Try this:

create an empty object in your scene
Attach your script to it (Drag and drop your script into that object inspector to create a scrip component)

in button

Drag and drop the object created above in the Object field on the OnClick event (and not the script itself from your Project tree)

That should work.

Thanks VincentZgueb! It seems like there's still a bug here, but your suggestion did work for me. I'd +1 but it says I don't have enough reputation :(

This didn't work for me. In fact, that's exactly what I had done, but my public methods for the script don't show on the drop-down. It seems it only shows the native GameObject methods. Has anyone had the same problem?

Ok, I figured it out. I hadn't noticed that the methods for On Click have to return void, and only accept int, float, bool, string, and Object parameters. My method received an enum, so I had to change it.

quick side note, if your function still doesn't appear, maybe it is because it has 2 or more Parameters in it, it seems unity only support 1 parameter at a time for function in button interface.

I had the same issue - here is what worked for me.

I was dragging the script directly to the button, which doesn't work. I needed to drag the object which contains the script onto the button!

After i did that, the functions showed up!

I have your answer! You need to make sure that the function that your trying to put on the button is a public function. If that doesnt work right away just re reference you object containing the script :)

Make sure your method is void, public and has no more then 1 parameter.

examples:

 public void Methodname()
 {
 
 }
 
 public void Methodname(string param)
 {
 
 }
 
 public void Methodname(bool param)
 {
 
 }

Also make sure your class and/or method is not static. Attach the script to a GameObject and drag the gameobject onto the onClick event in the inspector. Select the method you wish to execute on the click.
