ios - 如何将 Json 数据推送到 UITableView 中的标签？

Question

我在一个自定义的 UITableview 单元格中有 3 个标签，我正在尝试传递我从带有 Alamofire 的 api 获得的 json 数据，但我很难理解如何将返回的 json 推送到 tableview 中。任何帮助将不胜感激。代码如下:

import UIKit
import Parse
import Alamofire

class LeagueTableController: UIViewController, UITableViewDataSource,     UITableViewDelegate {

override func viewDidLoad() {
    super.viewDidLoad()

    Alamofire.request(.GET, "https://api.import.io/store/connector/88c66c----9b01-6bd2bb--d/_query?input=webpage/url:----") .responseJSON { response in // 1
        print(response.request)  // original URL request
        print(response.response) // URL response
        print(response.data)     // server data
        print(response.result)   // result of response serialization

        if let JSON = response.result.value {
            print("JSON: \(JSON)")
        }
    }
}

func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    return 1
}

func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCellWithIdentifier("Cell", forIndexPath: indexPath)
    return cell
}


}

返回的json是这样的:

  {
connectorGuid = "88c66cb4-e64f-4316-9b01-6bd2bb2d762d";
connectorVersionGuid = "8aedfe43-948a-4559-b279-d3c3c28047a4";
cookies =     (
);
offset = 0;
outputProperties =     (
            {
        name = team;
        type = URL;
    },
            {
        name = played;
        type = DOUBLE;
    },
            {
        name = points;
        type = DOUBLE;
    }
);
pageUrl = "http://www.extratime.ie/leagues/2024/100/premier-division/";
results =     (
            {
        played = 9;
        "played/_source" = 9;
        points = 22;
        "points/_source" = 22;
        team = "http://www.extratime.ie/squads/17/";
        "team/_source" = "/squads/17/";
        "team/_text" = Dundalk;
    },
            {
        played = 9;
        "played/_source" = 9;
        points = 20;
        "points/_source" = 20;
        team = "http://www.extratime.ie/squads/7/";
        "team/_source" = "/squads/7/";
        "team/_text" = "Derry City";
    },
            {
        played = 9;
        "played/_source" = 9;
        points = 17;
        "points/_source" = 17;
        team = "http://www.extratime.ie/squads/100504/";
        "team/_source" = "/squads/100504/";
        "team/_text" = "Galway United FC";
    },
            {
        played = 9;
        "played/_source" = 9;
        points = 16;
        "points/_source" = 16;
        team = "http://www.extratime.ie/squads/29/";
        "team/_source" = "/squads/29/";
        "team/_text" = "St. Patrick's Ath";
    },
            {
        played = 8;
        "played/_source" = 8;
        points = 15;
        "points/_source" = 15;
        team = "http://www.extratime.ie/squads/30/";
        "team/_source" = "/squads/30/";

    },
            {
        played = 8;
        "played/_source" = 8;
        points = 15;
        "points/_source" = 15;
        team = "http://www.extratime.ie/squads/3/";
        "team/_source" = "/squads/3/";
        "team/_text" = "Shamrock Rovers";
    },
            {
        played = 9;
        "played/_source" = 9;
        points = 10;
        "points/_source" = 10;
        team = "http://www.extratime.ie/squads/13/";
        "team/_source" = "/squads/13/";
        "team/_text" = "Finn Harps";
    },
            {
        played = 9;
        "played/_source" = 9;
        points = 10;
        "points/_source" = 10;
        team = "http://www.extratime.ie/squads/2/";
        "team/_source" = "/squads/2/";
        "team/_text" = Bohemians;
    },
            {
        played = 9;
        "played/_source" = 9;
        points = 7;
        "points/_source" = 7;
        team = "http://www.extratime.ie/squads/8/";
        "team/_source" = "/squads/8/";
        "team/_text" = "Sligo Rovers";
    },
            {
        played = 9;
        "played/_source" = 9;
        points = 7;
        "points/_source" = 7;
        team = "http://www.extratime.ie/squads/6/";
        "team/_source" = "/squads/6/";
        "team/_text" = "Bray Wanderers";
    },
            {
        played = 9;
        "played/_source" = 9;
        points = 5;
        "points/_source" = 5;
        team = "http://www.extratime.ie/squads/109/";
        "team/_source" = "/squads/109/";
        "team/_text" = "Wexford Youths";
    },
            {
        played = 9;
        "played/_source" = 9;
        points = 5;
        "points/_source" = 5;
        team = "http://www.extratime.ie/squads/15/";
        "team/_source" = "/squads/15/";
        "team/_text" = "Longford Town";
    }
);

}我正在尝试将“played”、“points”和“team/_text”结果推送到每个标签。

由于问题非常广泛，并且没有具体说明这里的问题到底是什么，一般步骤是:

1) 将您的 json 映射到字典/nsdictionary。假设您发布的 JSON 片段是以下格式 [{}] 的 JSONArray block ，您需要做的就是:

var arrayOfDictionaries:NSArray = NSJSONSerialization.JSONObjectWithData(yourData, options: nil, error: nil) as! NSArray

其中 yourData 变量是从网络下载的转换为 NSData 格式的数据

2) 在自定义 tableViewCell 中创建这三个标签的导出

3) 对于每个单元格，在其中设置这些标签

func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath)

方法如下:

func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
  let cell:YourCustomCell = tableView.dequeueReusableCellWithIdentifier("Cell", forIndexPath: indexPath) as YourCustomCell
  cell.firstLabel.text = yourDictionary["played"]
  cell.secondLabel.text = yourDictionary["points"]
  cell.thirdLabel.text = yourDictionary["team"]
  return cell
}

4)我想您将需要更多的单元格，而不仅仅是一个单元格，然后在数组中存储许多字典并访问每个元素，如下所示:

cell.firstLabel.text = arrayOfDictionaries[indexPath.row]["played"]
