How it all comes together

  • Your App
  • Ionic
  • Angular
  • WebView (Cordova)
  • Native App

Collection Repeat

  • Replacement for Angular's ng-repeat
  • Inspired by iOS’s UICollectionView
  • Scroll through thousands of items
  • Only renders the viewable items
  • Smooth scrolling!
<div class="list">
  <div collection-repeat="c in contacts">
    <h2>{{ c.name }}</h2>
    <p>{{ c.email }}</p>
  </div>
</div>

Navigation

  • Uses AngularUI Router
  • Shows back button when possible
  • Transitions follow direction of nav
  • Updates the app's URL
  • Multi-history stack
<ion-tabs>

  <ion-tab title="Home" icon="ion-ios-home">
    <ion-nav-view name="home"></ion-nav-view>
  </ion-tab>

  <ion-tab title="About" icon="ion-ios-information">
    <ion-nav-view name="about"></ion-nav-view>
  </ion-tab>

  <ion-tab title="Contact" icon="ion-ios-world">
    <ion-nav-view name="contact"></ion-nav-view>
  </ion-tab>

</ion-tabs>
