IOS项目集成ShareSDK实现第三方登录、分享、关注等功能（转）

原文链接：http://blog.csdn.net/daleiwang/article/details/34081231

（1）官方下载ShareSDK iOS 2.8.8，地址：http://sharesdk.cn/

（2）根据实际情况，引入相关的库，参考官方文档。

（3）在项目的AppDelegate中一般情况下有三个操作，第一是注册ShareSDK，第二是注册各个平台的账号，第三是关于微信等应用的回调处理。

（5）你可能会看到一些应用需要第三方登录的，一种是弹出webView加载的新浪微博或者qq的网页授权，还有一种是跳转到本地的已经安装的新浪微博应用或者qq应用进行授权。第二种授权方式较SSO授权，体验会比较好一些，因为不需要用户输入新浪微博或QQ的用户名与密码。

第二种授权方式需要在plist中配置Scheme。SSO默认是打开的不需要配置。在AppDelegate中实现回调。
