1.實現微博第三方登入，首先要在”新浪開發者平臺”註冊，登入。

http://open.weibo.com

2.建立應用：
微連線->立即建立微連線->移動應用->填寫資料(教程可以去以下網址下載)

https://github.com/sinaweibosdk/weibo_ios_sdk

3.下載完成後，看 “微博iOS平臺SDK文件V3.1.1.pdf” 這個文件。文件中有如何教你配置檔案，但是WeiboSDK支援使用Cocoapods整合，請在Podfile中新增以下語句：

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

跟著”微博iOS平臺SDK文件V3.1.1.pdf” 這個文件，完成”一.SDK接入設定”中的 1，2，3，4，8，9，10
至此，檔案配置完成。
4.我們需要做的是第三方登入，即: “認證授權”
看”二.應用場景程式碼示例”中的 “1.SSO微部落格戶端授權認證”。

5.微博API文件

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

WeiboSDK->sendRequest->Discussion
( 請求傳送給微部落格戶端程式之後，微部落格戶端程式會進行相關的處理，處理完成之後一定會呼叫 [WeiboSDKDelegate didReceiveWeiboResponse:] 方法將處理結果返回給第三方應用)

所以在APPDelegate中，我們還需要遵循 “WeiboSDKDelegate”協議，這兩個協議中有兩個必須實現的方法，分別是:

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(@"傳送結果", nil);
        NSString *message = [NSString stringWithFormat:@"%@: %d\n%@: %@\n%@: %@", NSLocalizedString(@"響應狀態", nil), (int)response.statusCode, NSLocalizedString(@"響應UserInfo資料", nil), response.userInfo, NSLocalizedString(@"原請求UserInfo資料", nil),response.requestUserInfo];
        UIAlertView *alert = [[UIAlertView alloc] initWithTitle:title
                                                        message:message
                                                       delegate:nil
                                              cancelButtonTitle:NSLocalizedString(@"確定", 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(@"認證結果", nil);
        NSString *message = [NSString stringWithFormat:@"%@: %d\nresponse.userId: %@\nresponse.accessToken: %@\n%@: %@\n%@: %@", NSLocalizedString(@"響應狀態", nil), (int)response.statusCode,[(WBAuthorizeResponse *)response userID], [(WBAuthorizeResponse *)response accessToken],  NSLocalizedString(@"響應UserInfo資料", nil), response.userInfo, NSLocalizedString(@"原請求UserInfo資料", nil), response.requestUserInfo];
        UIAlertView *alert = [[UIAlertView alloc] initWithTitle:title
                                                        message:message
                                                       delegate:nil
                                              cancelButtonTitle:NSLocalizedString(@"確定", 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(@"支付結果", nil);
        NSString *message = [NSString stringWithFormat:@"%@: %d\nresponse.payStatusCode: %@\nresponse.payStatusMessage: %@\n%@: %@\n%@: %@", NSLocalizedString(@"響應狀態", nil), (int)response.statusCode,[(WBPaymentResponse *)response payStatusCode], [(WBPaymentResponse *)response payStatusMessage], NSLocalizedString(@"響應UserInfo資料", nil),response.userInfo, NSLocalizedString(@"原請求UserInfo資料", nil), response.requestUserInfo];
        UIAlertView *alert = [[UIAlertView alloc] initWithTitle:title
                                                        message:message
                                                       delegate:nil
                                              cancelButtonTitle:NSLocalizedString(@"確定", nil)
                                              otherButtonTitles:nil];
        [alert show];
    }
    else if([response isKindOfClass:WBSDKAppRecommendResponse.class])
    {
        NSString *title = NSLocalizedString(@"邀請結果", nil);
        NSString *message = [NSString stringWithFormat:@"accesstoken:\n%@\nresponse.StatusCode: %d\n響應UserInfo資料:%@\n原請求UserInfo資料:%@",[(WBSDKAppRecommendResponse *)response accessToken],(int)response.statusCode,response.userInfo,response.requestUserInfo];
        UIAlertView *alert = [[UIAlertView alloc] initWithTitle:title
                                                        message:message
                                                       delegate:nil
                                              cancelButtonTitle:NSLocalizedString(@"確定", nil)
                                              otherButtonTitles:nil];
        [alert show];
    }
}

至此，我們已經實現了第三方登入了！
但是，怎麼才能獲得相關的資料呢?
//參考如下:

 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
{
    //此處不需要使用匯入第三方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);
}
