• 现在这个功能大部分人都是用UM和share去做的，今天我们以来回味下原味道

新浪登录

• 新浪API网址大全：http://open.weibo.com/wiki/API%E6%96%87%E6%A1%A3_V2，这里我们知道获取完参数后各个信息的请求接口
• 新浪SDK下载地址: http://open.weibo.com/wiki/SDK
• 集成的注意点：
• 1、首先肯定是去新浪开发者平台去创建应用，申请appKey，这一段这里不再啰嗦，大概他们会审一天的样子，所以建议大家提前做这事
• 2、审核通过，拿到key以后，去下载SDK包，把SDK包中的libWeiboSDK文件夹添加到工程中去。
• 3、工程中我们需要配置三处地方：第一处添加URLScheme：是wb+你微博应用的appkey（比如wb2045436852）。第二处：添加系统动态包，QuartzCore.framework,ImageIO.framework, SystemConfiguration.framework, Security.framework, CoreTelephony.framework, CoreText.framework, CoreGraphics.framework, libz.tbd, libsqlite3.tbd。 第三处：在系统的infoplist文件中添加白名单，LSApplicationQueriesSchemes中添加名单weibosdk2.5, weibosdk,sinaweibohd, sinaweibo。（如果你的服务器还没有ssl证书，你还需要设置下网络App Transport Security Settings这里的tran..为YES）
• 4、OK，环境配置完成。接下来是代码了：appdelegate中,要做的事大概是：向新浪开发者注册，判断应用是否是被新浪的回调打开，实现代理，查新浪API，获取用户新浪信息

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    [WeiboSDK enableDebugMode:YES];
    [WeiboSDK registerApp:@"1292878617"];
    return YES;
}
// 方法1
- (BOOL)application:(UIApplication *)app openURL:(NSURL *)url options:(NSDictionary<NSString *,id> *)options
{
    if ([url.host isEqualToString:@"response"]) {
        [WeiboSDK handleOpenURL:url delegate:self];
    }
    return YES;
}
// 方法1有时候不走，可以用以前的方法，也就是方法2
- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation
{
    return [WeiboSDK handleOpenURL:url delegate:self];
}

在appdelegate中遵守微博代理（当然，实际开发中这个代理肯定给某个工具类），并实现代理方法

- (void)didReceiveWeiboResponse:(WBBaseResponse *)response
{
if ([response isKindOfClass:WBAuthorizeResponse.class])
    {
    // 登录的回调这里
    [self getWeiBoUserInfo:response.userInfo]; // 查微博API，请求用户的微信信息
    }
}
- (void)getWeiBoUserInfo:(NSDictionary *)userDic
{
    NSString *access_token = userDic[@"access_token"];
    NSNumber *uid = userDic[@"uid"];
    NSString *paramter = [NSString stringWithFormat:@"access_token=%@&uid=%@", access_token, uid];
    NSString *baseUrl = @"https://api.weibo.com/2/users/show.json";
    NSString *urlStr = [baseUrl stringByAppendingFormat:@"?%@", paramter];
    NSURL *url = [NSURL URLWithString:urlStr];
    NSURLSession *session = [NSURLSession sharedSession];
    NSURLSessionDataTask *dataTask = [session dataTaskWithURL:url completionHandler:^(NSData * _Nullable data, NSURLResponse * _Nullable response, NSError * _Nullable error) {
        if (!error) {
            NSDictionary *dic = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingMutableLeaves error:nil];
            NSLog(@"1= %@", dic);
        }
    }];
    [dataTask resume];
}

• 5、然后就完全90%了，剩下的只要写个btn调用下方法就可以了

    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];

SDK下载地址：http://wiki.connect.qq.com/sdk%E4%B8%8B%E8%BD%BD#SDKfor.E7.A7.BB.E5.8A.A8.E5.BA.94.E7.94.A8.E6.8E.A5.E5.85.A5

• 将iOS SDK中的TencentOpenAPI.framework和TencentOpenApi_IOS_Bundle.bundle文件拷贝到应用开发的目录下
• 添加SDK依赖的系统库文件。分别是”Security.framework”, “libiconv.dylib”，“SystemConfiguration.framework”，“CoreGraphics.Framework”、“libsqlite3.dylib”、“CoreTelephony.framework”、“libstdc++.dylib”、“libz.dylib”
• 需要注意的地方：info中添加URLTypes格式是：比如tencent1105042374。tencent+appid
• 设置网络请求，兼容http
• 添加各种白名单

微信登录

• 1、大概流程是：先去注册应用，然后交钱，申请开通微信登录功能
• 2、审核通过，拿到微信应用的AppKey和AppScroet
• 3、系统环境配置，基本上只要再在上面的基础上加一个Scheme（wxf707ade9f9ff3ebb 这个和新浪挺想象的）就可以了
• 4、在appdelegate中注册微信App，遵守微信代理，并且实现代理方法
• 5、AppDelegate中关键代码如下

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    // 注册微信
    [WXApi registerApp:kWeiChatAppId withDescription:@"微信"];    
    return YES;
}
// 接受微信回调方法
- (BOOL)application:(UIApplication *)app openURL:(NSURL *)url options:(NSDictionary<NSString *,id> *)options
{
   if([url.host isEqualToString:@"oauth"]){
        // 从微信跳回来的
        [WXApi handleOpenURL:url delegate:self];
    }
    return YES;
}
// 微信代理方法
-(void)onResp:(BaseResp*)resp{
    // SendAuthResp是微信登录
    if ([resp isKindOfClass:[SendAuthResp class]]) {
        SendAuthResp *authResp = (SendAuthResp *)resp;
        // 调用工具类，获取用户的基本数据
        [[GetUserInfo sharedInstance] getUserWXInfoByCode:authResp.code];
    }
}

• 5、写个button调用微信登录

static NSString *kAuthScope = @"snsapi_message,snsapi_userinfo,snsapi_friend,snsapi_contact";
static NSString *kAuthState = @"xxx";
- (IBAction)login:(id)sender {
    // 调用微信登录
    SendAuthReq *req = [[SendAuthReq alloc] init];
    req.scope = kAuthScope;
    req.state = @"123";
    [WXApi sendReq:req];
}

• 6、至于获取用户的微信信息，这个和新浪一模一样，都是在代理方法中获取到access_token和一个类似uid一样的，然后去找API接口
