为什么iPhone将Google Chrome视为Safari还将Mozilla Firefox视为Safari浏览器？

Question

我创建了一个代码，用于检查浏览器是否只能在Google Chrome上访问并限制Mozilla Firefox。例如，我使用的只是使用谷歌浏览器的Android手机，如果iPhone或iPad Google Chrome浏览器有权访问该网站。但是，当检查浏览器是Chrome还是Mozilla时，它会被视为Safari。使用C＃，工具。所以我调查它是否有一个独特的财产，很好用，但可悲的是没有。有没有一个好的插件或库或框架来检测iPhone或Android浏览器。谢谢。

这是用于谷歌浏览器。

这可能是由于iOS不允许其他浏览器引擎比Safari。

不幸的是，这迫使Chrome应用程序使用Safari的Web浏览器组件和用户代理。
