使用Xcode 8和Swift 3在解析中更新用户位置

Question

I am running Parse Server and trying to log a user in and then update their location . Right now I am just manually creating a PFGeoPoint and then trying to add it to the key " location " which I have already added on Parse Server as a PFGeoPoint. When I run the following code I receive an error.

 let currentUser = PFUser.logInWithUsername(inBackground: "test", password: "test")
 let point = PFGeoPoint(latitude: 25.000, longitude: 25.000)
 currentUser.setValue(point, forKey:"location")

The error is as follows:

'NSUnknownKeyException', reason: '[<BFTask 0x60000067da00> setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key location.'

How can I resolve this error? Any help would be much appreciated! I am using Xcode 8 and Swift 3.

Answer 1

PFGeoPoint.geoPointForCurrentLocationInBackground { 
    (geoPoint: PFGeoPoint?, error: NSError?) -> Void in 
          if error == nil { 
               print("got location successfully") 
               PFUser.currentUser()!.setValue(geoPoint, forKey:"location") PFUser.currentUser()!.saveInBackground() 
          } else { 
               print(error) 
          } 
 }

here is method that is use for find the user current location and pass that data to your server with your PFGeoPoint that task is perform in Background. here i also mention that if your location changes or get it so in server PFUser update their location with new one . hope you are little clear about this.

thank you.
