Pure C function calling Objective-C method?

Question

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) fun

Answer 1

I hope i understand you correctly!

You can do this via callback-function.

In you C file use this:

Define the callback-type

eventcallback g_callback;

Implement callback-class (executed by objective-c code)

void comm_set_callback(eventcallback callback){
   g_callback = callback;
}

in objective-c:

Set the callback (i.e.: in viewDidLoad())

comm_set_callback(&testfkt);

C-Method called from extern C-function

void testfkt(){
 [refToSelf testmethod];
}

Objective-C Method called from C-Method testfkt

-(void)testmethod{
   ...
}
