App crash[WebCore::TimerBase] on iPad only on iOS 11 #311

Open umair-citrusbits opened 6 years ago

umair-citrusbits commented 6 years ago

The app is crashing on iPad only. Doesn't know the exact reproducible steps because it occurs randomly. It looks like there is a problem with the javascript engine which causes weird crashes.

Me too,what changed by the Apple?

suzhenghao commented 6 years ago

Me too, did you solve it?

SumeetMourya commented 5 years ago

I tried with another library for this issue, it's work for me. You can try it. https://github.com/hmhv/YoutubePlayer-in-WKWebView

@SumeetMourya Thanks for the library. However, your link is broken and goes to this repository instead.

I've been experiencing tons of UIWebView related crashes since Xcode 10/iOS 12 (not just with this library), so I think it's definitely time to move fully to WKWebView.
