例如:wb204543436852

六、编写代码

1、在Appdelegate中导入头文件，声明遵循微博代理

#import <UIKit/UIKit.h>
#import "WeiboSDK.h"

#define kAppKey         @"这里是你的AppKey"
#define kRedirectURI    @"这里是你的回调网址"

@interface AppDelegate : UIResponder <UIApplicationDelegate, WeiboSDKDelegate>

@property (strong, nonatomic) UIWindow *window;

@end

2、在Appdeleg ate中注册微博SDK

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    // Override point for customization after application launch.
    
    [WeiboSDK enableDebugMode:YES];
    [WeiboSDK registerApp:@"这里填写你申请的Appkey"];
    
    return YES;
}

3、重写AppDelegate中的handleOpen URL和openURL方法

- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation
{
    return [WeiboSDK handleOpenURL:url delegate:self];
}

- (BOOL)application:(UIApplication *)application handleOpenURL:(NSURL *)url
{
    return [WeiboSDK handleOpenURL:url delegate:self];
}

4、在你所要添加登录方法的controller中添加以下登录方法，该方法会跳转微博授权

- (void)weiboLoginButtonPressed
{
    NSLog(@"%s",__func__);
    
    WBAuthorizeRequest *request = [WBAuthorizeRequest request];
    request.redirectURI = kRedirectURI;
    request.scope = @"all";
    request.userInfo = @{@"SSO_From": @"SendMessageToWeiboViewController",
                         @"Other_Info_1": [NSNumber numberWithInt:123],
                         @"Other_Info_2": @[@"obj1", @"obj2"],
                         @"Other_Info_3": @{@"key1": @"obj1", @"key2": @"obj2"}};
    [WeiboSDK sendRequest:request];
}

5、在Appdelegate中实现微博的回调方法，获取回调信息

这里说明一下，下面的方法实现在Appdelegate中，当在你所需登录的controller调用的登录方法后会跳转微博进行授权，授权信息会以回调的方式调用Appdelegate中的下面方法，从该方法中我们可以得出授权所得到的userId（用户唯一标识），和accessToken。拿到这两个参数后可以调用微博接口进行一系列的获取个人信息、转发、评论、发表微博等操作，这里我们只需要获取用户的个人信息就可以了。

//微博回调
- (void)didReceiveWeiboResponse:(WBBaseResponse *)response
{
    if ([response isKindOfClass:WBAuthorizeResponse.class])
    {
        NSString *userId = [(WBAuthorizeResponse *)response userID];
        NSString *accessToken = [(WBAuthorizeResponse *)response accessToken];
        
        NSLog(@"userId %@",userId);
        NSLog(@"accessToken %@",accessToken);
        
        NSDictionary *notification = @{
                                       @"userId" : userId,
                                       @"accessToken" : accessToken
                                       };
        
        [[NSNotificationCenter defaultCenter] postNotificationName:@"weiboDidLoginNotification" 
                                              object:self userInfo:notification];
    }
}

当获取到 反馈的userID和accessToken后，这里我使用了通知Notification的方式来调用刚才申请第三方登录的controller中的相应的方法。记得使用通知的时候在dealloc方法中进行通知的删除。

6、在实现登录的controller中的相应的通知方法中实现以下功能

用刚刚在微博的回调方法中得到的userId和accessToken来请求微博的接口以获取用户的个人信息

https://api.weibo.com/2/users/show.json

#pragma mark - Weibo Methods

- (void)weiboDidLoginNotification:(NSNotification *)notification
{
    NSLog(@"%s",__func__);
    
    NSDictionary *userInfo = [notification userInfo];
    NSString *accessToken = [userInfo objectForKey:@"accessToken"];
    NSString *uid = [userInfo objectForKey:@"userId"];
    
    NSLog(@"userInfo %@",userInfo);
    
    [self getWeiboUserInfoWithAccessToken:accessToken uid:uid];
}

- (void)getWeiboUserInfoWithAccessToken:(NSString *)accessToken uid:(NSString *)uid
{
    NSString *url =[NSString stringWithFormat:
    @"https://api.weibo.com/2/users/show.json?access_token=%@&uid=%@",accessToken,uid];
    
    dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{
        NSURL *zoneUrl = [NSURL URLWithString:url];
        NSString *zoneStr = [NSString stringWithContentsOfURL:zoneUrl 
                                                     encoding:NSUTF8StringEncoding error:nil];
        NSData *data = [zoneStr dataUsingEncoding:NSUTF8StringEncoding];
        dispatch_async(dispatch_get_main_queue(), ^{
            if (data)
            {
                NSDictionary *dic = [NSJSONSerialization JSONObjectWithData:data 
                                                                    options:NSJSONReadingMutableContainers error:nil];
                
                NSLog(@"%@",dic);
                
                NSString *openId = [dic objectForKey:@"id"];
                NSString *memNickName = [dic objectForKey:@"name"];
                NSString *memSex = [[dic objectForKey:@"gender"] isEqualToString:@"m"] ? @"1" : @"0";
                
                [self loginWithOpenId:openId memNickName:memNickName memSex:memSex];
            }
        });
        
    });
}

至此，已经获取到了用户微博的UserI d及用户其他的基本信息，用这些信息就可以进行与自己的服务端进行交互来实现第三方登录了。
