I am having trouble working out how to open and close things on tap. I will be using this function throughout the story app I am creating.

On certain pages, a "?" button will signify that a quiz is there. Tapping the button will open the quiz. That part is fine. But I want the button to change to an "x" and when tapped will close the quiz.

I will have the same for info buttons. a "book" icon will be tapped and information will appear. The icon will change to an "x" and when tapped the information will close.

Is there a step-by-step tutorial to do this? I have searched but cannot find anything.

Hi,

One way you can accomplish that is by using 2 buttons overlapped. On top the '?' button and bellow the 'X' button. Then you can attach for example the following interactions

'?' button:
- Tap or Touch Up
Hide (self)
Show Quiz

'X' button:
- Tap or Touch Up
Show '?' button
Hide Quizz
