javascript - Is there any way to use window.onbeforeunload on Mobile Safari for iOS devices?

Question

Looks like Apple has disabled the window.onbeforeunload event for iOS devices (iPhone, iPad, iPod Touch). Unfortunately I can't find any documentation as to why this event doesn't work in Mobile Safari.

Does anyone know if there's a reliable alternative to this function? Android's browser appears to support it just fine, and the Safari desktop application also supports the onbeforeunload event without issue.

I see that it's an old question, but i faced this problem recently.

I'm using window.unload and it works fine in ios browsers (although if you look at Apple documentation it seems to be deprecated and they recommend to use document.pagehide)
