如何从facebook ios sdk 3.1获取访问令牌？

Question

how to get the access token from facebook ios sdk 3.1?

I'm already getting the facebook login. Once the login is completed, the app comes to foreground. Although I could not yet figure out how to get the access token from this.

I get null from [[FBSession activeSession] accessToken]; command.

Any ideas?

Answer 1

accessToken is deprecated so you should use this ...

[[FBSession activeSession] accessTokenData];

This will help you......

Answer 2

FBSession.accessToken , an NSString* , is deprecated. FB documentation suggests using (FBAccessTokenData*) accessTokenData instead. FBAccessTokenData has a field, (NSString*) accessToken , so the solution is to substitute

[FBSession activeSession].accessToken

with

[FBSession activeSession].accessTokenData.accessToken

EDIT: We're up to SDK 3.8 at the time of this writing.
