SwiftJson 实现网络数据的加载与解析并实现简单的轮播

最终效果图:

原始Json格式为(如下图所示):

转换之后的图片数组中的数据为:

1,整体目录结构

2,创建控制器,并在当前控制器中编写轮播图层 

//当前控制器属性
    @IBOutlet weak var homeTableView: UITableView!
    @IBOutlet weak var cycleScrollViewNew: WRCycleScrollView!
    
    //下拉刷新控制器
    private var refreshControl = UIRefreshControl()

    override func viewDidLoad() {
        super.viewDidLoad()

        view.backgroundColor = UIColor.white
        
        //首页初始化
        homeViewControllerInitSetting()
        setupHomeObtainDataFromNetWork()
       
    }
    
    //home控制器初始化方法
   fileprivate func homeViewControllerInitSetting(){

        //设置Navigation
        navigationController?.navigationBar.barStyle = UIBarStyle.blackTranslucent
        UIApplication.shared.statusBarStyle = UIStatusBarStyle.lightContent
        navigationController?.navigationBar.tintColor = UIColor.white
        
        //设置刷新视图
        refreshControl.addTarget(self, action: #selector(refreshViewMethod), for: UIControlEvents.valueChanged)
        refreshControl.attributedTitle = NSAttributedString(string: "下拉刷新")
        homeTableView.addSubview(refreshControl)
    }
    
    //轮播方法
   fileprivate func cycleScrollViewMethod(){
        
        
        print("=====PIC:\(self.cyclePicArray)");
        
        cycleScrollViewNew = WRCycleScrollView(frame: cycleframe , type: .SERVER, imgs: self.cyclePicArray, descs: self.titleLabelArray)

        cycleScrollViewNew?.delegate = self
        homeTableView.tableHeaderView = cycleScrollViewNew
    }
    
    //下拉刷新方法
    func refreshViewMethod(){
        
        print("下拉刷新")
        setupHomeObtainDataFromNetWork()
        
        //延时
        DispatchQueue.main.asyncAfter(deadline: .now() + 2) {

            self.refreshControl.endRefreshing()
        }
        
    }
}

//轮播代理方法的实现
extension AKHomeController : WRCycleScrollViewDelegate {

    //轮播点击方法
    func cycleScrollViewDidSelect(at index: Int, cycleScrollView: WRCycleScrollView) {
        
        print("你点击了第\(index + 1)张图片")
        
        let cycleDetail = AKHomeCycleDetail()
        
        navigationController?.pushViewController(cycleDetail, animated: true)
    }
}

//当前控制器出现与消失的方法
extension AKHomeController{
    
    override func viewDidAppear(_ animated: Bool) {
        
        tabBarController?.tabBar.isHidden = false
    }
}

3.调用已经封装的网络加载方法,实现数据的解析

//加载网络数据
extension AKHomeController{
    
    func setupHomeObtainDataFromNetWork(){
        
        let netPack = AKNetPackegeAFN.shareHttpManager()
        let url = "http://192.168.199.244/iOS/Swift/cycleScroll.html"
       
       //封装的网络加载方法
       netPack?.netWorkType(AKNetWorkGET, signature: nil, api: url, parameters: nil, requestTimes: 10, success: { (Json) in
        
        //将网络加载的NSAarray,NSDictionary等类型转换为Data类型
        let datJ = self.jsonToData(jsonDic: Json as! NSArray)
        let model = JSON(data: datJ!)
        
        //数据数组
        var titleArrayM = Array<String>()
        var detailIDM = Array<String>()
        var cyclePicM = Array<String>()
        
        for  i in 0 ..< model.count {
            
            //将要添加的数据转换为String类型并拼接到String类型的Array里
            titleArrayM.append(String(describing: model[i]["cycleTitle"]))
            detailIDM.append(String(describing: model[i]["cycleDetailID"]))
            cyclePicM.append(String(describing: model[i]["cyclePic"]))
        }

        self.titleLabelArray = titleArrayM
        self.detailIDArray = detailIDM
        self.cyclePicArray = cyclePicM
        
        //轮播
        self.cycleScrollViewMethod()
        self.homeTableView.reloadData()
        
       }, fail: { (Error) in
        
        print("HomeCycleError:\(String(describing: Error))")
       })
    }
    
    
    //将请求到的数组转换为Data
    fileprivate func jsonToData(jsonDic:NSArray) ->Data?{
    
    if(!JSONSerialization.isValidJSONObject(jsonDic)) {
    
    print("is not a valid json object")
    
    return nil
    
    }
    
    //利用自带的json库转换成Data
    
    //如果设置options为JSONSerialization.WritingOptions.prettyPrinted，则打印格式更好阅读
    
    let data = try? JSONSerialization.data(withJSONObject: jsonDic, options: [])
    
    //Data转换成String打印输出
    
    let str = String(data:data!, encoding: String.Encoding.utf8)
    
    //输出json字符串
    
    print("Json Str:\(str!)")
    
    return data
    
    }

}
