. Now go to my project: 'newapp' just say build and go and app runs on the device.

I never selected a profile and said assign the app to this profile so... How can i say that 'myprofile' is tied to 'newapp'?

Thanks

Its your app bundle identifier from the project-info.plist file that is mapped to a profile. You can ofcourse have wildcard characters and use a profile to build multiple apps.

You can manually set which profile an app will use in the build settings (under "Code Signing Identity"). The default for this is automatic which will match based on your app identifier (com.example.appname).
