There is a brief pause after calling the javascript causing other elements on the screen to hiccup for a moment.

Detect video start playing in WKWebView

阅读更多关于 Detect video start playing in WKWebView

I'm using WKWebView for loading an youtube page. I need to detect the video starts playing in the webview in inline mode and in the full screen mode. I tried MPMoviePlayerController Notifiers but they are not calling. But the same is working in UIWebView.
