In app user guide solution
I was wondering on what solutions / API's that might be out there for creating 'in application' guides for users?

For instance if the user opens the app for the first time I might have an overlay with some information or an animation (arrow) to a button saying submit and why etc.

My question is what are the ios standards for doing these sort of things, and are there any 3rd party API's for such things.
