Swift-网络、本地数据解析

概述数据地址 let _urlPath = NSBundle.mainBundle().pathForResource("news_list.json", ofType: nil) 1.对对象进行解析 //解析对象 func jsonUser(){ //Swift对象 let user = [ "user": "张三",

数据地址

let _urlPath = NSBundle.mainBundle().pathForResource("news_List.Json",ofType: nil)

1.对对象进行解析

//解析对象    func JsonUser(){        //Swift对象        let user = [            "user": "张三","@R_502_6889@": ["@R_502_6889@1": "大名","@R_502_6889@2": "小名"]        ]        //首先判断能不能转换        if (!NSJsONSerialization.isValIDJsONObject(user)) {            print("is not a valID Json object")            return        }        //将对象转换为NSData        let data : NSData! = try? NSJsONSerialization.dataWithJsONObject(user,options: [])        //把NSData对象转换回JsON对象        let Json : AnyObject! = try? NSJsONSerialization            .JsONObjectWithData(data,options:NSJsONReadingOptions.AllowFragments)        //验证JsON对象可用性        let users : AnyObject = Json.objectForKey("user")!        let @R_502_6889@1 : AnyObject = Json.objectForKey("@R_502_6889@")!.objectForKey("@R_502_6889@1")!        let @R_502_6889@2 : AnyObject = Json.objectForKey("@R_502_6889@")!.objectForKey("@R_502_6889@2")!        print("users: \(users),@R_502_6889@1: \(@R_502_6889@1),@R_502_6889@2 :\(@R_502_6889@2)")    }

2、对本地Json进行解析

func localData(){        let recvData2 = NSData.dataWithContentsOfMappedfile(_urlPath!) as! NSData        let tempArray  = try? NSJsONSerialization.JsONObjectWithData(recvData2,options: .MutableContainers)        //Json解析然后强转        if (tempArray?.count > 0){            for (var i = 0; i < tempArray?.count; i++){                let oneVIDeo = tempArray?[i] as! NSDictionary                //把里面转成字典                let ID = oneVIDeo.objectForKey("ID")                let type = oneVIDeo.objectForKey("type")                let Title = oneVIDeo.objectForKey("Title")                let summary = oneVIDeo.objectForKey("summary")                let image = oneVIDeo.objectForKey("image")                let model = ZWModel()                model.ID  = ID as! Int                model.type = type as! Int                model.Title = Title as? String                model.summary = summary as? String                model.image = image as? String                //把数据添加到模型数据                dataArray.addobject(model)            }            _tableVIEw?.reloadData()        }    }

3、使用NSURLConnection

func downloadData(){       //创建NSURL        //请求本地数据        let url = NSURL(fileURLWithPath: _urlPath!)        //请求网络数据         //let url = NSURL(string: _urlPath!)        //以url创建请求        let request = NSURLRequest(URL:url!)        //创建连接        _connection = NSURLConnection (request: request,delegate: self)    }//收到http相应头    func connection(connection: NSURLConnection,dIDReceiveResponse response: NSURLResponse){    }    //接收一段数据，这个函数会被调用多次    func connection(connection: NSURLConnection,dIDReceiveData data: NSData){       //把接收到的数据追加到_recvData后面        _recvData.appendData(data)    }    //数据接收完成    func connectionDIDFinishLoading(connection: NSURLConnection){        //接收完成函数，显示要解析的Json        let str = Nsstring(data: _recvData,enCoding: NSUTF8StringEnCoding)        //把二进制转化成字符串        print("s is \(str)")        //        let vIDeoArr = try? NSJsONSerialization.JsONObjectWithData(_recvData,options:.MutableContainers)        //Json解析然后强转        if (vIDeoArr?.count > 0){            for (var i = 0; i < vIDeoArr?.count; i++){              let oneVIDeo = vIDeoArr?[i] as! NSDictionary                //把里面转成字典                let ID = oneVIDeo.objectForKey("ID")                let type = oneVIDeo.objectForKey("type")                let Title = oneVIDeo.objectForKey("Title")                let summary = oneVIDeo.objectForKey("summary")                let image = oneVIDeo.objectForKey("image")                let model = ZWModel()                model.ID  = ID as! Int                model.type = type as! Int                model.Title = Title as? String                model.summary = summary as? String                model.image = image as? String                //把数据添加到模型数据                dataArray.addobject(model)            }        }        //重新刷新表格        _tableVIEw?.reloadData()    }

4、网络数据的请求和解析将（3）中的//请求网络数据 //let url = NSURL(string: _urlPath!)放开，地址改为网络地址
