如何使用iOS SDK發布包含地圖的Facebook操作？

Question

我想發布一個開放圖健身：在Facebook上運行動作，並希望它與路徑地圖一起呈現。 該路徑由下面的路徑坐標定義。 我該怎么做呢？ 下面的方法將發布操作，我可以在Facebook的“活動日志”中和時間軸中看到該操作的文本。 但是，當我將鼠標懸停在已發布操作的任何元素上時，我看不到地圖。 我究竟做錯了什么？

- (void) fbPost:(NSString *)txt toList:(NSString *)listId { // post

                [FBSession setActiveSession:[FacebookManager instance].facebook.session];



                NSMutableDictionary<FBGraphObject> *action = [FBGraphObject graphObject];
                action[@"course"] = @"http://samples.ogp.me/48586838281818";
                action[@"privacy"] = privacyStr;


                NSMutableArray *coords = [NSMutableArray arrayWithCapacity:59];
                for (int i = 0; i < 59; i++)
                {
                    NSMutableDictionary *coord = [[NSMutableDictionary alloc] initWithCapacity:3];

            #define TIMESTAMP @"fitness:metrics:timestamp"
            #define LATITUDE @"fitness:metrics:location:latitude"
            #define LONGITUDE @"fitness:metrics:location:longitude"
                    [coord setValue:[NSString stringWithFormat:@"2013-04-01T12:%2d:00+0000", i] forKey:TIMESTAMP];
                    [coord setValue:[NSString stringWithFormat:@"%f", 37.442564 + i * 0.00001] forKey:LATITUDE];
                    [coord setValue:[NSString stringWithFormat:@"%f", -122.164879 + i * 0.000001] forKey:LONGITUDE];
                    [coords addObject:coord];
                    NSLog(@"coord=%@ i=%d", coord, i);

                }

                action[@"path"] = [coords JSONString];
                action[@"message"] = txt;


                [FBRequestConnection startForPostWithGraphPath:@"me/fitness.runs"
                                                   graphObject:action
                                             completionHandler:^(FBRequestConnection *connection,
                                                                 id result,
                                                                 NSError *error) {
                                                 [UIApplication sharedApplication].networkActivityIndicatorVisible = NO;

                                                 if (!error) // it's a post, save id
                                                 {
                                                 }
                                                 else
                                                 {
                                                 }




                                             }];

            }
