如何在测试中将父类中的扩展函数用于我自己的子类？
的一些扩展中导入了标头数据。
我有一个从 NSTreeController 派生的类，名为 CSMCustomTreeController，并从 NSTreeController CSMCustomTreeController.h
#import "NSTreeController_Extensions.h"
@interface CSMCustomTreeController : NSTreeController {
...
扩展已定义 NSTreeController_Extensions.h：
#import "NSTreeController_Extensions.h" #import "NSTreeNode_Extensions.h" #import "NSIndexPath_Extensions.h" #import "NSArray_Extensions.h" @implementation NSTreeController (ESExtensions) ...
我可以使用所有定义的我的正常目标中来自 ESExtensions 的函数，但在我的测试用例中，似乎我的子类对扩展函数一无所知...:(
只有我的测试用例被添加到测试目标...
有人有线索吗？
I have a class derived from NSTreeController named CSMCustomTreeController and imported the header data from some Extensions of NSTreeController
CSMCustomTreeController.h
#import "NSTreeController_Extensions.h"
@interface CSMCustomTreeController : NSTreeController {
...
The Extension ist defined NSTreeController_Extensions.h:
#import "NSTreeController_Extensions.h" #import "NSTreeNode_Extensions.h" #import "NSIndexPath_Extensions.h" #import "NSArray_Extensions.h" @implementation NSTreeController (ESExtensions) ...
I can use all the defined Functions from ESExtensions in my normal target, but in my TestCases it seems that my subclass doesn't know anything about the extension functions... :(
Only my testcases are added to the Test-Target...
Anybody a clue?

您应该确保两个标头（
CSMCustomTreeController.h和NSTreeController_Extensions.h）都导入到您的测试用例类中。如果您不导入包含类别的标头，测试用例类将无法找到您的类别方法。
You should make sure that both headers (
CSMCustomTreeController.handNSTreeController_Extensions.h) are imported into your test case class.If you don't import the header containing the category, the test case class will not be able to find your category methods.
