UIButton inspector onClick not support function with basic type param?

[maxtangli]

Suppose I have a Controller class to sort a datalist:

1. public enum SortType {t1,t2...t20}
2. public Class Controller {
3.     public void sort(SortType t);
4. }
5.  

then I have 20 buttons to call sort.
It would be convenient by using UIButton inspector to set callback function and param,
but when I select sort method, the appeared arg0 turn to type of Object.

So what would be the best practice to use UIButon for this case?

I know I could attach a script for each button, but it still need extra code:

1. class SortButton : Monobehavior {
2.     public SortType type;
3.     public Controller controller;
4.     void OnClick() {controller.sort(type)}
5. }
6.

You currently can't pass static values into the callback functions -- only dynamically linked properties. Ability to specify static parameters is a planned feature. I suggest going with the second approach for now.

Thanks for your answer.
Anticipate the coming of that feature
