iOS微博授权登录

微博开放平台：传送门
官方提供的Demo：传送门

第一步：申请微博开放平台移动应用

先要在开放平台注册并创建应用并配置Bundle ID，这里就不赘述了
应用创建成功后会获得AppKey，记录并备用

第二步：集成SDK到工程

将从GitHub上下载的libWeiboSDK文件夹添加至工程，SDK包含4个文件：
WeiboSDK.h
WBHttpRequest.h
libWeiboSDK.a
WeiboSDK.bundle

另外还要引入以下系统库：
QuartzCore.framework
ImageIO.framework
SystemConfiguration.framework
Security.framework
CoreTelephony.framework
CoreText.framework
UIKit.framework
Foundation.framework
CoreGraphics.framework
libz.tbd
libsqlite3.tbd
WebKit.framework

第三步：配置URL Scheme

打开Xcode选择project → Info → URL Types → 新增一个，URL Schemes填wb+AppKey（例如AppKey为204543436852，则URL Schemes为wb204543436852）

第四步：配置LSApplicationQueriesSchemes

打开Xcode找到info.plist，右击选择open as → source code
将下面代码添加进去：

<key>LSApplicationQueriesSchemes</key>
<array>
   <string>sinaweibohd</string>
   <string>sinaweibo</string>
   <string>weibosdk</string>
   <string>weibosdk2.5</string>
</array>

第五步：向微博客户端程序注册并初始化

使用第一步中获得的AppKey初始化WeiboSDK

[WeiboSDK enableDebugMode:YES]; //设置调试模式
[WeiboSDK registerApp:@"wb204543436852"];

第六步：发起SSO客户端授权认证

WBAuthorizeRequest *request = [WBAuthorizeRequest request];
request.redirectURI = kRedirectURI;
request.scope = @"all";

request.userInfo = @{@"SSO_From": @"ViewControllerClassName",
                     @"Other_Info_1": [NSNumber numberWithInt:123],
                     @"Other_Info_2": @[@"obj1", @"obj2"],
                     @"Other_Info_3": @{@"key1": @"obj1", @"key2": @"obj2"}};
[WeiboSDK sendRequest:request];

在AppDelegate.m中获取回调

- (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 ];
}

- (void)didReceiveWeiboResponse:(WBBaseResponse *)response{
    
    if ([response isKindOfClass:WBAuthorizeResponse.class]){
        
        WBAuthorizeResponse *authorizeResponse = (WBAuthorizeResponse *)response;
        
        if(authorizeResponse.statusCode == WeiboSDKResponseStatusCodeSuccess){
            
            NSLog(@"用户ID = %@", authorizeResponse.userID);
            NSLog(@"自定义信息字典 = %@", authorizeResponse.userInfo);
        }
    }
}
