使用Facebook iOS SDK获取应用访问令牌

Question

I am trying to get an Facebook App access token to get the Facebook page feed. If I send a request like this: [NSURLRequest requestWithURL:[NSURL URLWithString:@"https://graph.facebook.com/oauth/access_token?client_id=APP_ID&client_secret=APP_SECRET&grant_type=client_credentials"] I get a valid access token but I can't use this one in the FBSession because the accessToken property is read-only. So the question is: how do I obtain an Facebook App access token with FBSession?

Answer 1

If you successfully login then you can get accesstoken using

[[FBSession activeSession] accessToken];

Thanks.

Answer 2

Check out the Scrumptious sample, along with the other stuff Facebook has provided.

I did mine like:

[FBSession openActiveSessionWithReadPermissions:permissions allowLoginUI:YES completionHandler: ^(FBSession *session, FBSessionState state, NSError *error) { [self sessionStateChanged:session state:state error:error]; }];
