Mousemove event does not work on iOS

Ionic Framework ionic-v3
1

Hey there,

I tried to apply an mousemove event listener on ion-content in an empty project. The current touch coordinate relative to the screen width should then be visible on the page itself.
It works only in Google Chrome and Safari but not in the iOS build.
I’ve tried replacing mousemove with touchmove and tap (which is the only thing that seems to work on iOS). If I don’t disable the scrolling mousemove works in a random behavior.

My Ionic version is:
“ionic-angular”: "2.2.0"
“ionic-native”: “2.4.1”

Since it is the default generated blank page project, here are only the changes I made:

home.ts
import { Component, ViewChild } from ‘@angular/core’;
import { App, Platform } from ‘ionic-angular’;

import { NavController } from 'ionic-angular';

var data = 0;

...

constructor(public navCtrl: NavController, public platform: Platform, private app: App) {
  		platform.ready().then((readySource) => {
    		this.screenX = platform.width();
    		this.screenY = platform.height();
    	});
  }

  ngAfterViewInit() {
  	this.app._setDisableScroll(true);
  }

  pressEvent(event) {
  		
  	this.data = event.clientX / this.screenX;

  }

...

home.html
<ion-content no-bounce (mousemove)=“pressEvent($event)”>

	<p>{{ data }}€</p>

</ion-content>

Thanks a lot!
