How could Twitter know the source of TWRequest?

Question

I'm just curious. TWRequests use generic ACAccounts which are shared by all apps on iOS. Apps don't specify their own consumer_keys. So how could Twitter know which app a specific TWRequest come from?

Answer 1

Twitter can't tell which app a specific TWRequest comes from.

Accounts.framework embeds consumer_key and consumer_secret.

For Twitter, all requests just seem to be coming from iOS Twitter integration.

Answer 2

Query params adc=phone and application_id=your_iosapp_sig (i think) are added to each request url during the OAuth process. Twitter should be able to identify your app by the application_id

Once you build your TWRequest, you can see the url request by

NSLog(@"%@", request.signedURLRequest.URL.absoluteString);

This should reveal the above two params.
