Note: this project is designed to work with the newer version of React Native library imports, i.e. React Native >= 0.40.0
$ npm install react-native-screenshot-detector --save
$ react-native link react-native-screenshot-detector
#import <RNScreenshotDetector/RNScreenshotDetector.h>
- (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];
}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);
