Hi Everyone, Been learning to use core data, all was going well until I reached the One to Many relationship point. Can't seem to find any good simple tutorial that implements a One to Many Relationship, If Anyone knows of one, then that would be great.
I am experimenting with a simple core data example.
Entity A = carMake: makeName = String.
Entity B = carModel: modelName = String.
Relationship: One to Many, One carMake has many carModels.
I have 4 View controllers:
-MakeVC
-AddMakeVC
-ModelVC
-AddModelVC
I have managed to code the first two view controllers that deal with listing carMake and adding carMake, My problem occurs with the ModelVC and AddModelVC.
As i do not know how i should be passing the selected carMake and as what type.
Q. How to pass selected carMake to ModelVC.
Q. How add a carMake to a carModel.
Q. How to fetch and list only the carModels for the carMake selected.
Thank you for any help, Again is any one knows of a good tutorial i can follow then that is all thats really required.
