Weird issue with keyboard on iOS

[okonon]

Hello @devgeeks thanks for such a great plugin. We have a confirmed issue where we have an app with privacy screen plugin installed our input fields are acting up. When users tap in an input field - field receives focus but keyboard does not open. The only way to get a keyboard up is to double tap on the input field.

This is happening on multiple ios versions - 9.3 and 9.2.1

If I remove the plugin inputs in the app behave normally - user taps on an input and keyboard appears. If i add the plugin back in the issue is back.
Plugin versions that seem to cause the issue 0.1.3 and 0.1.2

Cordova CLI: 6.1.0 (cordova-lib@undefined)
cordova-ios: 4.1.0
Gulp version:  CLI version 3.9.0
Gulp local:   Local version 3.9.0
Ionic Version: 1.2.4
Ionic CLI Version: 2.0.0-beta.23
Ionic App Lib Version: 2.0.0-beta.13
ios-deploy version: 1.8.5 
ios-sim version: 4.1.1

Ok. so i think i figured why this started to happend to our apps. When i force cordova-ios to 3.9.2 version by changing line <engine name="ios" spec="~4.1.0" /> to <engine name="ios" spec="3.9.2" /> the issue goes away.

So i think this plugin is not compatable with cordova-ios 4.1.0

I can't reliably make this happen, but anecdotally I am seeing this sometimes.

Not sure what it is though :/

Just wanted to chip in I am experiencing this issue with the following dependencies:

cordova-plugin-privacyscreen 0.3.1
cordova 6.5.0
cordova-ios 4.4.0
iOS 9

Seems to be related to setting self.viewController.view.window.hidden. When I remove all other logic except the lines setting that property to No in onAppDidBecomeActive and Yes in onAppWillResignActive, the bug still persists. I'm not an iOS dev, but can't see why this line should cause any issues so perhaps it's a bug in cordova-ios.

As a workaround, I've replaced hiding the window with overlaying a simple black view (a bit like how the plugin overlays the splash screen, but that didn't seem to be working for me). Code diff here: JamesP-KC@2110f0d

It's a workaround that suits my needs (so perhaps it might be useful to others) but it doesn't really address the underlying problem so I won't open a PR.
