在 Swift 中打开图表故事获得全白屏幕

Question

我正在尝试 post 将图表故事发送到 Facebook。我有一个应用程序，我的用户可以在其中跟踪不同轨道上的自行车骑行情况。然而，这段代码只是打开一个纯白色的 safari 页面，没有其他任何事情发生。

谁能看出我做错了什么？

   var properties : [NSObject : AnyObject] = [
                    "og:type": "fitness.course",
                    "og:title": "My title",
                    "og:description": "The ride you took",
                    "fitness:duration:value": self.rideModel.totalSeconds,
                    "fitness:duration:units": "s",
                    "fitness:distance:value": self.rideModel.totalDistance,
                    "fitness:distance:units": "m",
                ];

                var i = 0;

                let formatter = NSDateFormatter()
                formatter.dateFormat = "yyyy'-'MM'-'dd'T'HH':'mm'"




                for point in trackPointItems{


                    properties["fitness:metrics[\(i)]:location:latitude"] = point.latitude
                    properties["fitness:metrics[\(i)]:location:longitude"] = point.longitude
                    properties["fitness:metrics[\(i)]:location:altitude"] = point.altitude
                    properties["fitness:metrics[\(i)]:timestamp"] = formatter.stringFromDate(point.timeStamp)


                    i += 1;

                }

                let graphObject = FBSDKShareOpenGraphObject(properties: properties)

                let action = FBSDKShareOpenGraphAction()
                action.actionType = "fitness.course"
                action.setObject(graphObject, forKey: "fitness.course")

                let content = FBSDKShareOpenGraphContent()

                content.action = action
                content.previewPropertyName = "fitness.course"


                FBSDKShareDialog.showFromViewController(self, withContent: content, delegate: self)

Answer 1

我发现我的积分太多了。我减少了数组中的点数 - 只取了第二个点。然后就成功了。
