将对象附加到Swift 3中的数组

尝试将我从Parse查询的对象推送到可以在UITableView中使用的数组时遇到了一些麻烦

这是我的密码

var locations = [AnyObject]()

override func viewDidLoad() {
    super.viewDidLoad()

    // Query the Locations class.
    let query = PFQuery(className:"Location")

    query.findObjectsInBackground {
        (objects: [PFObject]?, error: Error?) -> Void in
        if error == nil {
            if let objects = objects {
                for object in objects {
                    self.locations.append(object)
                }
                self.venueTable.reloadData()
            }
        } else {
            // Log details of the failure
            print("Error: (error!) (error!.userInfo)")
        }
    }

}

override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
    // Dispose of any resources that can be recreated.
}


func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {

    return locations.count
}

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {

    let locationCell = tableView.dequeueReusableCell(withIdentifier: "locationCell", for: indexPath)

    let location = locations[indexPath.row]

    locationCell.textLabel?.text = location

    return locationCell
}

在for循环之后，locations中充满了解析数据，但当将其推送到

locationCell

时，不确定如何访问它。为locations设置的类型是[AnyObject]，所以当您尝试设置labels text属性时，这将不起作用，因为它不是字符串

而是将其设置为[PFObject]，然后使用PFObject的函数objectForKey从检索到的对象中获取相关字符串值
