Pure C function calling Objective-C method?
c, function, methods, objective-c
Solution
After much experimenting, I found that the most elegant way of solving my problem was to turn my core C library into an NSObject using the .m suffix. The method of calling back and forth resolved instantly. This change DOES alter my original library, but by so little, it's manageable. So to review:
My original C file was renamed to use the .m suffix. Then I added
@interface myCLibrary : NSObject
@end
to my .h file, and added to my formerly .c file, now renamed .m.
@implementation myCLibrary
@end
Just remember that C functions aren't to be pasted between these interface / implementation declarations, below them. Only Objective-C is to go inside these statements. Once I did that, calling the C functions, and calling BACK to other C functions worked great.
Thanks for all the help regardless.
Problem
Okay, I've read half a dozen threads on this subject, but none of the solutions appear to address exact needs. Question: How does a Pure C (.c) function call a method inside a Pure Objective-C (.m) class? Every example / answer is using C inside an Objective-C (.m) method. I have a Pure C library that I have to create a simulator for, so I need to keep my Kernel in pure C and call out to my higher level emulation methods in Objective-C. Any attempt I make to create a reference and call a method fails. Square bracket notation fails as well. Creating a global var in Obj-C and trying to use that in Pure-C doesn't work, as if the namespace is segregated. Anyone done this? Here's a diagram of the flow: Obj-C UIButton CLICKED->Calls Obj-C method->Calls C function->Call Obj-C method
