1) Add the build engineer to the development team with the role of Admin through the Member Center. For more information on defining team roles, see Managing Your Team. The Admin role is required to manage the team distribution certificate.
2) If the distribution build will be submitted to the App Store, add the build engineer to the team users on iTunes Connect with the role of Technical User. This allows the build engineer to log into iTunes Connect with their own credentials while submitting the app. Skip this step if the build is being used for Ad Hoc beta testing. For more info about the Technical User role in iTunes Connect, see Managing Users in the iTunes Connect Developer Guide.
3) The build engineer should then…
Create a new distribution certificate according to Creating Your Certificates. If the team distribution certificate already exists, it must be revoked and recreated by the build engineer according to Re-Creating Certificates and Updating Related Provisioning Profiles.
Create a distribution profile using the steps in Creating Store Provisioning Profiles.
Download and install the distribution provisioning profile by dragging it onto the Xcode or iTunes icons on the dock.
Define a Bundle Identifier in Xcode that is compatible with the App ID for the app using the steps in Setting the Bundle ID.
Assign the distribution provisioning profile to the 'Release' Code Signing Identity with the Xcode project Target level Build Settings.
This Q&A is exclusively for iOS App Store apps. The process within this document should not be followed for the Enterprise Developer Program. Please consult Apple DTS with any questions before leveraging this document, or if you are unsure of your developer program type.
A single email address has access to only one iTunes Connect account, unlike the Member Center, which supports multiple teams per Apple ID. Therefore the build engineer must supply a new unique email address that is not already associated to another iTunes Connect account.
一个email地址只允许链接一个iTunes账户，作为一个bulid enginner 必须有一个email，这个email没有链接多个iTunes账户。好了就这么多了。有不懂的大家一起探讨
