Arcgis selectFeatures withQuery

Question

我想使用折线从SketchEditor.polyline创建的Featurelayer中查询要素。但是，我总是得到结果，好像我按多边形查询结果。代码如下：

 func featureSpaceSelection(mapGeometry:AGSGeometry){

    let queryParams = AGSQueryParameters()
    queryParams.geometry = mapGeometry


    //选中查询features
    self.featureLayer.selectFeatures(withQuery: queryParams, mode: AGSSelectionMode.new) { (queryResult:AGSFeatureQueryResult?, error:Error?) -> Void in

        print("geometry Type",queryResult?.geometryType.rawValue)
        if let error = error {
            print(error)
            self.selectedFeatures.removeAll(keepingCapacity: false) //清空查询选项
        }
        else if let result = queryResult {

            let features = result.featureEnumerator().allObjects
            self.featureLayer.select(features)
            self.selectedFeatures = features

            //发送通知
            let NotifyChatSelectFeatures = NSNotification.Name(rawValue:"notifyChatSelectFeatures")
            NotificationCenter.default.post(name: NotifyChatSelectFeatures, object: features)

            //获取feature信息
            for element in features{

                //添加覆盖物
                self.graphicsOverlay.graphics.add(self.polygonStyle(geometry: element.geometry!))
            }
        }
    }
}

mapGeometry是sketchEditor.geometry（），它是通过self.sketch.start（with：nil，creationMode：.polyline）创建的。
