• 現(xiàn)在這個功能大部分人都是用UM和share去做的，今天我們以來回味下原味道

新浪登錄

• 新浪API網(wǎng)址大全：http://open.weibo.com/wiki/API%E6%96%87%E6%A1%A3_V2，這里我們知道獲取完參數(shù)后各個信息的請求接口
• 新浪SDK下載地址: http://open.weibo.com/wiki/SDK
• 集成的注意點：
• 1、首先肯定是去新浪開發(fā)者平臺去創(chuàng)建應(yīng)用，申請appKey，這一段這里不再啰嗦，大概他們會審一天的樣子，所以建議大家提前做這事
• 2、審核通過，拿到key以后，去下載SDK包，把SDK包中的libWeiboSDK文件夾添加到工程中去。
• 3、工程中我們需要配置三處地方：第一處添加URLScheme：是wb+你微博應(yīng)用的appkey（比如wb2045436852）。第二處：添加系統(tǒng)動態(tài)包，QuartzCore.framework,ImageIO.framework, SystemConfiguration.framework, Security.framework, CoreTelephony.framework, CoreText.framework, CoreGraphics.framework, libz.tbd, libsqlite3.tbd。 第三處：在系統(tǒng)的infoplist文件中添加白名單，LSApplicationQueriesSchemes中添加名單weibosdk2.5, weibosdk,sinaweibohd, sinaweibo。（如果你的服務(wù)器還沒有ssl證書，你還需要設(shè)置下網(wǎng)絡(luò)App Transport Security Settings這里的tran..為YES）
• 4、OK，環(huán)境配置完成。接下來是代碼了：appdelegate中,要做的事大概是：向新浪開發(fā)者注冊，判斷應(yīng)用是否是被新浪的回調(diào)打開，實現(xiàn)代理，查新浪API，獲取用戶新浪信息

- (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有時候不走，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（當(dāng)然，實際開發(fā)中這個代理肯定給某個工具類），并實現(xiàn)代理方法

- (void)didReceiveWeiboResponse:(WBBaseResponse *)response
{
if ([response isKindOfClass:WBAuthorizeResponse.class])
    {
    // 登錄的回調(diào)這里
    [self getWeiBoUserInfo:response.userInfo]; // 查微博API，請求用戶的微信信息
    }
}
- (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，剩下的只要寫個btn調(diào)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];

• 將iOS SDK中的TencentOpenAPI.framework和TencentOpenApi_IOS_Bundle.bundle文件拷貝到應(yīng)用開發(fā)的目錄下
• 添加SDK依賴的系統(tǒng)庫文件。分別是”Security.framework”, “l(fā)ibiconv.dylib”，“SystemConfiguration.framework”，“CoreGraphics.Framework”、“l(fā)ibsqlite3.dylib”、“CoreTelephony.framework”、“l(fā)ibstdc++.dylib”、“l(fā)ibz.dylib”
• 需要注意的地方：info中添加URLTypes格式是：比如tencent1105042374。tencent+appid
• 設(shè)置網(wǎng)絡(luò)請求，兼容http
• 添加各種白名單

• appdelegate中，

{
    if ([url.host isEqualToString:@"qzapp"]) {
        // 從qq跳回來的
        [TencentOAuth HandleOpenURL:url];
    }
    return YES;

微信登錄

• 1、大概流程是：先去注冊應(yīng)用，然后交錢，申請開通微信登錄功能
• 2、審核通過，拿到微信應(yīng)用的AppKey和AppScroet
• 3、系統(tǒng)環(huán)境配置，基本上只要再在上面的基礎(chǔ)上加一個Scheme（wxf707ade9f9ff3ebb 這個和新浪挺想象的）就可以了
• 4、在appdelegate中注冊微信App，遵守微信代理，并且實現(xiàn)代理方法
• 5、AppDelegate中關(guān)鍵代碼如下

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    // 注冊微信
    [WXApi registerApp:kWeiChatAppId withDescription:@"微信"];    
    return YES;
}
// 接受微信回調(diào)方法
- (BOOL)application:(UIApplication *)app openURL:(NSURL *)url options:(NSDictionary<NSString *,id> *)options
{
   if([url.host isEqualToString:@"oauth"]){
        // 從微信跳回來的
        [WXApi handleOpenURL:url delegate:self];
    }
    return YES;
}
// 微信代理方法
-(void)onResp:(BaseResp*)resp{
    // SendAuthResp是微信登錄
    if ([resp isKindOfClass:[SendAuthResp class]]) {
        SendAuthResp *authResp = (SendAuthResp *)resp;
        // 調(diào)用工具類，獲取用戶的基本數(shù)據(jù)
        [[GetUserInfo sharedInstance] getUserWXInfoByCode:authResp.code];
    }
}

• 5、寫個button調(diào)用微信登錄

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

• 6、至于獲取用戶的微信信息，這個和新浪一模一樣，都是在代理方法中獲取到access_token和一個類似uid一樣的，然后去找API接口
