ios - 如何发送坐标进行解析并将其保存为 parse PFGeopoint

Question

如何将坐标发送到 CLLocation 获取的 Parse 并将其保存为 PFGeoPoint 的纬度和经度？

我能够从 CLLocation 获取坐标，我想将其发送到 Parse。在 Parse 中，我有一个名为“coordinates”的列，类型为 PFGeoPoint，它有两个字段。现在我想将从 CLLocation 获得的坐标保存到 Parse Column 坐标。谁能帮我解决这个问题？我是 iOS 和 Parse 的新手。

Answer 1

两步：

1. 将 CLLocation 转换为 PFGeoPoint

   //SWIFT
   let point = PFGeoPoint(location: currentLoc)
   
   //Obj-c
   [PFGeoPoint *point = PFGeoPoint geoPointWithLocation:(PF_NULLABLE CLLocation *)location];
   

2. 现在保存它。

   //SWIFT
   object["coordinates"] = point
   object.saveInBackgroundWithBlock {
     (success: Bool, error: NSError?) -> Void in
     if (success) {
               // The object has been saved.
     } else {
               // There was a problem, check error.description
     }
   }
   
   //Obj-c
   object["coordinates"] = point;
   [object saveInBackgroundWithBlock:^(BOOL succeeded, NSError *error) {
     if (succeeded) {
       // The object has been saved.
     } else {
       // There was a problem, check error.description
     }
   }];
