Problem with viewController in IOS


I have fully functional code when i run my ionic application with

ionic lab
ionic emulate ios --prod

but the problem is when i upload it to ionic view OR
if i try to run the app with the following command

ionic emulate ios --prod -lcs // livereload server logs and console logs

Anyways i can’t seem to find the problem or a good way to debug it, here is the code that isn’t working. Basically there are 2 components talking to each other with events. The goal of the components are to have a overlay image helping the user to navigate in the app.

Component 1

import { Component } from '@angular/core';
import { NavController, Events, ViewController } from 'ionic-angular';

  selector: 'help',
  templateUrl: 'help.html'
export class HelpComponent {

  private img : any;
  private hide = true

  private helpers =  {
    "AccountPage": "/assets/helpers/mitt-konto.png",
    "PaymentPage": "/assets/helpers/betalningsinformation.png",
    "HomePage": "/assets/helpers/kommande-matcher.png",
    "GamePage": "/assets/helpers/matchdetaljer.png",
    "SupportYourTeamPage": "/assets/helpers/kop-andelar.png",
    "MyTeamsPage": "/assets/helpers/mina-lag.png",
    "CompletedMatchPage": "/assets/helpers/avslutade-matcher.png",
    "SettingsPage": "/assets/helpers/uppdatera-sidan.png"

    public viewCtrl: ViewController,
    public events : Events
  ){'showOverlay:', (name) => {
      this.img = this.helpers[name]
      this.hide = false

Component 2

import { Component, Input } from '@angular/core';
import { Events, NavController } from 'ionic-angular';

  selector: 'my-header',
  templateUrl: 'header.html'
export class HeaderComponent {
  @Input('title') title: string;
  constructor(public events: Events, public navCtrl: NavController) {}

  showHelp(){'showOverlay:'+this.navCtrl.getActive().name, this.navCtrl.getActive().name);


When you say you cannot find a good way of debugging this do you mean in terms of having the minified js code to plough through?

If so two suggestions:

  1. Don’t include --prod in your output
  2. On your showHelp() function, add in the word debugger; as the first line. If you have Safari open with the debugging tools it should stop at this point and allow you to step through.


Did you remote debug the problem on the device already? Follow these instructions here to debug the problem in Safari dev tools: Look at the console and network tabs for errors.
