Demo

I found a bug at iOS 12.2 or newer version  with UIWebView.

1. create a UIWebView with  mediaPlaybackRequiresUserAction=YES;

self.webView.mediaPlaybackRequiresUserAction = YES;

It means， Video only can be play while User  click it.


2. Make my iPhone to "Low Power Mode"


3. Open a web with the UIWebView

I write a Video tag:

<video controls id="videoo" src="http://image.uc.cn/s/uae/g/0n/iosvideo/video.mp4"></video>


4. When I click the Video's default Play Button, it can not be play.


It works well at Safari and iOS 12.


You can build the Demo to a iOS 12.2 or newer version  iPhone to try it.
