var accountId = String()
var dataRows = [NSDictionary]()
var grandChilds = [NSDictionary]()
var dataOfGrandChilds = NSMutableDictionary()
override func viewDidLoad() {
    super.viewDidLoad()
    print("loaded hie \(accountId)")
    let request = SFRestAPI.sharedInstance().requestForQuery("SELECT Name,Id FROM Account where parentid='\(self.accountId)'");
    //SFRestAPI.sharedInstance().send(request, delegate: self);
    SFRestAPI.sharedInstance().sendRESTRequest(request, failBlock: {error in print(error)}, completeBlock: { responce in print(responce)
        self.dataRows = responce["records"] as! [NSDictionary]
        var counter = 0;
        for i in self.dataRows
        {
            let requestForGrandChilds = SFRestAPI.sharedInstance().requestForQuery("select Name,Id from Account where parentid='\(i["Id"]!)'")
            SFRestAPI.sharedInstance().sendRESTRequest(requestForGrandChilds,
            failBlock:
            {
                error in print(error)
                print("error block")
            },
            completeBlock:
            {
                responceChild in
                self.grandChilds = responceChild["records"] as! [NSDictionary]
                self.dataOfGrandChilds["\(counter)"] = self.grandChilds
                print(self.dataOfGrandChilds)
                counter += 1
                print("control still in inner competion block")
                dispatch_async(dispatch_get_main_queue(),
                    { () -> Void in
                        print("Control came to main queue")
                        self.tableView.reloadData()
                })
            })   
        }

    })

}
override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    // #warning Incomplete implementation, return the number of rows
    if(dataOfGrandChilds.count > 0 ){
        return dataOfGrandChilds.count
    }
    return 1
}

override func tableView(tableView: UITableView, titleForHeaderInSection section: Int) -> String? {
    return dataRows[section]["Name"] as? String
}
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCellWithIdentifier("toViewChilds", forIndexPath: indexPath)
    print(indexPath.section)
    print(dataOfGrandChilds["\(indexPath.section)"])
    if let tempData = dataOfGrandChilds["\(indexPath.section)"]
    {
        cell.textLabel?.text = tempData[indexPath.row]["Name"] as? String
    }
    return cell
}

在第一个请求中,我正在尝试获取Id的直接子帐户。在第一个请求的完成块中,我正在尝试获取大孩子帐户。     dataRows包含节标题的数据(这是直接的子名称)。     dataOfGrandChilds是一个字典,它将段号作为键,相应的grandChilds数组作为其值。

在重新加载我的tableView时,我只能显示第1个子节点而不显示第二节子节点。请帮助找到解决方案。

我得到的错误是

1 个答案:

答案 0 :(得分:1)

foreach($_FILES as $file) {
        if (move_uploaded_file($file['tmp_name'], $uploaddir.basename($file['name']))) {
            $files[] = $uploaddir.basename($file['name']);
        } else {
            $error = true;
        }
    }

完成的更改是:

  1. numberOfRowsInSection():       返回正确的行数
  2. 的cellForRowAtIndexPath():       tempData.count!= 0因为我们需要避免NSRangeException
