Swift 如何从解析中检索地质点并将其存储在tableView中？

您好，我有一个应用程序，它将带有名称的地理点存储在解析服务器中，我可以从该服务器将数据检索到控制台，但我无法用它们填充tableView。我怎么能这样做？谢谢

以下是我用来存储数据的代码：

let geoPoint = PFObject(className: "location")

geoPoint["location"] = activePlace
geoPoint["spot"] = places
geoPoint.saveInBackgroundWithBlock { (succes, error) -> Void in
    print("place has been saved")
}

下面是我用来检索它的代码：

let query = PFQuery(className: "location")
query.findObjectsInBackgroundWithBlock { (object, error) in
   
    
    if error != nil {
        
        print(error)
        
    }else {
        
        print(object)
        self.tableView.reloadData()
        
    }
}

以下是我确定tableView的方式：

override func numberOfSectionsInTableView(tableView: UITableView) -> Int {
    
    return 1
    
}

override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    
    return places.count
    
    
}

override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
    
    let cell = tableView.dequeueReusableCellWithIdentifier("Cell", forIndexPath: indexPath) as UITableViewCell
    
    cell.textLabel?.text = places[indexPath.row]["name"]
  
    
    return cell
    
    
    
}

这就是“地点”的确定方式：

var places = [Dictionary<String,String>()]

var places=[Dictionary（）]

下面是我在解析服务器上的内容：

谢谢你的帮助
