核心数据 - 如何生成CoreDataGeneratedAccessors？ [英] Core Data - how to generate CoreDataGeneratedAccessors?

问题描述

我已经浏览了苹果开发网站，google和堆栈溢出来找出CoreDataGeneratedAccessors背后的基础知识。

I've gone through apple dev website, google and stack overflow to figure out the basics behind CoreDataGeneratedAccessors.

我正在使用Xcode 4.2和核心数据。我正确地创建了实体及其关系，包括逆。

I'm using Xcode 4.2 and core data. I created entities and their relationships properly including inverse.

以下代码失败：

    self.remdetail = [NSEntityDescription insertNewObjectForEntityForName:@"RemDetail" inManagedObjectContext:context];
    [rem addRemDetailObject:remdetail];  --> I'm trying to add rem detail to rem object

因为没有自动生成的访问方法，我将以下代码手动放在NSManagedObject子类之一中。当我为我的实体创建NSManagedObjects时，未生成以下代码。我尝试通过浏览一些文章和建议自动生成访问器，如Xcode copy&粘贴等但没有生成以下代码。

because there are no accessor methods generated automatically, I put the following code manually in one of the NSManagedObject subclass. The following code was not generated when i created NSManagedObjects for my entities. I tried to generate accessors automatically by going through few articles and suggestions like Xcode copy & paste etc but nothing is generating the following code.

in rem ManagedObject - >

in rem ManagedObject -->

@interface Rem (CoreDataGeneratedAccessors)
- (void)addRemDetailObject:(RemDetail *)value;
- (void)removeRemDetailObject:(RemDetail *)value;
- (void)addRemDetail:(RemDetail *)value;
- (void)removeRemDetail:(RemDetail *)value;
@end

有谁知道如何生成CoreDataGeneratedAccessors？

does anyone know how to generate CoreDataGeneratedAccessors?

谢谢，
Rama

Thanks, Rama

推荐答案

你检查了开关To-Many Relationship 在关系属性中？

Have you checked the switch "To-Many Relationship" in the relationship properties?
