Delegates not working on iOS

Hi Unity Peeps,

So I have the following code that works fine in the Editor but not on iOS and was wondering if someone could tell me why and point me towards a possible solution. Basically the MyCallBack function is not getting called on an iOS device but does in the editor.

 public class MyClassOne : MonoBehaviour {
 
  MyClassTwo myClassTwo;
 
  void Start ()
  {
   myClassTwo = new MyClassTwo();
 
   MyFunction();
  }
 
  void MyFunction ()
  {
   myClassTwo.MyFunctionInClassTwo(MyCallBack);
  }
  
  void MyCallBack (bool isSuccessful)
  {
   if(isSuccessful)
   {
     Debug.Log(":)");
   }
   else
   {
    Debug.Log(":(");
   }
  }
 }
 
 public class MyClassTwo : MonoBehaviour {
 
  public delegate void MyDelegate(bool isSuccessful);
  private MyDelegate myDele;
 
  public void MyFunctionInClassTwo (MyDelegate functionToCall)
  {
   myDele = functionToCall;
   MySecondFunctionInClassTwo();
  }
 
  void MySecondFunctionInClassTwo ()
  {
   myDele(true);
  }
 
 }

Hmm.I don't have an IOS device but i can certainly spot something wrong here.You should never create a new object which inherits from $$anonymous$$onoBehavior.Ins$$anonymous$$d you have to get it's component.$$anonymous$$aybe you can try this:

 public class $$anonymous$$yClassOne : $$anonymous$$onoBehaviour
 {
     void Start()
     {
         gameObject.GetComponent<$$anonymous$$yClassTwo>().$$anonymous$$yFunctionInClassTwo($$anonymous$$yCallBack);
     }
 
     void $$anonymous$$yCallBack(bool isSuccessful)
     {
         if (isSuccessful)
         {
             Debug.Log(":)");
         }
         else
         {
             Debug.Log(":(");
         }
     }
 }
 
 public class $$anonymous$$yClassTwo : $$anonymous$$onoBehaviour
 {
     public delegate void $$anonymous$$yDelegate(bool isSuccessful);
     private $$anonymous$$yDelegate myDelegate;
 
     public void $$anonymous$$yFunctionInClassTwo($$anonymous$$yDelegate functionToCall)
     {
         myDelegate = functionToCall;
         myDelegate(false);
     }
 }

Place the two classes separately in one game object and maybe you can post back if it works.

thanks, i am actually doing the equivalent of that in my real code, this was just something i bashed out to show my situation, in reality the two classes are on separate objects and there both singletons.
