Title: UIEventListener subscribe/unsubscribe
Post by: pretender on January 29, 2015, 04:37:58 AM

I was wondering if it is needed to unsubscribe onClick event for example that is subscribe to with UIEventListener?

here is what i am doing

1. UIEventListener.Get(Button).onClick += go =>
2.                     {
3.                         Debug.Log(go.name);
4.                     };
5.  
6. ...
7.  
8. UIEventListener.Get(Button).onClick -= go =>
9.                     {
10.                         Debug.Log(go.name);
11.                     };
12.  

Unsubscribe part gives me warning in Visual Studio...what is the proper way of doing this? Thanks!

You can't do that with => I'm pretty sure, as this creates a new inlined function in that part of the code. They're effectively different functions.

The only way to -= is to have a proper non-anonymous function reference for both += and -=.
