What I want is, I have 6 UIButtons, if I touch one of them, its tween color start ping pong and shows its now selected.
And if I touch another button, previous button's tween color effect should be turn off and new touched button's tween color effect should start.
So I added UIEventTrigger and set tween color sprite to 'On Select'.
But I don't know how to stop this when click another button.
