轉換PFGeoPoint爲字符串錯誤

Question

我綁在解析服務器保存PFGeoPoint用下面的代碼：

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' 

我可以改變，因此Xcode停止思考我想保存一個字符串？

Answer 1

我想通了，所以我在解析服務器手動添加一列，然後改變了這樣的代碼，它現在的作品，感謝幫助了

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

嘗試先將經度和緯度作爲double，然後使用distanceInKilometersTo或distanceInMilesTo。

希望這會有所幫助。
