Issue with iOS 11: Keyboard covering a selected text input in Ionic

Problem

Encountering an issue where the keyboard overlaps the text input in a modal when clicked. This problem was identified while testing on an iPhone SE (iOS 11) device.

After researching multiple threads, it seems that Ionic developers have been facing this persistent issue for a while now.

Here are some relevant links related to the problem: Despite trying solutions provided in the following links, none of them seem to work with my code.

Ionic 2 On-Screen Keyboard Covers Focused Input Element Inside Grid Component

Version Information

cli packages: (/usr/local/lib/node_modules)

@ionic/cli-utils  : 1.19.0
ionic (Ionic CLI) : 3.19.0

global packages:

cordova (Cordova CLI) : 7.1.0

local packages:

@ionic/app-scripts : 3.1.4
Cordova Platforms  : android 6.3.0 ios 4.5.4
Ionic Framework    : ionic-angular 3.9.2

System:

ios-deploy : 1.9.2
Node       : v8.9.0
npm        : 5.5.1
OS         : macOS High Sierra
Xcode      : Xcode 9.2 Build version 9C40b

Expected Outcome

The Ion input should remain positioned just above the keyboard as the user types messages.

Current Behavior

app.component.ts

To avoid navbar crashing issues, keyboard.disableScroll(true); has been implemented within platform.ready(). However, without this line of code, the keyboard functions properly but shifts the entire content upwards including the navbar, causing initial messages to be hidden.

Any suggestions?

UPDATE

Although unsure if my solution is optimal, currently, I've adjusted the margins of the content and footer by considering the initial height of the text area and the keyboard height combined.

If you have a better resolution, feel free to share it as an answer.

Here's the final outcome:

In a project with a setup similar to mine, I encountered issues where the iOS keyboard was overlapping the footer bar in Ionic. To fix this issue, I removed

and added

. Check out the plugin website for more information: https://github.com/ionic-team/cordova-plugin-ionic-keyboard.

It turns out that I missed the fact that ionic-plugin-keyboard was deprecated while upgrading from Ionic 1 to 2. Perhaps you were facing a similar situation.

In order to trigger actions, the first step is to determine the height of three specific elements by referring to the provided code example. For instance,

@ViewChild(Content) content: Content;

ionViewDidLoad() {
  if (this.platform.is('ios'))
    this.addKeyboardListeners();

  this.scrollContentElement = this.content.getScrollElement();
  this.footerElement = document.getElementsByTagName('your page component')[0].getElementsByTagName('ion-footer')[0];
  this.inputElement = document.getElementsByTagName('your page component')[0].getElementsByTagName('textarea')[0];
}

Subsequently, establish a keyboard listener tailored for ios platform.

addKeyboardListeners() {
  this.keyboardHideSub = this.keyboard.onKeyboardHide().subscribe(() => {
    let marginBottom = this.textareaHeight - this.initialTextAreaHeight + 44;
    this.renderer.setElementStyle(this.scrollContentElement, 'marginBottom', marginBottom + 'px');
    this.renderer.setElementStyle(this.footerElement, 'marginBottom', '0px')
  });

  this.keybaordShowSub = this.keyboard.onKeyboardShow().subscribe((e) => {
    let newHeight = (e['keyboardHeight']) + this.textareaHeight - this.initialTextAreaHeight;
    let marginBottom = newHeight + 44 + 'px';
    this.renderer.setElementStyle(this.scrollContentElement, 'marginBottom', marginBottom);
    this.renderer.setElementStyle(this.footerElement, 'marginBottom', e['keyboardHeight'] + 'px');
    this.updateScroll(250);
  });
}

Lastly, ensure that you properly unsubscribe from the keyboard listeners before leaving the current page. Create a method specifically for this purpose and invoke it as required.

removeKeyboardListeners() {
  this.keyboardHideSub.unsubscribe();
  this.keybaordShowSub.unsubscribe();
}

@coderroggie's solution was a game-changer for me!

All I had to do was uninstall ionic-plugin-keyboard and then install cordova-plugin-ionic-keyboard - problem solved!

I was dealing with two issues: - In the Chat List, the keyboard would push everything up when I focused on the input (including the navbar).

In the Search feature with a top search bar and autocomplete list, the keyboard would overlap the list when the search bar was in focus.

Hats off to @coderroggie for saving the day!

It seems like the issue at hand is related to framework compatibility. I encountered a similar problem on Android and resolved it by utilizing a keyboard plugin along with its functions to manage the viewport height. Here is the code snippet-

constructor(
    private platform: Platform,
    private keyboard: Keyboard
  ) {
    if(this.platform.is('android')){
      this.keyboard.onKeyboardShow().subscribe((e) => {
        var keyboardHeight = e.keyboardHeight;
        if ($("html").hasClass("plt-android")) {
          keyboardHeight = keyboardHeight ? keyboardHeight : '337';
          ****337 is default height to handle if keyboard height not available****
              $('body').css('height', 'calc(100vh - ' + keyboardHeight + 'px)' );
            }
          });

          this.keyboard.onKeyboardHide().subscribe(e => {
            $('input, textarea').blur();
            if ($("html").hasClass("plt-android")) {
                $("body").css("height", "100vh");
            }
          });
    }
}

required libraries--

npm install jquery
npm install @types/jquery
ionic cordova plugin add cordova-plugin-ionic-keyboard
npm install @ionic-native/keyboard

imports--

import { Platform } from '@ionic/angular';
import * as $ from "jquery";
import { Keyboard } from '@ionic-native/keyboard/ngx';

My transformation is complete!

<ion-input type="tel" pattern="tel" autocomplete="tel (ionChange)="writeValue($event.target.value)"></ion-input>

has been upgraded to

<input type="tel" (change)="writeValue($event.target.value)" autocomplete="tel">

Additionally, I've infused it with some fresh styles.

 input {
    width: 100%;
    background-color: transparent;
    border: none;
    font-size: 17px;
    font-weight: 400;
  }
  input:focus {
    outline: none;
  }
