iOS Tutorial for Objective-C - 1to1

English | 中文

The Agora iOS Tutorial for Objective-C 1to1 Sample App is an open-source demo that will help you get video chat integrated directly into your iOS applications using the Agora Video SDK.

With this sample app, you can:

  • Join / leave channel
  • Mute / unmute audio
  • Enable / disable video
  • Switch camera

Problem

After users upgrade their iOS devices to iOS 14.0, and use an app that integrates the Agora RTC SDK for iOS for the first time, users see a prompt for finding local network devices. The following picture shows the pop-up prompt:

Solution

Prerequisites

  • Xcode 10.0+
  • Physical iOS device (iPhone or iPad)
  • iOS simulator is NOT supported

Quick Start

This section shows you how to prepare, build, and run the sample application.

Obtain an App ID

To build and run the sample application, get an App ID:

  1. Create a developer account at agora.io. Once you finish the signup process, you will be redirected to the Dashboard.

  2. Navigate in the Dashboard tree on the left to Projects > Project List.

  3. Save the App ID from the Dashboard for later use.

  4. Generate a temp Access Token (valid for 24 hours) from dashboard page with given channel name, save for later use.

  5. Open Agora iOS Tutorial Objective-C.xcodeproj and edit the AppID.m file. Update <#Your App Id#> with your app ID, and assign the token variable with the temp Access Token generated from dashboard.

    NSString *const appID = @"<#Your App ID#>";
// assign token to nil if you have not enabled app certificate
NSString *const token = @"<#Temp Token#>";

To ensure communication security, Agora uses tokens (dynamic keys) to authenticate users joining a channel.

Temporary tokens are for demonstration and testing purposes only and remain valid for 24 hours. In a production environment, you need to deploy your own server for generating tokens. See [Generate a Token](https://docs.agora.io/en/Interactive Broadcast/token_server)for details.

Integrate the Agora Video SDK

  1. Download the Agora Video SDK. Unzip the downloaded SDK package and copy the following files from the SDK libs folder into the sample application Agora iOS Tutorial Objective-C folder.

    • AograRtcEngineKit.framework
    • AgoraRtcCryptoLoader.framework

  2. Connect your iPhone or iPad device and run the project. Ensure a valid provisioning profile is applied or your project will not run.
