Swift 从解析将数据加载到TableView
大家好,我在下面创建了一个函数,它将项目保存到tweetData:[PFObject]数组中Swift 从解析将数据加载到TableView,swift,parse-platform,tableview,Swift,Parse Platform,Tableview,大家好,我在下面创建了一个函数,它将项目保存到tweetData:[PFObject]数组中 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
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")
}
}
}
如何将其放入tableview以显示数据?我一直在挣扎,并且犯了各种各样的错误。这是我的表格视图cellforrowatinexpath
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
}
有人能帮我吗?谢谢
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
}
