Restkit 0.20基本操作
我刚刚开始使用RestKit，并且已经到达RK0.20即将上线的时候，文档和演示已经落后了一步。网络上的大多数东西都是RK 0.10版本的，而0.20版本有很大的变化。
我不想退回到更早的版本，因为新的版本很快就会启动并运行。
我在网址"test.myserver.com“处有一个JSON资源，它返回一个简单的数据报-{ "id_user"："4401"，"datalocation"："4401"，"country"：”Britain Britain“，"data"："testdata"，"login"："Fred Bloggs"，"password"："579c0cb0ed2dc25db121283f7a98cc71"，"accessLevel"："2"，"timestamp"："1012"，"datahash"：”2749da29f20ce7a850923f193adee8“}
我非常确定我已经对Mappings等进行了排序，但是我的服务需要身份验证，所以我需要在请求中向服务器传递用户名和密码。
到目前为止我已经得到了这个
NSURL *url = [NSURL URLWithString:@"http://test.myserver.com"];
NSURLRequest *request = [NSURLRequest requestWithURL:url];
RKObjectRequestOperation *objectRequestOperation = [[RKObjectRequestOperation alloc] initWithRequest:request responseDescriptors:@[ responseDescriptor ]];
[objectRequestOperation setCompletionBlockWithSuccess:^(RKObjectRequestOperation *operation, RKMappingResult *mappingResult) {
RKLogInfo(@"Load collection of Articles: %@", mappingResult.array);
} failure:^(RKObjectRequestOperation *operation, NSError *error) {
RKLogError(@"Operation failed with error: %@", error);
}];
[objectRequestOperation start];它似乎要联系服务器，但不可避免地会记录以下错误
restkit.network:RKObjectRequestOperation.m:296对象请求失败:底层HTTP请求操作失败，错误信息代码=-1011“(200-299)中的预期状态代码，got 401”UserInfo=0x7884030 {“NSLocalizedRecoverySuggestion={”Domain=org.restkit.RestKit.ErrorDomain“：{”代码“：401，"message"：”未授权:需要身份验证“} }，AFNetworkingOperationFailingURLRequestErrorKey=http://elancovision.umfundi.com>，NSErrorFailingURLKey=http://elancovision.umfundi.com，(200-299)中的NSLocalizedDescription=Expected状态代码，got 401，AFNetworkingOperationFailingURLResponseErrorKey=}
当然，问题是如何将用户名和密码添加到请求中。
对于菜鸟的问题，我很抱歉！

对于基本HTTP身份验证，应该将用户名和密码插入到每个请求的HTTP请求授权标头字段中。
首先，我建议您使用RKObjectManager来集中配置请求和映射。http://restkit.org/api/latest/Classes/RKObjectManager.html RKObjectManager可以存储网络参数(通过AFNetworking库)，然后根据用户名/密码、路径、对象映射建立适当的http查询。
改编你的例子，它会给出类似这样的结果：
NSURL* url = [[NSURL alloc]initWithString:@"http://test.myserver.com"];
RKObjectManager* objectManager = [RKObjectManager managerWithBaseURL:url];
[objectManager.HTTPClient setAuthorizationHeaderWithUsername:@"username" password:@"password"];
//NSURLRequest *request = [NSURLRequest requestWithURL:url];
NSURLRequest *request = [objectManager requestWithObject:nil method:RKRequestMethodGET path:@"/yourAPI/yourmethod" parameters:nil];
RKObjectRequestOperation *objectRequestOperation = [[RKObjectRequestOperation alloc] initWithRequest:request responseDescriptors:@[ responseDescriptor ]];
[objectRequestOperation setCompletionBlockWithSuccess:^(RKObjectRequestOperation *operation, RKMappingResult *mappingResult) {
RKLogInfo(@"Load collection of Articles: %@", mappingResult.array);
} failure:^(RKObjectRequestOperation *operation, NSError *error) {
RKLogError(@"Operation failed with error: %@", error);
}];
[objectRequestOperation start];如果身份验证工作正常，那么查看一下RESTKit wiki就会给出构建正确映射的下一个提示：https://github.com/RestKit/RestKit/wiki/Object-mapping

我的解决方案是：
// Build a RestKit manager object to look after the restful stuff
RKObjectManager *manager = [RKObjectManager managerWithBaseURL:[NSURL URLWithString:@"http://test.myserver.com"]];;
// Hash the GUI input password string and pass the username in plain text
NSString *md5PW = [umfundiCommon md5:passwordField.text];
[manager.HTTPClient setAuthorizationHeaderWithUsername:userField.text password:md5PW];
RKObjectMapping *WebResponse = [RKObjectMapping mappingForClass:[WSObject class]];
[WebResponse addAttributeMappingsFromDictionary:@{@"id_user":@"id_user", @"datalocation": @"datalocation", @"country":@"country", @"data": @"data", @"login": @"login", @"password": @"password", @"accessLevel": @"accessLevel", @"timestamp": @"timestamp", @"datahash": @"datahash"}];
RKResponseDescriptor *responseDescriptor = [RKResponseDescriptor responseDescriptorWithMapping:WebResponse pathPattern:nil keyPath:nil statusCodes:RKStatusCodeIndexSetForClass(RKStatusCodeClassSuccessful)];
// Add the above response descriptor to the manager
[manager addResponseDescriptor:responseDescriptor];
// the getObject makes the call using the stuff assembled into the manager Object and drops into either the success or the failure routines.
[manager getObject:nil path:@"" parameters:nil success:^(RKObjectRequestOperation *operation, RKMappingResult *result)
{
NSLog (@"Server WS call success:");
NSArray *theresults = [result array];
for (WSObject *item in theresults) {
NSLog(@"datahash=%@",item.datahash);
NSLog(@"user_id=%@",item.id_user);
}
} failure:^(RKObjectRequestOperation * operation, NSError * error)
{
NSLog (@"Server WS call failure: operation: %@ \n\nerror: %@", operation, error);
}];
