This document describes how to rapidly integrate the TUICallKit component. You can complete the following key steps within 10 minutes and obtain a complete audio and video call interface.
﻿
Preparations
Environment Requirements
iOS system version requirements:iOS 13.0 and above.
Development tool version requirements:Xcode 13.0 and above,Xcode 15 and above may encounter Sandbox errors. Please refer to [Sandbox Issue Solutions] for fixes.
Dependency management tool requirements:CocoaPods environment setup
Device requirements: Apple mobile devices such as iPhone and iPad with iOS 13.0 or later (ensure the app can be properly installed and run).
Service Activation
Please refer to the Service Activation documentation to obtain your SDKAppID and SDKSecretKey. These credentials will be required in the subsequent Login steps.
Implementation
Step 1.Importing Components
1. Add Pod dependency:
If the project has an existing Podfile file.
Add the pod 'TUICallKit_Swift' dependency in your project's Podfile file. For example:
  target 'YourProjectTarget' do  
    pod 'TUICallKit_Swift'
﻿
  end
If the project has no Podfile file.
Enter your .xcodeproj directory in the terminal, then execute the pod init command to create a Podfile file. After creation, add the pod 'TUICallKit_Swift' dependency in your Podfile file. For example:
// 1
cd /Users/yourusername/Projects/YourProject
﻿
// 2
pod init
﻿
// 3 In the generated Podfile file
  target 'YourProjectTarget' do  
    pod 'TUICallKit_Swift'
﻿
  end
2. Install components:
Enter the directory where the Podfile file is located in the terminal, then run the following command to install components.
pod update
Step 2.Project Configuration
To ensure the audio and video features function correctly, your application needs to request access to the microphone and camera. Please add the following two privacy usage descriptions to your project's Info.plist file，these descriptions will be displayed to the user when the system initially prompts for permission.
<key>NSCameraUsageDescription</key>
<string>TUICallKitApp needs access to your camera, and it can be used for functions such as Video Call, Group Video Call.</string>
<key>NSMicrophoneUsageDescription</key>
<string>TUICallKitApp needs access to your microphone，and it can be used for functions such as Audio Call, Group Audio Call, Video Call, Group Video Call.</string>
﻿
Step 3.Login
Add the following code in your project. It enables logging in to the TUI component by calling relevant APIs in TUICore. This step is critical. Only after logging in successfully can you use the features provided by TUICallKit properly.
login
iOS (Swift)
iOS (Objective-C)
import TUICore
import TUICallKit_Swift
﻿
﻿
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
        
    let userID = "denny"       // Please replace with your UserId
    let sdkAppID: Int32 = 0    // Please replace it with the SDKAppID obtained from the console.
    let secretKey = "****"     // Please replace it with the SecretKey obtained from the console.
﻿
﻿
    let userSig = GenerateTestUserSig.genTestUserSig(userID: userID, sdkAppID: sdkAppID, secretKey: secretKey)
﻿
﻿
    TUILogin.login(sdkAppID, userID: userID, userSig: userSig) {
      print("login success")
    } fail: { code, message in
      print("login failed, code: \\(code), error: \\(message ?? "nil")")
    }
﻿
﻿
    return true
}
#import <TUICore/TUILogin.h>
#import <TUICallKit_Swift/TUICallKit_Swift-Swift.h>
﻿
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    
    NSString *userID = @"denny";     // Please replace with your UserID
    int sdkAppID = 0;                // Please replace it with the SDKAppID obtained from the console.
    NSString *secretKey = @"****";   // Please replace it with the SecretKey obtained from the console.
﻿
﻿
    NSString *userSig = [GenerateTestUserSig genTestUserSigWithUserID:userID sdkAppID:sdkAppID secretKey:secretKey];
﻿
﻿
    [TUILogin login:sdkAppID
             userID:userID
            userSig:userSig
               succ:^{
        NSLog(@"login success");
    } fail:^(int code, NSString * _Nullable msg) {
        NSLog(@"login failed, code: %d, error: %@", code, msg);
    }];
    
    return YES;
}
Parameter
Type
Description
userId
String
only allow a combination of uppercase and lowercase letters (a-z A-Z), numbers (0-9), underline and hyphen
sdkAppId
int
The unique ID assigned to your application when you Tencent Real-Time Communication (TRTC) Console.
secretKey
String
The SDKSecretKey of the audio and video application created in the Tencent Real-Time Communication (TRTC) Console.
userSig
String
A security signature used for user login authentication, confirming user authenticity and preventing malicious attacks from stealing your cloud service usage rights.
Note:
Development environment: If you are in the local development and debugging stage, you can adopt the local GenerateTestUserSig.genTestSig function to generate userSig. In this method, the secretKey is very easy to decompile and reverse. Once your key is leaked, attackers can steal your Tencent Cloud traffic.
Production environment: If your project is ready to go live, implement server-side generation of UserSig via the server.
Step 4.Set Nickname and Avatar  [Optional]
After a successful login, you can call the setSelfInfo function to set your nickname and avatar. The set nickname and avatar will be displayed on the caller/callee interface.
setSelfInfo
iOS (Swift)
iOS (Objective-C)
import TUICallKit_Swift
﻿
TUICallKit.createInstance().setSelfInfo(nickname: "jack", avatar: "https:/****/user_avatar.png") {
} fail: { code, message in
}
#import <TUICore/TUILogin.h>
#import <TUICallKit_Swift/TUICallKit_Swift-Swift.h>
﻿
NSString *nickname = @"jack";
NSString *avatar = @"https:/****/user_avatar.png";
[[TUICallKit createInstance] setSelfInfo:nickname avatar:avatar callback:nil];
Parameter
Type
Description
nickname
String
Target user's nickname
avatar
String
Target user's avatar
Step 5.Initiating a Call
The caller initiates a call by invoking the calls function and specifying the media type (voice or video) and the callee's User ID list (userIdList). The calls interface supports both one-to-one and group calls. A one-to-one call is initiated when the userIDList contains only a single User ID; a group call is initiated when it contains multiple User IDs.
Note: The calls interface cannot be written in the viewDidLoad method; it should be called in the button's click event or other user interaction response methods.
calls
iOS (Swift)
iOS (Objective-C)
import TUICallKit_Swift
﻿
// Trigger single-person voice call
TUICallKit.createInstance().calls(userIdList: ["mike"], callMediaType: .audio, params: nil) {
} fail: { code, message in
}
#import <TUICallKit_Swift/TUICallKit_Swift-Swift.h>
#import <RTCRoomEngine/TUICallEngine.h>
﻿
[[TUICallKit createInstance] calls:@[@"mike"] callMediaType:TUICallMediaTypeAudio params:NULL succ:^{
} fail:^(int code, NSString * _Nullable errMsg) {
}];
Parameter
Type
Description
userIdList
[String]
Target user ID list
mediaType
﻿TUICallMediaType﻿
Media type of the call, such as video call, voice call
params
﻿TUICallParams﻿
Call extension parameters, such as room number, call invitation timeout, offline push custom content
Step 6.Answering a Call
Once the callee successfully logs in, the caller can initiate a call, and the callee will receive the call invitation, accompanied by a ringtone and vibration.
More Features
Enabling Floating Window
You can enable/disable the floating window feature by calling enableFloatWindow. This feature should be enabled when initializing the TUICallKit component, with the default status being Off (false).
﻿
enableFloatWindow
iOS (Swift)
iOS (Objective-C)
import TUICallKit_Swift
﻿
TUICallKit.createInstance().enableFloatWindow(enable: true)
[[TUICallKit createInstance] enableFloatWindow:YES];
Details: false by default, the floating window button in the top-left corner of the call interface is hidden. Set to true to display the button and enable the feature.
Enabling Banner
You can enable or disable the incoming call banner functionality by calling the enableIncomingBanner API: by default (disabled), the callee will immediately display the full-screen call interface upon receiving an invitation, while enabling it will show a notification banner first, followed by launching the full-screen call interface as required.
﻿
enbalecomingBanner
iOS (Swift)
iOS (Objective-C)
import TUICallKit_Swift
﻿
TUICallKit.createInstance().enableIncomingBanner(enable: true)
[[TUICallKit createInstance] enableIncomingBanner:YES];
Details: Default false. When the callee receives an invitation, the full-screen call waiting interface pops up by default. When enabled, a banner is shown first, then the full-screen call interface is pulled up as needed.
Multi-Person Calling
When the caller uses the calls method to initiate a call, if the list of called users exceeds one person, it is automatically recognized as a multi-person call. Other members can then join this multi-person call using the join method.
Initiating a Multi-person Call: When the calls method is used to initiate a call, if the callee User ID list (userIdList) contains more than one user, it will be automatically deemed a multi-person call.
calls
iOS (Swift)
iOS (Objective-C)
import TUICallKit_Swift
﻿
TUICallKit.createInstance().calls(userIdList: ["mike", "tate"], callMediaType: .audio, params: nil) {
} fail: { code, message in
}
#import <TUICallKit_Swift/TUICallKit_Swift-Swift.h>
#import <RTCRoomEngine/TUICallEngine.h>
﻿
[[TUICallKit createInstance] calls:@[@"mike", @"tate"] callMediaType:TUICallMediaTypeAudio params:NULL succ:^{
} fail:^(int code, NSString * _Nullable errMsg) {
}];
Parameter
Type
Description
userIdList
[String]
Target user ID list
mediaType
﻿TUICallMediaType﻿
Media type of the call, such as video call, voice call
params
﻿TUICallParams﻿
Call extension parameters, such as room number, call invitation timeout, offline push custom content
Joining a Multi-person Call: You can use the join method to enter the specified multi-person call.
join
iOS (Swift)
iOS (Objective-C)
import TUICallKit_Swift
﻿
TUICallKit.createInstance().join(callId: "")
[[TUICallKit createInstance] joinWithCallId: @"***"];
Parameter
Type
Description
callId
String
The unique ID for this call.
Language Settings
Supported Languages: We currently support Simplified Chinese, Traditional Chinese, English, Japanese, and Arabic.
Switching Languages: By default, the language of TUICallKit is consistent with the mobile operating system's language setting. To switch the language, you can use the TUIGlobalization.setPreferredLanguage method.
setLanguage
iOS (Swift)
import TUICore
﻿
func steLanguage() {
    TUIGlobalization.setPreferredLanguage("en")
}
Parameter
Type
Description
language
String
"zh-Hans": Simplified Chinese.
"zh-Hant": Traditional Chinese.
"en": English.
"ar" : Arabic.
Note：
If you need to set up other languages, please contact us at info_rtc@tencent.com for assistance.
Ringtone Setting
You can configure the default ringtone, incoming call silent mode, and offline push ringtone using the following methods:
Method 1: If you include the TUICallKit component via source code, you can set the default ringtone by replacing the corresponding resource files (the ringtone played when initiating a call and the ringtone played when receiving a call) .
Method 2: Use the setCallingBell interface to set the incoming call ringtone received by the callee.
setCallingBell
iOS (Swift)
iOS (Objective-C)
import TUICallKit_Swift
﻿
TUICallKit.createInstance().setCallingBell(filePath: "***/callingBell.mp3")
[[TUICallKit createInstance] setCallingBell:@"***/callingBell.mp3"];
Details: Only local file paths can be imported here. You must ensure that the file directory is accessible to the application. The ringtone setting is bound to the device; therefore, replacing the user will not affect the ringtone. To restore the default ringtone, simply pass an empty filePath.
Parameter
Type
Description
filePath
String
Ringtone file path
Incoming call silent mode: You can set mute mode through enableMuteMode.
enableMuteMode
iOS (Swift)
iOS (Objective-C)
import TUICallKit_Swift
﻿
TUICallKit.createInstance().enableMuteMode(enable: true)
[TUICallKit createInstance] enableMuteMode: YES];
Details: When turned on, incoming call requests will not trigger ring.
Custom offline push ringtone:

    pushInfo.AndroidHuaWeiCategory = @"IM";
    return pushInfo;
}
Details: VoIP push does not support custom push ringtones. APNs push allows setting the iOSSound field in the offlinePushInfo of params when calling the call interface during a phone call. iOSSound should be passed with the audio filename.
Note:
Offline Push Sound settings (only applicable to iOS). To customize iOSSound, first link the voice file to the Xcode project, then set the audio filename (with extension) to iOSSound.
Ringtone duration should be less than 30s.

FAQs
Due to business needs, we need the TUICallKit source code. However, every time we update the pod, it's overwritten, resulting in loss. How can we fix this?
1. You can fork the TUICallKit repository to your GitHub/Gitee account.
2. Reference it in your project using the local pod method. The sample code is as follows:
﻿
pod 'TUICallKit_Swift', :path=>"your TUICallKit_Swift.podspec path"
Does TUICallKit support running in the background?
Yes, if you need relevant functions to continue running when the application enters the background, select the current engineering project, go to the Capabilities tab, and under the Background Modes section, check Audio, AirPlay, and Picture in Picture, as shown below:
