Question

Is there a way to get the call stack? lets say i have a function that gets called by many other functions, but I need to know who called it.

Thanks

Of course there is. If you can use the Cocoa framework:

NSLog(@"%@", [NSThread callStackSymbols]);

(Documentation.)

If you can’t use it:

#include <execinfo.h>

int size = 256;
void *stack[size];
size = backtrace(stack, size);

char **syms = backtrace_symbols(stack, size);
for (int i = 0; i < size; i++) {
    printf("Frame #%d: %s\n", i, syms[i]);
}
free(syms);
