ios - FBSDKGraphRequest 使用未声明的标识符

Question

虽然我已经导入了 FacebookSDK，例如:#import <FacebookSDK/FacebookSDK.h> ，但它说:使用未声明的标识符“FBSDKGraphRequest”。

我写的代码很简单:

FBSDKGraphRequest *request = [[FBSDKGraphRequest alloc]
                                      initWithGraphPath:@"/{user-id}/albums"
                                      parameters:params
                                      HTTPMethod:@"GET"];
[request startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection,
                                              id result,
                                              NSError *error) {
            // Handle the result
        }];

让我知道我可能缺少什么？

自版本 4.X 以来，Facebook 将 SDK 分为 3 部分:

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.

至于你的问题:

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

所以基本上你需要在文件中导入FBSDKCoreKit:

#import <FBSDKCoreKit/FBSDKCoreKit.h>
