Question

我需要将数组中的10个数组从JSON解析为swift并访问它。我可以通过REST API获取数据并在控制台上打印出来，但我不知道如何将其实际保存到进程中。

JSON数组结构：

[[lol_id, lol_time, lol_uid, lol_username, lol_type, lol_url, lol_title, lol_score, lol_comments, lol_badge], 
[lol_id, lol_time, lol_uid, lol_username, lol_type, lol_url, lol_title, lol_score, lol_comments, lol_badge], 
[lol_id, lol_time, lol_uid, lol_username, lol_type, lol_url, lol_title, lol_score, lol_comments, lol_badge], 
[lol_id, lol_time, lol_uid, lol_username, lol_type, lol_url, lol_title, lol_score, lol_comments, lol_badge], 
[lol_id, lol_time, lol_uid, lol_username, lol_type, lol_url, lol_title, lol_score, lol_comments, lol_badge], 
[lol_id, lol_time, lol_uid, lol_username, lol_type, lol_url, lol_title, lol_score, lol_comments, lol_badge], 
[lol_id, lol_time, lol_uid, lol_username, lol_type, lol_url, lol_title, lol_score, lol_comments, lol_badge], 
[lol_id, lol_time, lol_uid, lol_username, lol_type, lol_url, lol_title, lol_score, lol_comments, lol_badge], 
[lol_id, lol_time, lol_uid, lol_username, lol_type, lol_url, lol_title, lol_score, lol_comments, lol_badge], 
[lol_id, lol_time, lol_uid, lol_username, lol_type, lol_url, lol_title, lol_score, lol_comments, lol_badge]]

这些数组基本上返回整数和字符串。

如何以相同的样式（数组中的数组）保存它们并访问它们？

这是我到目前为止的代码：

@IBAction func buttonLoad(sender: AnyObject) {

    // Setting up the URL 
    let myUrl = NSURL(string: "http://hugelol.com/api/front.php");

    // Request 
    let request = NSMutableURLRequest(URL:myUrl!);
    request.HTTPMethod = "POST";

    let task = NSURLSession.sharedSession().dataTaskWithRequest(request) {
        data, response, error in

        if error != nil
        {
            println("error=\(error)")
            return
        }

        // Prints server response
        println("response = \(response)")

        // Prints the double array 
        let responseString = NSString(data: data, encoding: NSUTF8StringEncoding)
        println("responseString = \(responseString)")
    }
    task.resume()
}

我尝试了很多不同的方法，但在理解如何做到这一点时却遇到了很大的麻烦。我也尝试过swiftyJSON，但我仍然不知道如何将数据保存到swift数组中。我接近把头撞到墙上。谢谢你的阅读。

尝试使用NSJSONSerialization。它将解析JSON并返回一个NSObject树。

if let result: AnyObject = NSJSONSerialization.JSONObjectWithData(data, options: NSJSONReadingOptions(0), error: nil) {...}

这部分代码应该为您提供预期的结果

....

    // Setting up the URL
    let myUrl = NSURL(string: "http://hugelol.com/api/front.php");

    // Request
    let request = NSMutableURLRequest(URL:myUrl!);
    request.HTTPMethod = "POST";

    let task = NSURLSession.sharedSession().dataTaskWithRequest(request) {
        data, response, error in

        if error != nil
        {
            println("error=\(error)")
            return
        }

        if let jsonString = JSON(data: data).rawString() as String? {
            if let dataFromString = jsonString.dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: false) {
                let json = JSON(data: dataFromString)
// uncomment necessary access method                   
//                    for (index: String, subJson: JSON) in json {
//                        println("Arr = \(subJson)")
//                    }
// OR
//                    println(json[0][0])

            }
        }
    }

    task.resume()
