iOS网络开发-AFNetworking请求asp.net WebService

看到园子有位朋友需要使用AFN框架请求 WebService，所以就整理了一下，demo下载链接在底部

编写WebService可以看这篇博客 http://www.cnblogs.com/linmingjun/p/4606451.html

//使用AFN请问无参方法

    AFHTTPRequestOperation *operation =[[AFHTTPRequestOperation alloc] initWithRequest:request];

    [operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {

        //返回字符串

        NSString *html = operation.responseString;

        NSLog(@"html----%@",html);

iOS网络开发-AFNetworking请求asp.net WebService


在使用.Net Web服务编写WebService,如上图我们可以看到返回的数据，前后数据多出了


<?xml version=\"1.0\" encoding=\"utf-8\"?>


<string xmlns=\"http://tempuri.org/\">


</string>
所以在得到json格式的数据的时候，先把前后多余的数据给替换了设置为空。
完整案例数据解析过程 NSString->NSData->NSarray
