How to Customize Personal Info in Your iOS Calling App

After you have built your own iOS audio and video calling app, you may want to customize your personal information, such as nickname and avatar, to show your character and interests. With the TUICallKit component provided by Tencent RTC Call, you can achieve this functionality using the "setSelfInfo" interface. This tutorial blog will guide you step by step on how to call the "setSelfInfo" interface with just one line of code to customize your nickname and avatar.

Video Tutorial

Note: This blog post is an extension of the "How to Build A Video Calling App on iOS" tutorial, focusing on advanced features. If you haven't built an iOS calling application using the TUICallKit component yet, please refer to the "How to Build A Video Calling App on iOS" tutorial blog post first. Follow the instructions there to create a Call application in the TRTC console.

Step 1: Add the <Set> button.

First, we need to add a <Set> button on the page. By clicking this button, we will execute the `setSelfInfo` interface to set the avatar and nickname information, enabling interaction between the user and the application. Now, let's go back to the iOS Demo project and complete the basic UI setup:

• Set the starting position at x = 100, y = 200.
• Set the button's width to 50 and height to 20.
• Set the button's text content to "Set".
• Set the button's background color to gray.

1. let setSelfInfoBtn = {
2.     let btn = UIButton(frame: CGRect(x: 100, y: 200, width: 50, height: 20))
3.     btn.setTitle("Set", for: .normal)
4.     btn.backgroundColor = .gray
5.     return btn
6. }()

Step 2: Add button click event.

Now we need to add a click event for this button and then add the button to the view. In the event handler, we will call the `setSelfInfo` interface.

This interface has 4 parameters. The first parameter is the nickname, the second is the avatar, the third is the success callback, and the fourth is the failure callback.

1. TUICallKit.createInstance().setSelfInfo(nickname: "nickname", avatar: "profile photo URL", succ: {


2. }) { code, desc in


3. }

Here, I will use "TUICallKit" as an example. And you can use a pre-prepared online image URL as the avatar, passing it as a string. After successfully setting the information, print "setSelfInfo". If the setting fails, print the error code and error message.

• Nickname: TUICallKit.
• Avatar: Use the URL of an online image.
• Successful setting: Use the "print" function to print "setSelfInfo".
• Setting failure: Use the "print" function to print the error code and error message.

At this point, we have completed the implementation of the basic functionality.

Step 3: Run! Test the call.

Now let's run the program.

To compare the changes before and after the settings, we will use the official TUICallKit demo. After successfully logging in, make a call to it. After hanging up, click on the <Set> button to set the information successfully. Then make another call to it and observe the differences before and after the settings.

1. Make the first call after logging in.
