解析JSON Swift TableView

唐·德雷珀

我想从此JSON URL（https://www.kimonolabs.com/api/7flcy3qm?apikey=gNq3hB1j0NtBdAvXJLEFx8JaqtDG8y6Y）中提取“事件”，“哈斯塔”和“位置” ，但我在努力解决它？谁能帮我？这是我的代码...我想用这3个填充表格视图。

override func viewDidLoad() {
    super.viewDidLoad()

    splitViewController!.preferredDisplayMode = UISplitViewControllerDisplayMode.AllVisible

    UINavigationBar.appearance().barTintColor = UIColor(red: 52.0/255.0, green: 170.0/255.0, blue: 220.0/255.0, alpha: 1.0)
    UINavigationBar.appearance().tintColor = UIColor.whiteColor()
    UINavigationBar.appearance().titleTextAttributes = [NSForegroundColorAttributeName : UIColor.whiteColor()]

    let url = NSURL(string:"https://www.kimonolabs.com/api/7flcy3qm?apikey=gNq3hB1j0NtBdAvXJLEFx8JaqtDG8y6Y")!
    let session = NSURLSession.sharedSession()

    let task = session.dataTaskWithURL(url) { (data, response, error) -> Void in
        if error != nil {
            print(error)
        } else {
            if let data = data {
                do {
                    let jsonResult = try NSJSONSerialization.JSONObjectWithData(data, options: NSJSONReadingOptions.MutableContainers) as? NSDictionary
                    if jsonResult!.count > 0 {
                        if let results = jsonResult!["results"] as? NSDictionary, collection2 = results["collection2"] as? NSArray {
                            for entry in collection2 {
                                if let dict = entry["Event"] as? NSDictionary {
                                    print(dict)
                                }

                                else if let array = entry as? NSArray {

                                } else {

                                }
                            }

                            if let items = jsonResult?["Date"] as? NSArray {
                                print(items)

                            }
                        }
                    }
                } catch {
                    print("In catch block")
                }
            }
        }
    }
    task.resume()
}

用Swift解析JSON真是太难了。您可以使用SwiftyJSON轻松地做到这一点。

使用您的JSON：

// Get content of json url
let jsonString = try NSString.init(contentsOfURL: url!, encoding: NSUTF8StringEncoding)

// Create JSON object from data
let json = JSON(data: jsonString.dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: false)!)

// Check if array for key "collection2" exists
if let collection2 = json["results"]["collection2"].array {
    // Create JSON array from it and loop for each object
    for (key, subJson):(String, JSON) in JSON(collection2) {
        // Check if dictionary for key "Event" exists
        if let event = subJson["Event"].dictionary {
             print(event)
        }

        // Check if string for key "Hasta" exists
        if let hasta = subJson["Hasta"].string {
             print(hasta)
        }

        // Check if string for key "Location" exists
        if let location = subJson["Location"].string {
             print(location)
        }
    }
}
