將圖像上傳到解析失敗

我無法保存捕獲的圖像，並使用Parse將其發送到我的mongodb。我不確定我的錯誤與什麼有關。我絕對有使用我的imagePickerController正確的圖像捕捉部分。將圖像上傳到解析失敗

這裏是我的代碼：

func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) { 
    if let image = info[UIImagePickerControllerOriginalImage] as? UIImage { 
     print("Did finish picking media. Image \(image)") 


     let imageData = UIImagePNGRepresentation(image) 
     let imageFile = PFFile(name:"image.png", data:imageData!) 



     let pohto_object = PFObject(className: "UserPhoto") 
     pohto_object["imageName"] = "My trip to Hawaii!" 
     pohto_object["imageFile"] = imageFile 

     pohto_object.saveInBackground() { (success, error) -> Void in 
      if error == nil { 
       print("Saved in server") 
      } else { 
       print("did not save because: \(error!)") 
      } 
     } 
     print ("the object is \(pohto_object)") 




    } else { 
     print("Did finish picking media. Image is nil") 
    } 
    dismiss(animated: true) 
}

這是我在控制檯輸出：

Did finish picking media. Image <UIImage: 0x17468ac30> size {3024, 4032} orientation 3 scale 1.000000

注意UIImagePNGRepresentation將導致未壓縮的數據（太多的數據上傳），它也將放棄您的圖像方向。我推薦使用UIImageJPEGRepresentation –

這解決了我的問題！謝謝！ –

所以我的問題是由UIImagePNGRepresentation改爲UIImageJPEGRepresentation解決了利奧指示
