Yes it does.

But for that user with that device it timed out, so it is "down" for them.

Just released: Tooltips Module for Ionic Apps

Sorry to ask the question but is there any difference between a press and a click?

I always assumed that the only event on a button was a click - can a press action be called without it be followed by a click event.

Get rid of the domSanitizer stuff, that is not your problem.

You try to set image to contacts[i].photos[0].value.
Try console.log(contacts[i].photos[0].value) to see what you are sending to the browser to display.
Or console.log(obj) before you push to to the contacts array.

Firing functions on tab select?

I'm developing a simple shopping cart solution. When I add product (using Objects) into the Ionic Storage, everything works, but when I change the tab to CartPage, it doesn't fire the this.storage.get. It shows the object with the cart content only if I refresh the page.

Here's my code:

export class CartPage {
    cart: any;

    subtotal: any;
    shipping: any;
    total: any;

    constructor(public navCtrl: NavController, private storage: Storage) {
        this.storage.get('cart').then((result) => {
            if(result) {
                this.cart = result;
            }
            else {
                this.cart = {};
            }

            this.subtotal = 0;
            this.shipping = 0;
            this.total = 0;

            console.log();
        });
    }
}

The module listens to either click, OR press. Depending on how you
configure it. Press is different than click, you basically need to press
and hold for about a second for the event to fire. Click fires when you
press and release.

Got the same error when building a simple cordova sample app on XCode 7.3.1.
The error disappears if my iOS device is plugged in, otherwise I always get the same error when there is no iOS devices connected to my PC.
