Building a 1v1 Video Chat App

If you want to build a 1v1 video call similar to Omegle on your iPhone and want to have a private video or voice call with another person who has the same app installed, this tutorial shows you how to achieve this effect with only 3 lines of code. This app has a complete UI with Mic on/off, Camera on/off, Switch to audio, Cancel/Hang up, Front/Rear camera switch, and Speaker on/off functions.

Environment preparations

Xcode 13 or later.

Two iOS 13.0 or later devices.

Step 1: Download the Demo

1. Download the TUICallKit Demo source code from GitHub, or directly run the following command in the command line:

git clone https://github.com/Tencent-RTC/TUICallKit.git

2. Enter the iOS project directory in the command line:

cd TUICallKit/iOS/Example

3. Load the dependency library:

pod install

Note:

If you haven't installed CocoaPods, you can refer to this for instructions on how to install.

Step 2: Configure the Demo

1. Activate the audio and video services, to obtain the SDKAppID and SDKSecretKey.

2. Open the /iOS/Example/Debug/GenerateTestUserSig.swift file and enter the SDKAppID and SDKSecretKey obtained when activating the service:

Step 3: Running the Demo

1. In XCode, select the device you want to run the Demo on as shown below:

2. After selection, click run to deploy our TUICallKit iOS Demo to the target device.

Make the first call

Note:

To experience the complete audio and video calling process, please log into the Demo on two devices as two different users, with one acting as the caller and the other as the callee.

1. Log in & Signup

Please enter the ID at the User ID. If your current User ID has not been used before, you will be taken to the Signup screen, where you can set your own avatar and nickname.

Note:

Try to avoid setting your User ID to simple strings like "1", "123", "111", as TRTC does not support the same User ID being logged into from multiple devices. Such User IDs like "1", "123", "111" are easily occupied by your colleagues during collaborative development, leading to login failures. Therefore, we recommend setting highly recognizable User IDs while debugging.

2. Make a phone call

2.1 The caller should click 1V1 Call on the interface, enter the callee's User ID in the pop-up interface, and select the desired call type.

2.2 Click Initiate Call.

Conclusion

In conclusion, 1v1 video chat is a powerful tool that opens up new possibilities for online communication. With a focus on safety and privacy, this platform builds user confidence. Understanding its workings and benefits allows you to use it effectively, pushing the boundaries of conventional communication for web, iOS, and Android. Elevate your digital interactions today!
