facebook-ios-sdk

问题 If I have a Facebook account set up in iOS6 but the user has switched it off, the SDK just gives me a FBSessionStateClosedLoginFailed status. From that, I can't tell if the user has switched us off in iOS (case 1) or doesn't have an account set up in iOS and declined permission from the FB app or web app (case 2). The error messages I need to present are quite different in the two cases. In the first case, we need to tell the user how to switch us back on, but those instructions would be

问题 I want to get /{user-id}/feed from another user (user B) rather than "me" (user A), but the query returns an empty list. I'm using the Graph API Explorer to make the queries, and I've got the Access Token with user_posts , user_status and read_stream permissions, but I can't get this information. In this thread is said that: Additionally the queried user needs to grant the app the read_stream permission. In this other thread they said: If the user is your app user authorized with read_stream

问题 Though I have imported FacebookSDK like: #import <FacebookSDK/FacebookSDK.h> , but it says: use of undeclared identifier 'FBSDKGraphRequest'. The code I wrote is simple: FBSDKGraphRequest *request = [[FBSDKGraphRequest alloc] initWithGraphPath:@"/{user-id}/albums" parameters:params HTTPMethod:@"GET"]; [request startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection, id result, NSError *error) { // Handle the result }]; Let me know what may I be missing? 回答1: Since version 4.X

问题 I follow all the steps in This Tutorial and/or Facebook SDK Documentation to install Facebook Login on my App, but when I run the code I get an error. although Facebook mention I can just use import (Swift) to include the framework, I try to do it the old fashion as well with Objective-C Bridge Header.

问题 I'm having trouble compiling the HelloFacebookSample app that comes with Facebook SDK 3.0. Firstly, I should say I'm using Xcode 4.0.2, iOS SDK 4.3 and OS X 10.6.8.

问题 I am trying to build an iOS application with a custom token caching mechanism.

I am able to cache the token onto my server. But the real problem happens when I run the app the next time after I logged into FB. This is the flow I follow to check if my app is logged into FB. 1) Hit a url on my server to get

问题 I have a website that uses Facebook authentication for logging in users. It uses the oAuth 2.0 server side flow for authentication and it all works fine. I am now developing an iPhone application for the same website and want to allow users to sign in to the website via the iPhone application using FB authentication.The Facebook iOS SDK provides mechanisms to do the authentication using the client side flow, where in my iPhone app gets the access token.
