ios - Facebook 在 iOS 上不显示 map

Question

我尝试使用 facebook opengraph 显示 map 。所以我有一个 Facebook 故事

以及具有属性的对象类型

在我的代码中我创建对象

            var properties:NSDictionary = ["og:type": "myplanetnamespace:plan", "og:title": "Share on Facebook выа", "og:description": "In the frozen wastes to the north of Winterfell, sinister and supernatural forces are mustering.",
           "myplanetnamespace:geoplace:latitude": String(stringInterpolationSegment: self.plan.venue!.location.latitude),
           "myplanetnamespace:geoplace:longitude": String(stringInterpolationSegment: self.plan.venue!.location.longitude) ]
        var object:FBSDKShareOpenGraphObject = FBSDKShareOpenGraphObject(properties: properties as [NSObject : AnyObject])

和行动

    var action = FBSDKShareOpenGraphAction()
    action.actionType = "myplanetnamespace:create_plan"
     action.setObject(object, forKey: "plan")

以及内容

    var content:FBSDKShareOpenGraphContent = FBSDKShareOpenGraphContent()
    content.action = action
    content.previewPropertyName = "plan"

还有对话框

 var shareDialog = FBSDKShareDialog()
        shareDialog.fromViewController = self
        shareDialog.shareContent = content
        if ( shareDialog.canShow() == true ){
            shareDialog.show()
        }
        var error:NSError?
        if(!shareDialog.validateWithError(&error)){
            print ("error")
        }

我按照要求设置了位置属性，没有错误。我试图发表一篇文章，但它在没有任何 map 的情况下创建它 =((

geoplace 来自哪里？这不是 Facebook Open Graph 的一部分，是吗？你能做这样的事情吗:

[openGraphObject setObject:@{@"latitude": String(stringInterpolationSegment: self.plan.venue!.location.latitude), 
                         @"longitude": String(stringInterpolationSegment: self.plan.venue!.location.longitude)]}
             forKey:@"location"];
