iOS微信浏览器无法使用navigator.mediaDevices吗?navigator.mediaDevices 在iOS的内置浏览器中无法使用,这个有什么解决方法吗?
2024-01-03直接在video标签中加 playsinline和webkit-playsinline="true" 这两个就行
小程序调H5,navigator.mediaDevices.getUserMedia在IOS不能用?微信小程序web-view调用H5页面,H5页面navigator.mediaDevices.getUserMedia调用摄像头在ios手机微信上不能用,有没有已经搞定的,或者其他解决方法的
