Really silly question here....does API v2 still require the app secret?

[ElizabethW]

Please forgive me if this is a really simple question, I've just started and I'm very confused. 

I'm migrating to API v2 using Objective C.  Unlike v1, v2 sample codes do not require the app secret anywhere. (just the app-key) Would you be able to provide me an example where the app-secret is used please?

API v2 exclusively uses OAuth 2, which doesn't require the app secret for client-side apps.

(The only exception is if you need to use any "app auth" endpoints, such as tokenFromOauth1, in which case you would specify both the app key and secret e.g., via DBTransportDefaultConfig. There's an example of that in this thread.)
