Facebook open graph:内置object fitness.course

Question

我在努力(失败了很多！)使用Facebook iOS sdk。我想在不离开应用程序的情况下发布一个关于用户运行的故事。我正在尝试使用Facebook内置的对象"course“和内置的action来跑步。

我发现文档非常混乱，我的代码已经变得非常纠结，我确信这是尝试实现这个解决方案的最糟糕的方式。

我在下面的代码中得到的错误是：

2014-04-01 23:10:13.238 Fitness_App[2313:60b] Encountered an error posting to Open Graph: Error Domain=com.facebook.sdk Code=5 "The operation couldn’t be completed. (com.facebook.sdk error 5.)" UserInfo=0x16ba5190 {com.facebook.sdk:HTTPStatusCode=500, com.facebook.sdk:ParsedJSONResponseKey={
body =     {
    error =         {
        code = 1611072;
        message = "The action you're trying to publish is invalid because it does not specify any reference objects. At least one of the following properties must be specified: course.";
        type = Exception;
    };
};
code = 500;

}，com.facebook.sdk:ErrorSessionKey=}

我一直在为这个问题而苦苦挣扎，却找不到解决方案！

-(void) publishStory
    {
        // instantiate a Facebook Open Graph object
        NSMutableDictionary<FBOpenGraphObject> *object = [FBGraphObject openGraphObjectForPost];

        // specify that this Open Graph object will be posted to Facebook
        object.provisionedForPost = YES;

        // for og:title
        object[@"title"] = @"running title";

        // for og:type, this corresponds to the Namespace you've set for your app and the object type name
        object[@"type"] = @"fitness.course";

        // for og:description
        object[@"description"] = @"running description";



        // Post custom object
        [FBRequestConnection startForPostOpenGraphObject:object completionHandler:^(FBRequestConnection *connection, id result, NSError *error) {
            if(!error) {
                // get the object ID for the Open Graph object that is now stored in the Object API
                NSString *objectId = [result objectForKey:@"id"];
                NSLog([NSString stringWithFormat:@"object id: %@", objectId]);

                // Further code to post the OG story goes here
                // create an Open Graph action
                id<FBOpenGraphAction> action = (id<FBOpenGraphAction>)[FBGraphObject graphObject];
                [action setObject:objectId forKey:@"fitness.course"];

               [FBRequestConnection startForPostWithGraphPath:@"/me/fitness.runs" graphObject:action completionHandler:^(FBRequestConnection *connection, id result, NSError *error) {
                    if(!error) {
                        NSLog([NSString stringWithFormat:@"OG story posted, story id: %@", [result objectForKey:@"id"]]);
                    } else {
                        // An error occurred, we need to handle the error

                        NSLog(@"Encountered an error posting to Open Graph: %@", error.description);
                    }
                }];




            } else {
                // An error occurred
                NSLog(@"Error posting the Open Graph object to the Object API: %@", error);
            }
        }];
    }

Answer 1

有两个地方出了问题。

1. object[@"type"] = @"fitness.course";

type应等于@"namespace:object"。

• [action setObject:objectId forKey:@"fitness.course"];

关键字是您的对象名称。

再次检查您的代码，玩得开心^-^

Answer 2

尝试将这句话替换为"action setObject:objectId forKey:@"fitness.course";“

使用这一条

"action setObject:objectId forKey:@"course";“
