Navigation and back menus
Ionic Framework has strong navigation support in the form of various directives such as ionNavView
, ionView
, ionNavBar
, and so on. Ionic stores and maintains the navigation history in the mobile app. It dictates the transitions appropriately. An app section can have multiple views, which maintain separate navigation histories.
The UI Router module and states are an integral part of the design for the navigation concepts. The <ion-nav-view>
directive has already been explained in the first section while defining the UI Router module.
<ion-view>
is another directive that should be used as a container for the content of any view. It should have a <ion-content>
directive and can have header and navbar information. It defines the title of the parent ionNavBar
using the view-title
attribute. There are other attributes such as cache-view
to enable caching, hide-back-button
to define whether the back button should be displayed or not, and hide-nav-bar
attribute to define whether to hide the parent ionNavBar
or not:
<ion-nav-bar>
is another directive that is created along with the<ion-nav-view>
directive and shows a top bar that will be modified as soon as the state changes. We can add a back button to be shown using a<ion-nav-back-button>
directive. We can also add some custom buttons using the<ion-nav-buttons>
directive.<ion-nav-title>
is a directive that can be used inside the<ion-nav-view>
directive to override the title set in the navbar with any custom title or HTML content as a title.
