I am trying to get a popup appear the first time an app is started. Just to give you an idea check the new version of foursquare. A small popup (like a comic) appear explaining where the checkin button is located. Then if you tap anywhere it goes away. I googled for the last hour but I have not found anything at all and I have no idea on how to do it.
Anyone can point me in the right direction?
Thanks in advance, Umberto
