As mentioned, you can use the Objective-C runtime API to retrieve the instance variable names:

unsigned int varCount;Ivar *vars = class_copyIvarList([MyClass class], &varCount);for (int i = 0; i < varCount; i++) {    Ivar var = vars[i];    const char* name = ivar_getName(var);    const char* typeEncoding = ivar_getTypeEncoding(var);    // do what you wish with the name and type here}free(vars);

How do I list all fields of an object in Objective-C?
