react-native-lightbox-v2

👀 0.8.9-beta.0 is coming!

Fork this project to do some updates, because the original library seems to be out of maintenance！ Thanks Joel Arvidsson

Installation

I changed the name in order to publish to npm, it is not actually a new version, it just fixed some problems based on the original！

yarn add react-native-lightbox-v2

Usage

Note: react-native-lightbox-v2 will no longer support navigator after version 0.8.9.

navigator property is optional but recommended on iOS, see next section for Navigator configuration.

import Lightbox from 'react-native-lightbox-v2';

const LightboxView = ({ navigator }) => (
  <Lightbox navigator={navigator}>
    <Image
      style={{ height: 300 }}
      source={{ uri: 'http://knittingisawesome.com/wp-content/uploads/2012/12/cat-wearing-a-reindeer-hat1.jpg' }}
    />
  </Lightbox>
);

can long press to save image?

longPressCallback can resolve it!

const uri = 'http://knittingisawesome.com/wp-content/uploads/2012/12/cat-wearing-a-reindeer-hat1.jpg'
const longPress = (uri) => {
  CameraRoll.saveToCameraRoll(uri)
}
<Lightbox longPressCallback={() => longPress(uri)}>
    <Image
      style={{ height: 300 }}
      source={{ uri }}
    />
  </Lightbox>

Navigator setup/Android support

Note: react-native-lightbox-v2 will no longer support navigator after version 0.8.9.

For android support you must pass a reference to a Navigator since it does not yet have the Modal component and is not on the official todo list. See the Example project for a complete example.

const renderScene = (route, navigator) => {
  const Component = route.component;

  return (
    <Component navigator={navigator} route={route} {...route.passProps} />
  );
};

const MyApp = () => (
  <Navigator
    ref="navigator"
    style={{ flex: 1 }}
    renderScene={renderScene}
    initialRoute={{
      component: LightboxView,
    }}
  />
);
