I don't see a reason why it can not be used. The APIs are standard RPC calls which you would make with appropriate OAuth credentials. The support document has a php sample code. You can follow the same approach for iOS too. Thanks
QUOTE (Johnny @ 18 Jan 2012 10:51 PM) I looked over the Objective-C Yahoo Social SDK and it supports OAuth and contains Yahoo Social API request.
Can this SDK be used for Yahoo! Mail API too?
If not, are there any examples showing how to use Yahoo! Mail API on iPhone/iOS?
I'm writing an applications that displays "unread" mail messages to my users.
