Difference between code signing target and project

问题

I noticed that in Xcode I can set the Entitlements and Code signing settings both on:

• the Project (double click on the top item in Groups & File, which has the name of the project)
• the Target (under Targets, double click on your project name).

What's the difference between these two? I know that with header paths, one tends to override the other (without warning of course...).

回答1:

Target settings override Project settings. Project settings are valid for all Targets where the setting has not been overridden.
