title: using native objective-c method for C callbacks
body: <p>I want to callback an objective c method from c.</p>
  
  <pre><code>//c 
  int gameEngineCallback(int buttontype,void (*callback)(void))
  
  //using above function
  gameEngineCallback(roundButton,callback);
  
  //this works fine but I want to call objective c native method instead of this
  static void callback(void){
  
  }
  </code></pre>
