Question

嗨大家我已经创建了一个函数，在下面将项目保存到tweetData：[PFObject]数组

 func loadData() {

    //all current data to be displayed, adding data 1 by 1 remove whats there on reloading
    tweetData.removeAll()

    //query database for all tweets, very important that whats in the classname here, is the
    //same name as the class with Parse where these are being stored

    let findTweets:PFQuery = PFQuery(className: "Tweets")

    findTweets.findObjectsInBackgroundWithBlock { (objects:[PFObject]?, error: NSError?) -> Void in

        if error == nil {

            for object:PFObject in objects! {

                self.tweetData.append(object)

            }

            //--very important!!! dont forget to reload table data otherwise you will return no results
            self.tableView.reloadData()

        } else {

            print("nothing to load")

        }

    }

}

如何将这个显示在我的tableview中以显示数据？一直在努力，并得到各种错误。这是我的表视图cellForRowAtIndexPath

 func tableView(tableView: UITableView, cellForRowAtIndexPath  

 indexPath: NSIndexPath) -> UITableViewCell {

    //use your custom table view cell here which is defined in another class

    let cell:CellTableViewCellController = tableView.dequeueReusableCellWithIdentifier("cell", forIndexPath: indexPath) as! CellTableViewCellController


  //NEED TO LOAD MY DATA



    return cell

    //-----add load data function to viewDidAppear method


}

任何人都可以帮我这个吗？感谢

all sorted just used query.objectforkey


func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {

    //use your custom table view cell here which is defined in another class

    let cell:CellTableViewCellController = tableView.dequeueReusableCellWithIdentifier("Cell", forIndexPath: indexPath) as! CellTableViewCellController

    let query = tweetData[indexPath.row]

    cell.textLabel!.text = query.objectForKey("TweetContent") as? String

    return cell

    //-----add load data function to viewDidAppear method


}

从Parse将数据加载到TableView中
