ios 微博第三方登录及得到相关参数

1.实现微博第三方登录，首先要在”新浪开发者平台”注册，登录。

http://open.weibo.com

2.创建应用：
微连接->立即创建微连接->移动应用->填写资料(教程可以去以下网址下载)

https://github.com/sinaweibosdk/weibo_ios_sdk

3.下载完成后，看 “微博iOS平台SDK文档V3.1.1.pdf” 这个文档。文档中有如何教你配置文件，但是WeiboSDK支持使用Cocoapods集成，请在Podfile中添加以下语句：

pod "WeiboSDK", :git => "https://github.com/sinaweibosdk/weibo_ios_sdk.git" 

跟着”微博iOS平台SDK文档V3.1.1.pdf” 这个文档，完成”一.SDK接入设置”中的 1，2，3，4，8，9，10
至此，文件配置完成。
4.我们需要做的是第三方登录，即: “认证授权”
看”二.应用场景代码示例”中的 “1.SSO微博客户端授权认证”。

5.微博API文档

http://sinaweibosdk.github.io/weibo_ios_sdk/index.html

WeiboSDK->sendRequest->Discussion
( 请求发送给微博客户端程序之后，微博客户端程序会进行相关的处理，处理完成之后一定会调用 [WeiboSDKDelegate didReceiveWeiboResponse:] 方法将处理结果返回给第三方应用)

所以在APPDelegate中，我们还需要遵循 “WeiboSDKDelegate”协议，这两个协议中有两个必须实现的方法，分别是:

didReceiveWeiboRequest:didReceiveWeiboResponse:

//以下是demo中的示例：- (void)didReceiveWeiboRequest:(WBBaseRequest *)request{}- (void)didReceiveWeiboResponse:(WBBaseResponse *)response{    if ([response isKindOfClass:WBSendMessageToWeiboResponse.class])    {        NSString *title = NSLocalizedString(@"发送结果", nil);        NSString *message = [NSString stringWithFormat:@"%@: %d\n%@: %@\n%@: %@", NSLocalizedString(@"响应状态", nil), (int)response.statusCode, NSLocalizedString(@"响应UserInfo数据", nil), response.userInfo, NSLocalizedString(@"原请求UserInfo数据", nil),response.requestUserInfo];        UIAlertView *alert = [[UIAlertView alloc] initWithTitle:title                                                        message:message                                                       delegate:nil                                              cancelButtonTitle:NSLocalizedString(@"确定", nil)                                              otherButtonTitles:nil];        WBSendMessageToWeiboResponse* sendMessageToWeiboResponse = (WBSendMessageToWeiboResponse*)response;        NSString* accessToken = [sendMessageToWeiboResponse.authResponse accessToken];        if (accessToken)        {            self.wbtoken = accessToken;        }        NSString* userID = [sendMessageToWeiboResponse.authResponse userID];        if (userID) {            self.wbCurrentUserID = userID;        }        [alert show];    }    else if ([response isKindOfClass:WBAuthorizeResponse.class])    {        NSString *title = NSLocalizedString(@"认证结果", nil);        NSString *message = [NSString stringWithFormat:@"%@: %d\nresponse.userId: %@\nresponse.accessToken: %@\n%@: %@\n%@: %@", NSLocalizedString(@"响应状态", nil), (int)response.statusCode,[(WBAuthorizeResponse *)response userID], [(WBAuthorizeResponse *)response accessToken],  NSLocalizedString(@"响应UserInfo数据", nil), response.userInfo, NSLocalizedString(@"原请求UserInfo数据", nil), response.requestUserInfo];        UIAlertView *alert = [[UIAlertView alloc] initWithTitle:title                                                        message:message                                                       delegate:nil                                              cancelButtonTitle:NSLocalizedString(@"确定", nil)                                              otherButtonTitles:nil];        self.wbtoken = [(WBAuthorizeResponse *)response accessToken];        self.wbCurrentUserID = [(WBAuthorizeResponse *)response userID];        self.wbRefreshToken = [(WBAuthorizeResponse *)response refreshToken];        [alert show];    }    else if ([response isKindOfClass:WBPaymentResponse.class])    {        NSString *title = NSLocalizedString(@"支付结果", nil);        NSString *message = [NSString stringWithFormat:@"%@: %d\nresponse.payStatusCode: %@\nresponse.payStatusMessage: %@\n%@: %@\n%@: %@", NSLocalizedString(@"响应状态", nil), (int)response.statusCode,[(WBPaymentResponse *)response payStatusCode], [(WBPaymentResponse *)response payStatusMessage], NSLocalizedString(@"响应UserInfo数据", nil),response.userInfo, NSLocalizedString(@"原请求UserInfo数据", nil), response.requestUserInfo];        UIAlertView *alert = [[UIAlertView alloc] initWithTitle:title                                                        message:message                                                       delegate:nil                                              cancelButtonTitle:NSLocalizedString(@"确定", nil)                                              otherButtonTitles:nil];        [alert show];    }    else if([response isKindOfClass:WBSDKAppRecommendResponse.class])    {        NSString *title = NSLocalizedString(@"邀请结果", nil);        NSString *message = [NSString stringWithFormat:@"accesstoken:\n%@\nresponse.StatusCode: %d\n响应UserInfo数据:%@\n原请求UserInfo数据:%@",[(WBSDKAppRecommendResponse *)response accessToken],(int)response.statusCode,response.userInfo,response.requestUserInfo];        UIAlertView *alert = [[UIAlertView alloc] initWithTitle:title                                                        message:message                                                       delegate:nil                                              cancelButtonTitle:NSLocalizedString(@"确定", nil)                                              otherButtonTitles:nil];        [alert show];    }}

至此，我们已经实现了第三方登录了！
但是，怎么才能获得相关的数据呢?
//参考如下:

 AppDelegate * appdelegate = (AppDelegate *)[[UIApplication sharedApplication]delegate];    NSMutableDictionary * param = [[NSMutableDictionary alloc]initWithCapacity:2];    [param setObject:appdelegate.wbtoken forKey:@"access_token"];    [param setObject:appdelegate.wbCurrentUserID forKey:@"uid"];    NSString * userInfoUrl = @"https://api.weibo.com/2/users/show.json";    [WBHttpRequest requestWithAccessToken:appdelegate.wbtoken url:userInfoUrl httpMethod:@"GET" params:param delegate:self withTag:@"userInfo"];

- (void)request:(WBHttpRequest *)request didFinishLoadingWithDataResult:(NSData *)data{    //此处不需要使用导入第三方SBJson去解析data也可以    id d = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingAllowFragments error:nil];    NSDictionary * dict =  (NSDictionary *)d;//    NSLog(@"dict:%@",dict);    nameStr = [dict objectForKey:@"name"];    imageUrlStr = [dict objectForKey:@"profile_image_url"];    NSLog(@"name:%@,urlStr:%@",nameStr,imageUrlStr);}
