Customizing Ionic Apps for Web & Mobile

By Simon on February 12, 2018DESKTOPFRAMEWORKTUTORIALS

This is a guest post from Simon Grimm, speaker and educator at Ionic Academy. Simon writes about Ionic frequently on his blog Devdactic.

With the development of Ionic apps comes the promise that your code will run on various platforms and screen sizes once it’s ready. While this can work and look fine on your targeted devices out of the box, it might not at first for everyone.

In this post, we’ll take a look at 4 areas to keep an eye on – especially if you plan to ship your Ionic app both as a website (or perhaps PWA?) and also as a native mobile app (perhaps even on phone and tablet devices).

Everything we need is already built into Ionic, but sometimes it’s easy to forget about all the awesomeness. So let’s get started with a tiny base for our examples!

App Starting Template Setup

For this article run the command below to start a new Ionic app with the side menu template:

ionic start devdacticResponsive sideMenu

It’s a super basic app with just 2 pages and a side menu (otherwise the name would be kinda bad) but we also need to make HTTP calls, therefore we use the new HttpClient which is available since Angular 5 and Ionic 3.9.0.

Simply change your app/app.module.ts to:

import { BrowserModule } from '@angular/platform-browser'; import { ErrorHandler, NgModule } from '@angular/core'; import { IonicApp, IonicErrorHandler, IonicModule } from 'ionic-angular'; import { MyApp } from './app.component'; import { HomePage } from '../pages/home/home'; import { ListPage } from '../pages/list/list'; import { StatusBar } from '@ionic-native/status-bar'; import { SplashScreen } from '@ionic-native/splash-screen'; import { HttpClientModule } from '@angular/common/http'; @NgModule({ declarations: [ MyApp, HomePage, ListPage ], imports: [ BrowserModule, IonicModule.forRoot(MyApp), HttpClientModule ], bootstrap: [IonicApp], entryComponents: [ MyApp, HomePage, ListPage ], providers: [ StatusBar, SplashScreen, {provide: ErrorHandler, useClass: IonicErrorHandler} ] }) export class AppModule {}

That’s all we’ll need for our examples, so now let’s dive into our areas.

1. Responsive Grid Layout

Most Ionic components already adapt to screen changes and look good across various sizes. However, having something like a list item full size or an Ionic Card displayed full width on my large iMac screen kills my eyes. 

If you need your app to look good on a small device and in a desktop web browser, you’ll need to make it as responsive as possible. And what’s better then using the Ionic Grid layout system?

But first we need some data we can display inside a list, so let’s add a simple HTTP call to your pages/home/home.ts like this:

import { Component } from '@angular/core'; import { NavController } from 'ionic-angular'; import { Observable } from 'rxjs/Observable'; import { HttpClient } from '@angular/common/http'; import "rxjs/add/operator/map"; @Component({ selector: 'page-home', templateUrl: 'home.html' }) export class HomePage { users: Observable<any>; constructor(public navCtrl: NavController, private httpClient: HttpClient, private plt: Platform, private alertCtrl: AlertController) { this.users = this.httpClient.get('https://randomuser.me/api/?results=20') .map(res => res['results']) } }

Now we have an array of users from the Randomuser API which we can display as cards. You could make this as simple iteration without any further testing, but if you’re serious about your design (which, of course you are!), you’ll want to make sure to test different sizes and breakpoints.

A breakpoint is a predefined value at which your design snaps from one category to the next. If your screen is smaller than 576px, you fall into the smallest category which is xs. However, at 577px your design will get the sm category applied, so you must prepare your design to also look good there, and at later breakpoints as well.

With Ionic, we can use the row and column system plus the breakpoints to build interfaces that look great across different platforms and adapt to display the best and most intuitive interface to the user.

Let’s take our example and add this code to our pages/home/home.html:

<ion-header> <ion-navbar> <button ion-button menuToggle> <ion-icon name="menu"></ion-icon> </button> <ion-title>Home</ion-title> </ion-navbar> </ion-header> <ion-content> <ion-grid> <ion-row> <ion-col *ngFor="let user of users | async" col-12 col-xl-2 col-lg-3 col-md-4> <ion-card> <ion-item> <ion-avatar item-start> <img [src]="user.picture.medium"> </ion-avatar> <h2 text-capitalize>{{ user.name?.first }} {{ user.name?.last }}</h2> </ion-item> <ion-card-content> Bacon ipsum dolor amet salami prosciutto ham hock, strip steak buffalo ribeye pork chop. Beef ribs tenderloin tail shoulder. Spare ribs ham shoulder brisket rump hamburger. Pork belly kevin shoulder prosciutto ribeye pork chop chicken strip steak pig. </ion-card-content> </ion-card> </ion-col> </ion-row> </ion-grid> </ion-content>

One Ionic row offers 12 units space for columns, so each column can take an amount of those 12. If your row takes 12 units, it means the row is already full and the next column will be displayed in the following row.

The syntax for the column isn’t immediately obvious, so let’s dive deeper into what it actually means:

col-12: If no other rules match, the column will take all 12 units (greedy column!)col-md-4: At a minimum width of 768px, each column will only use 4 units. This means, a row can now handle 3 columnscol-lg-3: As the screen gets bigger than 992px, a column only needs 3 units which means the row how holds 4 columnscol-xl-2: On the largest screens (1200px+), a column only needs 2 units and a row will display 6 columns

In our example, a column always holds a card, so the design ranges from seeing only 1 card to 6 cards maximum (seen below).

Using a decent flexible layout is definitely mandatory if your app is going to run on multiple platforms and screen sizes. If you don’t invest time into doing this, your app might scare off potential users because it just looks odd.

There’s a lot more to the Grid like setting your own breakpoints, reordering columns, and more so go check it out!

2. CSS Media Queries

While we can’t really accredit this one directly to Ionic, we are still lucky that Ionic bets strongly on the Web and we can thus take advantage of languages like CSS, which most of us have all learned years ago.

Just like the grid layout, we can make use of breakpoints here as well by using @media and different sizes to change part of our UI.

In a recent app, we needed an ion-fabbutton at the top right corner on the web version as it was too hard to spot when it was at the far bottom right corner. However, on a mobile version of your app users are already familiar with having the button floating above lists at the bottom right.

This means the element needs exist in completely different places depending on screen size (and this is a simple element).

One way to achieve this is by having the element there twice, but only displaying it when the media query of your CSS matches. To do this, add the Fab button to your your pages/home/home.html after the list we already have:

<ion-fab right bottom class="web-fab"> <button ion-fab icon-only color="primary" (click)="checkPlatform()"> <ion-icon name="help"></ion-icon> </button> </ion-fab> <ion-fab right top edge class="mobile-fab"> <button ion-fab icon-only color="primary" (click)="checkPlatform()"> <ion-icon name="help"></ion-icon> </button> </ion-fab>

If you want to make only one button visible, you could use the follow CSS inside your pages/home/home.scss:

page-home { @media (max-width: 576px) { ion-card-content { font-size: 2rem !important; } } @media (max-width: 820px) { .mobile-fab { display: none; } } @media (min-width: 820px) { .web-fab {

고양이 셀카 찍어주는 ‘캣스냅’ 



‘캣스냅‘은 고양이 셀카를 찍을 수 있는 앱이다. 움직이는 작은 물체에 반응하는 고양이의 특성을 이용해 고양이가 스스로 스마트폰이나 태블릿을 터치해 사진을 촬영한다. 기기 화면에 빨간 점이 이리저리 움직이는데, 그 점을 고양이가 터치하는 순간 진동과 함께 사진이 ‘찰칵’ 찍히는 방식이다. 고양이에 맞춰 움직이는 빨간 점의 속도나 민감도를 조절할 수 있다.


앱을 쓸 때 주의해야 할 부분은 ‘각도’다. 고양이가 터치하기 쉬우라고 스마트폰이나 태블릿을 바닥에 놓고 촬영하면 의도치 않게 ‘굴욕샷’만 찍힐 수 있다. 스마트폰 거치대 등을 활용해 꼭 옆으로 세워두는 식으로 촬영하는 걸 추천한다.
