(Fixed) Snaps to top of screen on blur on iOS 12+

[YCMitch]

After days of screwing around with other plugins/settings/native code/angry users/bottles of wine I've discovered THIS plugin is to blame.

As of recently (I'm not sure exactly when), when you focus a text input, then un-focus it, the screen rockets up to the top. There's nothing you can do about it. I've tried:

• disableScroll(true)
• shrinkView
• automaticScrollToTopOnHiding = false
• manually getting/setting scrollTop on keyboardWillHide/keyboardDidHide
• howling at the moon

I'd nearly lost my mind until I removed this webview and used Apache's cordova-plugin-wkwebview-engine. It miraculously stopped acting like it was possessed by a demon, and all was well in the world.

Surely other people are encountering this?

I have been going down this rabbit hole myself trying to find a solution. You're seeing this behavior due to this 'fix'.

The cordova have a matching bug which has remained unresolved
apache/cordova-plugin-wkwebview-engine#71
which they tried to use the ionic fix in this pull request
apache/cordova-plugin-wkwebview-engine#75
but it was rejected because people noticed scrolling to the top is often not the intended behavior.
There are JS fixes which do similar (scroll to top)

At present it seems the only solution is to downgrade to XCode 9.

That makes so much sense, Serivy. I just moved from Ionic's WKWebview back to Apache's one cause of the abhorrent scroll-to-top thing. I thought it was just a bug.

If I downgrade to Xcode 9, wouldn't I then be unable to use iOS 12 SDK? I was considering that for ages but then read Apple won't approve any apps that don't use the iOS 12 SDK.

Yep, i'm in a similar situation (except I'm not using ionic), i don't want to down grade, and i can't switch back to the old web view (because of rendering bugs that forced us to upgrade), so all I can hope is apple fixes it soon, but doesn't look like a lot of movement given the feedback in those links to apple support.

As an update, I got a XCode 10.3 (10G8) today on my build server and fingers crossed it looks like it works (without the scroll to top fix) while deployed to test flight. That being said i found experimenting on my development xcode of 10.2.1 (10E1001) deployed to device didn't have this problem but couldn't get our build server to replicate it.

Cordova's WKWebview and Ionic keyboard with keyboardResizeMode set to body seemed to fix all my scrolling/keyboard/screen issues. It doesn't jump to the top anymore and all works fairly predictably.

It's not great at scrolling down when inputs are focused, but that's pretty easily fixed with JS.

So there is no other solution than ditching this plugin and use Cordova WKWebview instead?

[YCMitch]

In my experience, yeah. I couldn't find any way around it.

I am experiencing this issue as well, when will it be fixed?
