FBSDKGraphRequest use of undeclared identifier

Question

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?

Answer 1

Since version 4.X Facebook has split the SDK in 3 parts:

Per documentation :

The SDK is now composed of three frameworks, FBSDKCoreKit , FBSDKLoginKit , and FBSDKShareKit .

FBSDKCoreKit provides core SDK functionality such as Graph API Requests, access tokens, and App Insights.

FBSDKLoginKit provides functionality to log people in, and only requires FBSDKCoreKit .

FBSDKShareKit provides functionality to share, and only requires FBSDKCoreKit .

As for your question:

Requests - FBSDKGraphRequest and FBSDKGraphRequestConnection are in FBSDKCoreKit and provide helpers to access the Graph API

So basically you need to import FBSDKCoreKit in your file:

#import <FBSDKCoreKit/FBSDKCoreKit.h>

Answer 2

For login into Facebook using new SDK 4.1 You have to add the FBSDKLoginkit and FBSDKCoreKit Frameworks in your project.

Then import the below header files into your ViewController:

#import <FBSDKCoreKit/FBSDKCoreKit.h>
#import <FBSDKLoginKit/FBSDKLoginKit.h>
