1.需求:国内几大常见的社交分享
(只写了具体分享操作的代码,前期的配置和Appdeltegate中的回调url以及第三方注册的相关方法已省略,需要自己添加)
2.SSSocialMessageObject是自己封装的分享对象,按照需求自己定义,包括title,thumImage,url,text(摘要)等
3.有些分享参数不符合条件可能会意外埋坑,比如微信,见代码注释
/**
具体分享操作
@param platformType 平台类型
@param messageObject 具体分享的对象
@param currentViewController 某些平台需要传的参数
@param completion 分享完成回调
