今天更新版本之后APP Stroe上面显示的是最新版（Version1.8.1），APP（Version1.8.0）应该提示立即更新，但是并没有。
检查代码发现：
https://itunes.apple.com/cn/lookup?id=(YourAppID)
lookup?id 这个接口请求的数据 版本是1.8.0
换个接口试下：
https://itunes.apple.com/lookup?bundleId=(YourAppBundleID)
lookup?bundleId 这个接口请求的数据 版本是1.8.1
根据APP的BundleId从iTunes获取版本信息对比更新
2016年12月22日更新：
以BundleId获取APP信息：https://itunes.apple.com/lookup?bundleId=com.tencent.xin
返回的信息中包括版本号(version)、trackId(即iTunes id)、更新信息(releaseNotes)、描述(description)、屏幕截图(screenshotUrls)等。
使用这个接口，可以在APP一开始就部署更新机制，未上架时请求返回的数据是：
{
"resultCount":0,
"results": []
}
上架后可以根据results里的version字段值，比较后提示更新。
请求返回的数据是：
