How can I get my button's UISprite to resize to the size of all its children?

[alexh0101]

I have a gameObject with UIButton and UISprite attached to it.
This gameObject has 2 children: one UI2DSprite and one UILabel.

Also, my label will resize freely.

How can I get my button's UISprite to automatically (and dynamically) get the size of whatever is inside of it?
Do I have to do a script for that?

Thanks in advance

EnvelopContent script can do that for you.
