在KDNewsListApi类，并且实现下面的方法
1funcgetNewsData(){23varurl:NSURL=NSURL(string:self.url)45varrequest:NSURLRequest=NSURLRequest(URL:url)67varconnection=NSURLConnection(request:request,delegate:delegate,startImmediately:false)//初始化一个connection89println("NewsListUrlis:\(self.url)")1011connection.start();//通过start方法启动连接1213}
在KDNewsListController类,实现以下接口函数
funcconnection(didReceiveResponse:NSURLConnection!,didReceiveResponseresponse:NSURLResponse!){//Recievedanewrequest,clearoutthedataobjectself.data=NSMutableData()}funcconnection(connection:NSURLConnection!,didReceiveDatadata:NSData!){//Appendtherecievedchunkofdatatoourdataobjectself.data.appendData(data)}funcconnectionDidFinishLoading(connection:NSURLConnection!){varerr:NSErrorvarjsonResult:NSDictionary=NSJSONSerialization.JSONObjectWithData(self.data,options:NSJSONReadingOptions.MutableContainers,error:nil)asNSDictionaryprint("NewsListJsonData:\(jsonResult)")}
协议2
在KDNewsDetailApi类，并且实现下面的方法
1funcgetNewsData(){23varurl:NSURL=NSURL(string:self.url)45varrequest:NSURLRequest=NSURLRequest(URL:url)67varconnection=NSURLConnection(request:request,delegate:delegate,startImmediately:false)89println("NewsDetailUrlis:\(self.url)")1011connection.start()1213}
初始化一个NSURLConnection类，并且执行start方法
在KDNewsDetailController类,实现以下接口函数
1funcconnection(didReceiveResponse:NSURLConnection!,didReceiveResponseresponse:NSURLResponse!){23//Recievedanewrequest,clearoutthedataobject45self.data=NSMutableData()67}89funcconnection(connection:NSURLConnection!,didReceiveDatadata:NSData!){1011//Appendtherecievedchunkofdatatoourdataobject1213self.data.appendData(data)14}151617funcconnectionDidFinishLoading(connection:NSURLConnection!){1819varerr:NSError2021varjsonResult:NSDictionary=NSJSONSerialization.JSONObjectWithData(self.data,2223options:NSJSONReadingOptions.MutableContainers,2425error:nil)asNSDictionary2627print("NewsDetailJsonData:\(jsonResult)")2829}运行的结果如下:

两个协议测试成功，完成接口部分，下一章节会进行UI部分的开发。
另外写代码的时候swift遇到一点小问题，网上下载了一个项目，后来xcode编辑器里面的语法高亮都变成了灰色,很怪异，估计是命名里面有swift关键字的原因吧（有待研究），把项目关了重启xcode就ok了
