What's the difference between UIControlStateHighlighted and UIControlStateSelected?

Question

I am trying to set a state for UIButton.

But i don't know the difference between the UIControlStateHighlighted and UIControlStateSelected.

Could anyone help me out?

Thanks and best regards.

They can mean whatever you want them to, but in general they mean the following:

Highlighted = The user is currently interacting with something that will change once they stop interacting (e.g. holding down a button)

Selected = The item is current the active item in a group (e.g. The selected item in a segmented control). This can only be achieved by setting it programmatically.
