In this tutorial, you will learn how to create an iOS application using Objective-C and the Nexmo iOS Client SDK, and then write the code to make an app to app call.
Two parts are needed to achieve this:
- An iOS application that will make the voice call using the Client SDK.
- A publicly accessible URL that serves instructions on how to handle the call. To accomplish this, you will create a webhook server using Node.js, Express and localtunnel.
This tutorial uses NexmoClient version 3.1.0
