Is it possible to start a coroutine using a button from the new UI system (4.6)

Question

I tried Starting a simple coroutine using a button created with the new UI system, but everytime I have a yield in my fuction it stop appearing in the button's function selector drop down menu in the inspector, the coroutine is a really simple :

while(true) { do something; yield }

Is there something special i need to do or is it just impossible to start a coroutine with a button using the new UI system ?

You cannot directly called the coroutine since your method needs to return void but you can just use a wrapper.

 public void Wrapper(){
     StartCoroutine(MyCoroutine());
 }
 private IEnumerator MyCoroutine(){
     yield return null;
 }

As a side note you may know but in case, if you wish to prevent multiple calls.

 private bool isRunning = false;
 public void Wrapper(){
     if(isRunning == false){
        StartCoroutine(MyCoroutine());
     }
 }
 private IEnumerator MyCoroutine(){
     isRunning = true;
     // Do your stuff over multiple frames
     yield return null;
     isRunning = false;
 }

After you've added a UI Button component to an object, you should go into the button's inspector and drag the gameObject into the button component. After the gameObject is referenced, you can select a method from a dropdown menu. Make sure your method is public.
