javascript - WKWebView video pausing not working for all the websites -

i loading website contains videos. using wkwebview loading these videos. need stop videos autoplay when loading pages, added following java script code pause video.

nsstring *script = @"var videos = document.queryselectorall(\"video\"); (var = videos.length - 1; >= 0; i--) { videos[i].pause(); };";     [webview evaluatejavascript:script completionhandler:^(id result, nserror *error) {         nslog(@"error : %@",error.localizeddescription);         nslog(@"java script result = %@",result); }]; 

i can able pause video in of websites listing cnn, youtube etc. not working websites. example :

theglobe&mail - http://www.theglobeandmail.com/news/news-video/

bbc - http://www.bbc.com/news/video_and_audio

is there solution issue?

there property in ios 9.0 wkwebview called requiresuseractionformediaplayback if set true, autoplay should turned off

if using < ios 9.0, set property mediaplaybackrequiresuseraction true turn off autoplay.

i didnt yet try on websites mentioned. update answer once do
