将压缩包中的文件夹拖入xcode工程项目中并引入如下的框架

 

简单的 JOSN 解析例子
    static NSString *serverAddress = @"http://m.weather.com.cn/data/101110101.html";

　 // 1.创建JSON操作对象
    AFJSONRequestOperation *operation =
    [AFJSONRequestOperation
     JSONRequestOperationWithRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:serverAddress]]
     success:^(NSURLRequest *request, NSHTTPURLResponse *response, id JSON) {
         NSLog(@"success -- %@", JSON);
     } failure:^(NSURLRequest *request, NSHTTPURLResponse *response, NSError *error, id JSON) {
         NSLog(@"failure -- %@", JSON);
     }];

 

    // 2.执行对象的操作异步加载
    [operation start];

 

简单的 XML 解析例子

    static NSString *serverAddress = @"http://flash.weather.com.cn/wmaps/xml/beijing.xml";
    
    // 1.创建XML操作对象
    AFXMLRequestOperation *operation =
    [AFXMLRequestOperation
     XMLParserRequestOperationWithRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:serverAddress]]
     success:^(NSURLRequest *request, NSHTTPURLResponse *response, NSXMLParser *XMLParser) {
         NSLog(@"success -- %@", XMLParser);
     }
     failure:^(NSURLRequest *request, NSHTTPURLResponse *response, NSError *error, NSXMLParser *XMLParser) {
         NSLog(@"failure -- %@", XMLParser);
     }];

    // 2.执行对象的操作异步加载
    [operation start];

HTTP POST请求例子

-----------------------------------------------------------------------------------------------------

//内联函数

NS_INLINE AFHTTPClient * createAFHTTPClient(NSString *baseURLString)
{
    //创建一个AFHTTPClient的链接,仅需传入服务器URL的String即可
    return [AFHTTPClient clientWithBaseURL:[NSURL URLWithString:baseURLString]];
}

NS_INLINE NSData * createJSONDataFromDict(NSDictionary *params)
{
    //根据字典创建出JSON专用格式的NSData
    return [NSJSONSerialization dataWithJSONObject:params
                                           options:NSJSONWritingPrettyPrinted
                                             error:nil];
}

-----------------------------------------------------------------------------------------------------

//服务器地址
    static NSString *serverAddress = @"http://art.wooboo.com.cn/support/service.shtml";
    
    //初始化一个本地的httpClient
    AFHTTPClient *httpClient = createAFHTTPClient(serverAddress);
    
    //完善httpClient并形成一个POST请求报文
    NSURLRequest *request = [httpClient multipartFormRequestWithMethod:@"POST"
                                                                  path:serverAddress
                                                            parameters:nil
    constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
        
        
        NSArray *paramsType = @[@{@"action": @"loadImg", @"artId": @"0"}];
        
        
        //转换字典数据为JSON专用格式并再次转换为字符串
        NSString *params = [[NSString alloc] initWithData:
                            createJSONDataFromDict(paramsType[0])
                                                 encoding:NSUTF8StringEncoding];
        
        
        //进一步完善请求的内容 (Content-Disposition: form-data; name=#{name}")
        [formData appendPartWithFormData:[params dataUsingEncoding:NSUTF8StringEncoding]
                                    name:@"p"];
    }];
    
    
    //将请求报文发送到服务器进行链接
    AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:request];
    [operation
     setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {
         
         
         NSLog(@"%@", jsonObjectFromData(responseObject));
         
         
     } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
         
         NSLog(@"error.");
         
     }];
    [operation start];
