  • How do you call `Twilio.addEventListener`? You need to pass a function for the second argument. – Kerumen Sep 27 '16 at 08:22
  • I am not calling like this Twilio.addEventListener('deviceDidStartListening', this.deviceDidStartListening()); – Sport Sep 27 '16 at 09:03

    _Not_? If it's a typo and you are calling like this, it's wrong. You have to do `Twilio.addEventListener('deviceDidStartListening', this.deviceDidStartListening);` You must not call the function but only pass the reference. – Kerumen Sep 27 '16 at 09:12

I have fixed that issue .issue is not in twilio npm . issue about the setup iOS react native project. now i have used this steps 1-in node_modules,react-native-twilio/ios and add RCTTwilio.xcodeproj to your project.

2- Add libRCTTwilio.a to Build Phases -> Link Binary With Libraries

I have done mistake to call Twilio.addEventListener (), its need Twilio.addEventListener ('type of event', 'call a event hadler'),

for example 

Twilio.addEventListener('deviceDidReceiveIncoming', this._deviceDidReceiveIncoming);
