ios - 使用 swift 发起 HTTP GET 请求

Question

我正在尝试快速获取请求并填充我的 TableView 。截至目前，我已经准备好需要填充到我的 table 中的 json 数据，看起来像

因为我刚刚开始学习swift，所以我发现提出请求有点困惑。这是我的 RestaurantTableViewController.swift

override func viewDidLoad() {
        super.viewDidLoad()

        var url: String = "http://localhost:8888/restaurant/registeruser.php"

        var request: NSMutableURLRequest = NSMutableURLRequest()

        request.URL = NSURL(string: url)

        request.HTTPMethod = "GET"

        request.timeoutInterval = 60


        NSURLConnection.sendAsynchronousRequest(request, queue: NSOperationQueue()) { (respose:NSURLResponse!, data:NSData!, error:NSError!) -> Void in

            var error: AutoreleasingUnsafeMutablePointer<NSError?> = nil

            let jsonResult: NSDictionary! = NSJSONSerialization.JSONObjectWithData(data, options: NSJSONReadingOptions.MutableContainers, error: error) as? NSDictionary

            if (jsonResult != nil){
                //success
                println(jsonResult)

                let dataArray = jsonResult["name"] as! NSArray;

                for item in dataArray {  //loop through data items

                    let obj = item as! NSDictionary

                    for(key, value) in obj{

                        let allnames = obj["name"] as! NSString;
                    }
                }
            }
        }

    }

这就是我到目前为止所做的一切，在此之后，我应该如何让我的表填充餐厅名称，类型，和 位置。任何彻底的帮助将不胜感激。

我建议使用 https://github.com/daltoniam/JSONJoy-Swift它会让事情变得更容易和更清洁。

至于通话

var DISPATCH_TIME_FOREVER: UInt64 { get }

var url: String = "http://localhost:8888/restaurant/registeruser.php"
let sem = dispatch_semaphore_create(0)

var responseData = NSData()
NSURLSession.sharedSession().dataTaskWithURL(url, completionHandler: {(data, response, error) -> Void in
        responseData = data
        dispatch_semaphore_signal(sem)
    }).resume()
    dispatch_semaphore_wait(sem, DISPATCH_TIME_FOREVER)
    let jsonResult: NSDictionary! = NSJSONSerialization.JSONObjectWithData(responseData, options: NSJSONReadingOptions.MutableContainers, error: error) as? NSDictionary

        if (jsonResult != nil){
            //success
            println(jsonResult)

            let dataArray = jsonResult["name"] as! NSArray;

            for item in dataArray {  //loop through data items

                let obj = item as! NSDictionary

                for(key, value) in obj{

                    let allnames = obj["name"] as! NSString;
                }
            }
        }
