iOS - Swift网络获取数据 ～(更新)

封装伊始
首先声明一个类继承于AFHTTPSessionManager

class SwiftHttpNetwork: AFHTTPSessionManager

 func setBaseUrl (baseURL:NSString?,timeOutInterval :Double ){
        SwiftHttpNetwork._baseURL = baseURL
        SwiftHttpNetwork.networkManager = SwiftHttpNetwork.init(baseURL:self.baseURL)
       SwiftHttpNetwork.networkManager?.requestSerializer = AFHTTPRequestSerializer()
       SwiftHttpNetwork.networkManager?.responseSerializer = AFJSONResponseSerializer.init()
        // 信任证书
        SwiftHttpNetwork.networkManager?.securityPolicy = AFSecurityPolicy.init(pinningMode: AFSSLPinningMode.none)
        SwiftHttpNetwork.networkManager?.securityPolicy.allowInvalidCertificates = true
        SwiftHttpNetwork.networkManager?.securityPolicy.validatesDomainName = false
        SwiftHttpNetwork.networkManager?.requestSerializer.timeoutInterval = timeOutInterval
        let contentTypes: Set = ["application/json", "text/json", "text/javascript","text/html", "application/x-javascript"]
        SwiftHttpNetwork.networkManager?.responseSerializer.acceptableContentTypes = contentTypes
    }

当你给的图片地址是一个URL时，你需要显示出来就需要去转换编码不然就不能显示的：如下所示

给定的图片地址是一个字符串类型的，所以需要转换为URL如下所示：

转换为URL后还需要转换为NSData类型数据，如下所示

let data = NSData(contentsOfURL: urlStr!)，后面带感叹号是用来拆解包的

之后就放入image中，如下所示：

let image = UIImage(data: data!)

整个代码如下所示：

        let urlStr = NSURL(string: "http://img.ivsky.com/img/tupian/pre/201509/13/tianzhukui.jpg")
        let data = NSData(contentsOfURL: urlStr!)
        let image = UIImage(data: data!)
        let imageView = UIImageView(image: image)
        imageView.frame = CGRectMake(0,0,SCR_PAGE.width,SCR_PAGE.height)
        self.view.addSubview(imageView)

---------------在这里面选择添加的数据-------------------

在News文件中添加数据

import UIKit

class News: NSObject {

    var title:String = " "
    var time = " "
    var scr = " "
    var pic = ""
    var content = ""
    var url = ""
    var weburl = ""


}

网络获取：进行数据转换

在文件中进行一些文件的获取

import UIKit

class URLService: NSObject {

    func getJokesData(pagenum:Int,pagesize:Int,sort:String, completion:@escaping (Any,Bool)->Void) ->Void  {

        //get方法
        var urlstr = "http://api.jisuapi.com/xiaohua/text?pagenum=\(pagenum)&pagesize=\(pagesize)&sort=\(sort)&appkey=de394933e1a3e2db"
        urlstr = urlstr.addingPercentEncoding(withAllowedCharacters: CharacterSet.urlFragmentAllowed)!
        let url = URL(string: urlstr)
        let req = URLRequest(url: url!, cachePolicy: .reloadIgnoringCacheData, timeoutInterval: 5.0)

        let task1 : URLSessionDataTask = URLSession.shared.dataTask(with: req) { (data, reponse, error) in
            if error != nil
            {
                completion("服务器错误",false)
                return
            }
            let jsonData = try?
                JSONSerialization.jsonObject(with: data!, options: JSONSerialization.ReadingOptions.allowFragments)
            if jsonData == nil
            {
                completion("解析错误",false)
                return
            }

            let status = (jsonData as! NSDictionary).value(forKey: "status") as! String
            let msg = (jsonData as! NSDictionary).value(forKey: "msg") as! String

            if Int(status)! != 0{
                completion(msg,false)
                return
            }
            let result = (jsonData as! NSDictionary).value(forKey: "result") as! NSDictionary

            let list = result.value(forKey: "list") as! NSArray

            var newArr:[News] = []



            for item in list
            {
                let dic = item as! NSDictionary

                let onenew = News()

                onenew.addtime = dic.value(forKey: "addtime")as! String
                onenew.content = dic.value(forKey: "content")as! String

                newArr.append(onenew)

            }
            completion(newArr, true)
        }



        task1.resume()

    }



}

最后在表格中进行展示

在viewcontroll中进行

import UIKit

class ViewController: UIViewController,UITableViewDataSource {

    var table:UITableView?
    var tableDataArr:[News]?





    func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        if let count = tableDataArr?.count {
            return count
        }
        return 0
    }

    func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        let ID = "cell"
        var cell = tableView.dequeueReusableCell(withIdentifier: ID)
        if cell == nil {
            cell = UITableViewCell.init(style: .subtitle, reuseIdentifier: ID)
        }
        let oneNew = self.tableDataArr![indexPath.row]
        cell?.textLabel?.numberOfLines = 0
        cell?.detailTextLabel?.numberOfLines = 0
        cell?.textLabel?.text = oneNew.content
        cell?.detailTextLabel?.text = oneNew.addtime


        return cell!
    }


    override func viewWillAppear(_ animated: Bool) {
        super.viewWillAppear(animated)
        UIApplication.shared.isNetworkActivityIndicatorVisible=true

        let urlService = URLService()
        urlService.getJokesData(pagenum: 1, pagesize: 10 , sort:" addtime") { (data, success) in
            DispatchQueue.main.async {
                UIApplication.shared.isNetworkActivityIndicatorVisible = false
            }

            if !success{

                DispatchQueue.main.async {
                    let alertVC = UIAlertController(title: nil, message: data as? String, preferredStyle: .alert)
                    let confinBth = UIAlertAction(title: "确定", style: .default, handler: nil)
                    alertVC . addAction(confinBth)
                    self.present(alertVC, animated: true, completion: nil)

                }
                return

            }

            self.tableDataArr = data as? [News]
            DispatchQueue.main.async {
                self.table?.reloadData()
            }

        }




    }


    override func viewDidLoad() {
        super.viewDidLoad()
        self.title = *****"
        self.table = UITableView.init(frame:self.view.frame , style: .plain)
        self.table?.dataSource = self
        self.view.addSubview(self.table!)

    }
