I have a core data model with the following info:
Entity: CourseSubjects
Attributes:
-account_id
-course_code
-course_id
-name
I need to be able to select Only one piece of data from that database which has the field course_id matching what I want. How would I be able to select only one field from this database which has the course_id?
Thanks
Read “Introduction to Predicates Programming Guide” and the NSPredicate documentation. In short, you’ll create a predicate for course_id and then execute a fetch using that predicate.
