# react-native-screenshot-detector

Note: this project is designed to work with the newer version of React Native library imports, i.e. React Native >= 0.40.0

## Getting started

`$ npm install react-native-screenshot-detector --save`

`$ react-native link react-native-screenshot-detector`

## Usage

# iOS

```objectivec

#import 

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions

{

  // ... setup code

  // Somewhere React Native will have placed something like

  RCTRootView *rootView = [[RCTRootView alloc] initWithBundleURL...]

  // Somewhere below this you can setup the screenshot detector to listen for events

  RNScreenshotDetector* screenshotDetector = [[RNScreenshotDetector alloc] init];

  [screenshotDetector setupAndListen:rootView.bridge];

}

```

# In JS

```javascript

import * as ScreenshotDetector from 'react-native-screenshot-detector';

// Subscribe callback to screenshots:

this.eventEmitter = ScreenshotDetector.subscribe(function() { ... });

// Unsubscribe later (a good place would be componentWillUnmount)

ScreenshotDetector.unsubscribe(this.eventEmitter);

```
