> Key: CB-12408
> URL: https://issues.apache.org/jira/browse/CB-12408
> Project: Apache Cordova
> Issue Type: Bug
> Components: cordova-plugin-wkwebview-engine
> Affects Versions: 6.4.0
> Environment: iPhone 6S Plus on device running iOS 10 only
> Reporter: Alex Fox
> Assignee: Shazron Abdullah
> Priority: Critical
> Labels: WKWebview, wkwebview-baked-in, wkwebview-known-issues
>
> I am using auto crash recovery in the WKWebViewEngine plugin and I have
> noticed that sometimes when the page enters the foreground and it reloads I
> end up with a blank screen.
> I have inspected the app with WebKit from my MacBook and I can see that there
> is a DOM. When I hover over elements with my mouse I can see the elements
> highlighting on the device. The javascript is still running and the app still
> reacts to touches.
> Refreshing the page again does not make the DOM appear and if I navigate to
> another page I still have a blank screen.
> I have managed to easily reproduce the problem with a clean project and a
> slight modification to make the app refresh every time it's brought to
> foreground. My "test" only happens on my iPhone 6S Plus. I have tried it on
> an iPhone 5 & iPad mini 2 but the bug never seems to happen.
> Here are the steps:
> - cordova create hello com.example.hello HelloWorld
> - cordova platform add ios --save
> - cordova plugin add cordova-plugin-wkwebview-engine
> - In CDVWKebViewEngine.m => method (BOOL)shouldReloadWebView) => line 185 =>
> Change it to return YES; (so it will awlays reload!)
> - Run the app on the device (remember to use an iPhone 6S Plus, though
> perhaps it would still be a problem on a similar device 6/6s/7)
> - Repeatedly send the app to the background/foreground by pressing the home
> button / app icon
> - It usually will occur in 1-5 "reloads" but sometimes it can be up to ~25
> Needless to say this is a critical error that is preventing me releasing my
> app.
