How to resolve one to many relationships in master data in iOS 4.0

Question

Now I am developing an application on iPhone OS with basic data, but when I add the kernel code to the application, Xcode throws an error that requires iOS 5.0 or later for the "to-many relationship entity.relationship" parameter

How to deal with this problem? or is there another way to replace low cost master data.

Some information: Basic SDK: iOS 5.0 Purpose of deployment: iOS 4.0

thanks

Answer 1

He does not complain about the relationship, he complains about the option that you set for the relationship. Most likely, this is because you selected the Ordered option for the relationship, which is only supported in iOS 5 and above.
