somewhere in second.m and assuming main.h/m defines a "Main" class
在second.m中的某处,假设main.h / m定义了一个“Main”类
Main *m = [[Main alloc] init];
NSString *mString = [m ok];
//Do Stuff
[m release];
However, based on the fact that your example returns void and not NSString, I think you have some basic knowledge to gain first. I'm guessing you don't understand Interfaces and Implementations yet, etc.
但是,基于您的示例返回void而不是NSString的事实,我认为您首先获得了一些基本知识。我猜你还不了解接口和实现等等。
I would suggest starting with a good basic tutorial.
我建议从一个很好的基础教程开始。

create an instance of main.m in second.m, then then using the created instance you can easily access its own variable. i support MaskPowell's answer.
在second.m中创建main.m的实例,然后使用创建的实例,您可以轻松访问自己的变量。我支持MaskPowell的答案。
