this._nativeModule.addListener is not a function

[Sunjiawei58]

Dev setup:

• react-native-create-bridge version: 1.2.2
• react-native version: 0.49.3

I am using create-bridge in a:

• standalone library
• [yes ] existing React Native project

What you did:

I followed this tutorial video : https://www.youtube.com/watch?v=OrIIPNEjQfs
to create a object-c Native Module. the constant and the general method works perfectly, but

What happened:

when I receive the event in the JS side using
emitter.addListener('EXAMPLE_EVENT,({greeting}) =>{console.log(greeting)}').
It said "this._nativeModule.addListener is not a function"

Do you have any ideas on how that happens?

Thanks for any help

Are you using redux/react navigation in your application? I'm having the same problem and trying to pin down the reason.

Your generate generated a little bit different files that showed in this video.
Pay attention to a header file.
In video header file HelloWorld.h contains #import “RCTEventEmitter.h”, but your generated file doesn't.
As well definition of interface should be

@interface HelloWorldComponent : RCTEventEmitter <RCTBridgeModule>
  // Define class properties here with @property
@end

instead of

@interface HelloWorldComponent : NSObject <RCTBridgeModule>
  // Define class properties here with @property
@end
