关于通过核心数据自动生成代码的快速问题

Question

I have two entities Company and Employees. Company has a 1-to-many relationship with employees. An almost exact question was asked here however it doesnt answer my question :(. Like in that question, xcode in Company.m generates 4 almost exactly the same methods. However, the prototypes are not included in Company.h which leads me to believe that this is either

• An error and that company.h requires the 4 prototypes for the void functions described in.
• Intended and those 4 methods are only usable in the .m file? If so how to add many employees to a company.

Standing by for any clarifications. Thanks!

Answer 1

Typically I just set the company on the employee when creating the employees.

[newEmployee setValue:company forValue:@"company"];

this will trigger the relationship both ways and add the employee to the companies set of employees.

or since you've subclassed it.

newEmployee.company = company;
