Mobile Safari中Javascript中的麦克风访问

Question

我正在尝试在网页中实现对Java麦克风的访问，

同时使用navigator.getUserMedia({audio: true})或navigator.mediaDevices.getUserMedia({audio:true})

（（并检查供应商前缀：

navigator.getUserMedia = navigator.getUserMedia || navigator.webkitGetUserMedia || navigator.mozGetUserMedia || navigator.msGetUserMedia;）

响应于页面上按钮的点击事件而调用

似乎在IOS Safari中不起作用。 （在桌面版Chrome中可以正常运行）。

但是，these guys在这里似乎可以正常工作-它可以在我的iPhone上的Safari上运行。

他们在做什么不同？
