目标C - 2 .m文件用于一个.h文件? [英] Objective C - 2 .m files for one .h file?
问题描述
我的问题是,我会知道如何为一个对象类使用2个.m文件也用于一个标题(.h)
我有一个很棒的方法20000 +行,我会,这种方法独立于.m文件和其他.m文件中的其他方法。我已经完成了,但是我得到错误,方法不在一个.m文件中。我得到一个链接错误,但我可以删除链接错误,如果我删除第二个.m文件。
是否可以为一个头创建2个.m文件?
如果是,请告诉我怎么做?
方法:您可以将您的方法分成两个不同的类别:
-
或者您可以尝试在第一个文件中包含第二个
.m
文件:
// - MyClass1.m
@implementation MyClass
< first part>
#includeMyClass2.m
@end
you could split your methods into 2 different categories:
//-- MyClass1.m @implementation MyClass (part1) @end //-- MyClass2.m @implementation MyClass (part2) @end
I defined 2 categories for symmetry reason; of course you also need a "base"
@implementation
of your class (i.e., without the category specifier); you can choose whether you define a "base" and andextension
category, or "base" and two categories, etc...or you might try including the second
.m
file inside of the first one://-- MyClass1.m @implementation MyClass <first part> #include "MyClass2.m" @end
pre>
// - MyClass1.m
@implementation MyClass(part1)
@end
// - MyClass2.m
@implementation MyClass(part2)
@end
为了对称原因我定义了2个类别;当然你也需要你的类的base @implementation
(即没有类别说明符)。你可以选择是否定义基础和扩展
类别,或者基本和两个类别等等。
两者都应该有效。
更不用说重构类的可能性,这将是最好的选择。
My question is, that I would know how to use 2 .m files for one objectclass also for one header (.h)
I have a big method with 20000+ lines and I would, that this method stand alone in a .m file and the other methods in the other .m file. I have done it, but I get errors, that the methods aren not in the one .m file. I get a link error, but i can remove the link error if i delete the second .m file.
Is it possible to create 2 .m files for one header ?
If yes pleas tell me how?
You have several approaches:
Both should work.
Let alone the possibility of refactoring your class, which would be the best option.
