# react-native-lightbox-v2

👀 0.9.0 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！*

```shell
yarn add react-native-lightbox-v2
```

## Usage

> Note: react-native-lightbox-v2 will no longer support navigator after version 0.9.0.

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

```js
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!

```js
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 0.9.0.

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.

```js
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,
    }}
  />
);
```
