问题描述
我正在为我的班级编写单元测试.它具有在类扩展中声明的私有属性.现在，我想在我的单元测试中提供对其中一些属性的访问，因此我必须从实现文件中提取类扩展到一个单独的头文件中，我可以在我的单元测试中导入它.当类扩展名与实现 (.m) 分离时，类扩展名的正确文件命名约定是什么?
I'm writing unit tests for my class. It has private properties declared in the class extension. Now, I would like to provide access some of these properties in my unit tests, hence I have to extract the class extension from the implementation file into a separate header file that I can import in my unit tests. What is the proper file naming convention of class extension when it's separated from the implementation (.m)?
// MyClass.h
@interface MyClass : NSObject
@end
// MyClass.m
@implementation MyClass
@end
// MyClass+???.h
@interface MyClass()
@property (nonatomic, strong) NSString *myString;
@end
推荐答案
Objective C 没有标准的代码约定.Apple 的文档只描述了几个简单的时刻.最常用的方法是使用
There is no standard code convention for Objective C. Apple's documents describe only few simple moments. The most common approach is to use
MyClass_Private.h
用于扩展和
MyClass+Private.h
用于类别.
