转换PFGeoPoint为字符串错误

Question

我绑在解析服务器保存PFGeoPoint用下面的代码：

var coordinates = PFGeoPoint (latitude: (newCoordinate2.latitude), longitude:(newCoordinate2.longitude)) 

     var aboutSpot = PFObject(className: "spotdetail") 

     aboutSpot["name"] = "name" 
     aboutSpot [PFGeoPoint] = coordinates 
     aboutSpot.saveInBackgroundWithBlock { (succes, error) -> Void in 
      print("separate name and geopoint have been saved") 
     } 

，我得到以下信息：

swift cannot convert value of type `(PFGeoPoint).type (aka 'PFGeoPoint.type`) to expected argument type 'String' 

我可以改变，因此Xcode停止思考我想保存一个字符串？

Answer 1

我想通了，所以我在解析服务器手动添加一列，然后改变了这样的代码，它现在的作品，感谢帮助了

var coordinates = PFGeoPoint (latitude: (newCoordinate2.latitude), longitude:(newCoordinate2.longitude)) 

var aboutSpot = PFObject(className: "spotdetail") 

aboutSpot["name"] = "replaceNow" 
aboutSpot ["PFGeoPoint"] = coordinates 
aboutSpot.saveInBackgroundWithBlock { (succes, error) -> Void in 
    print("separate name and geopoint have been saved") 
} 

Answer 2

尝试先将经度和纬度作为double，然后使用distanceInKilometersTo或distanceInMilesTo。

希望这会有所帮助。
