Hi
I am using it for local notification on my ios device. In Android device working fine but in ios giving me error of "Native module cannot be null"

This issue already exists: #501 #279
In you folder ios find the proyect .xcworkspace and delete. Build your .xcodeproj
Fixed it by manual link. React-native link only able to link in android not for iOS you have to manually link this for ios.
Working fine for me after manual link
Linking manually for iOS solved the issue for me as well. It's fairly easy, but the documentation has to explicitly mention this manual need, as the node-modules folder only has an Android folder and nothing for iOS and also when you run react-native link it confirms linking for Android only.
if it helps someone.
Manual link the library in
node_modules/react-native/libraries/PushNotificationIOS/RCTPushNotification.xcodeproj for ios
https://facebook.github.io/react-native/docs/linking-libraries-ios#manual-linking
thats where the manual linking refers to. not react-native-push-notification
