Assign/access a button's "Pressed Sprite" at runtime

I was curious if you could do this in code. I have prefabs from which I instantiate button objects at runtime, these prefabs' Button component has a Sprite Swap transition. I'm able to change the main image of the instances, but can't find a way to change the pressed image.

The purpose is to have a small number of prefabs with different properties which I can then select and combine in the instances, for example the Text children of prefab A combined with the sprites of prefab B.

 

You want to look at the btn.spriteState.pressedSprit. The spriteState also contains the highlighSprite and disabledSprite.

 

Thank you, it worked.

 

how do you use this pls explain im new thanks!
