NavigatorIOS

NavigatorIOS wraps UIKit navigation and allows you to add back-swipe functionality across your app.

Routes

A route is an object used to describe each page in the navigator. The first route is provided to NavigatorIOS as initialRoute:

render: function() {
  return (
    <NavigatorIOS
      initialRoute={{
        component: MyView,
        title: 'My View Title',
        passProps: { myProp: 'foo' },
      }}
    />
  );
},

Now MyView will be rendered by the navigator. It will receive the route object in the route prop, a navigator, and all of the props specified in passProps.

See the initialRoute propType for a complete definition of a route.

Navigator

A navigator is an object of navigation functions that a view can call. It is passed as a prop to any component rendered by NavigatorIOS.

var MyView = React.createClass({
  _handleBackButtonPress: function() {
    this.props.navigator.pop();
  },
  _handleNextButtonPress: function() {
    this.props.navigator.push(nextRoute);
  },
  ...
});

A navigation object contains the following functions:

• push(route) - Navigate forward to a new route
• pop() - Go back one page
• popN(n) - Go back N pages at once. When N=1, behavior matches pop()
• replace(route) - Replace the route for the current page and immediately load the view for the new route
• replacePrevious(route) - Replace the route/view for the previous page
• replacePreviousAndPop(route) - Replaces the previous route/view and transitions back to it
• resetTo(route) - Replaces the top item and popToTop
• popToRoute(route) - Go back to the item for a particular route object
• popToTop() - Go back to the top item

Navigator functions are also available on the NavigatorIOS component:

var MyView = React.createClass({
  _handleNavigationRequest: function() {
    this.refs.nav.push(otherRoute);
  },
  render: () => (
    <NavigatorIOS
      ref="nav"
      initialRoute={...}
    />
  ),
});

---
