I tried to build my project for distribution. I do it with help of this tutorial – http://www.idev101.com/code/Distribution/build.html
Step 3-b is to setting Developer Certificat in Code Signing sections: Debug, Release ans Distribution. But there is only Debug section in my Build Settings. How can i add 2 other? Thnx
UPD in my Project-Info-Configurations there is not “Release” configuration. How should i add it?

UPD 2 i expand rows in the very beginning. And there is only debug section

EDIT! In Xcode, navigate to your project in the file tree:
Select your PROJECT (not your target):
Select the Info tab:
Find the configurations tab, select the + button:
Select “release”.
