Ion-input loses focus while using bluetooth keyboard - ios

Question

I am working on entering text with Hardware keyboard(Bluetooth connected) connected to iPhone(iOS 9 and iOS 10) in Ionic 3. While entering, The input is losing its focus and even if i try to enter again, It is not taking any input from keyboard. This hardware keyboard is working well in Android phone but not in iOS.
I tried upgrading/re-installing updated keyboard plugin from Cordova. But no luck with that.
The below is my Ionic Info.
cli packages: (/usr/local/lib/node_modules)
#ionic/cli-utils : 1.12.0
ionic (Ionic CLI) : 3.12.0
Global Packages:
cordova (Cordova CLI) : 6.5.0
Local Packages:
#ionic/app-scripts : 2.1.3

npm : 5.0.3

If any ideas, Please let me know. Thank you.
EDIT
I tried with downgrading Ionic from 3.12 to 2.18. Still no luck. Input field still looses focus within milliseconds.

Answer 1

Install the Keyboard plugin.
In app.components.ts 's constructor :
platform.ready().then(() => {
keyboard.hideKeyboardAccessoryBar(false);
});

Answer 2

There are couple of things that need to be verified here , issue you are facing is something that is related to the WebViews especially for the iOS , so let's start from the Keyboard, try to install the ionic-plugin-keyboard
cordova plugin add ionic-plugin-keyboard --save
if you need more events related to how you want to trigger the Keyboard events refer the official doc
i generally use the ionic-wkwebview rather than going with the in build webview of iOS which resolves most of the problem. You can install the plugin as follows:
ionic cordova plugin add cordova-plugin-ionic-webview --save
For complete installation refer the ionic-wkwebview-official doc
Even for the ionic-plugin-keyboard , there was issue with the ion-input but it was resolved and issue is not with the plugin but with the Webview,
Here is the reference to that issue which got resolved .
