ios 关于版本更新和判断苹果是否在审核，获取版本信息不准的说明

获取app在 App Store上的json信息url

国外：https://itunes.apple.com/lookup?id=xxx

国内：https://itunes.apple.com/cn/lookup?id=xxx

首先讲下获取版本信息不准情况：用GET请求，就会出现信息不准，解决办法就是用POST请求。国外和国内地址都请求一遍，获取两个json数据里的字段“*currentVersionReleaseDate”最新日期的json*

判断苹果是否在审核逻辑：根据app当前版本对比AppStore上版本，如果大于AppStore上版本，就是在审核（开发环境除外）
