Integration

This article will guide you through the quick integration of the TUICallKit component. You will complete several key steps within 10 minutes, ultimately obtaining a video call feature with a complete UI interface.

Environment Preparations
Xcode 13 or later.
iOS 13.0 or later.
CocoaPods environment installation, Click to view.
If you experience any issues with access or usage, please consult the FAQs.
Step 1. Activate the service
Refer to Activate the Service to obtain SDKAppID, SDKSecretKey, which will be used as Mandatory Parameters in Step 4: Log in to the TUICallKit component.
Step 2. Import the component
Use CocoaPods to import the component. If you encounter any issues, please refer to Environment Preparation first. Detailed steps for importing the component are as follows:
1. Please add the dependency pod 'TUICallKit_Swift' to your Podfile. If you encounter any problems, please refer to the Example project.
target 'xxxx' do
  ...
  pod 'TUICallKit_Swift/Professional'
end
Note:
If your project lacks a Podfile, you need to cd into the xxxx.xcodeproj directory in Terminal, and then create a Podfile by executing the following command:
pod init
2. In Terminal, first cd into the Podfile directory and then run the following command to install components.
pod install
Note:
If you cannot install the latest version of TUICallKit, you may first delete Podfile.lock and Pods. Then run the following command to update the local CocoaPods repository list.
pod repo update
Then, run the following command to update the Pod version of the component library.
pod update
3. We suggest you compile and run once. If you encounter any problems, you can refer to our FAQs. If the problem remains unresolved, you may try running our Example project. If you encounter any issues during integration and use, you are welcome to provide feedback to us.
Step 3: Configure the Project
To use audio and video features, you need to authorize the usage of the camera and microphone. Please set the required permissions according to the actual needs of the project.
1. In Xcode, select TARGETS > Info > Custom iOS Target Properties from the menu.

﻿
﻿
2. Click the + button to add camera and microphone permissions.

Step 4: Log in to the TUICallKit component
Add the following code to your project. It works by calling the relevant interfaces in TUICore to complete the login to TUI Component. This step is very important, only after successfully logging in, you can normally use the features offered by TUICallKit.
Swift
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 with the SDKAppID obtained from the console in the step 1
    let secretKey = "****"     // Please replace with the SecretKey obtained from the console in the step 1
﻿
    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 with the SDKAppID obtained from the console in the first step
    NSString *secretKey = @"****";   // Please replace with the SecretKey obtained from the console in the first step
﻿
    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
Your own User ID based on your business. It can only include letters (a-z, A-Z), digits (0-9), underscores, and hyphens.
sdkAppID
Int32
The unique identifier SDKAppID for the audio and video application created in Tencent RTC Console.
secretKey
String
SDKSecretKey for the audio and video application created in Tencent RTC Console.
userSig
String
A security signature for user login to verify identity and prevent unauthorized access to cloud services.
Note:
Development Environment: During local development and debugging, use the local GenerateTestUserSig.genTestSig function to create a userSig. But be careful, the SDKSecretKey can be decompiled and reverse-engineered. If leaked, it could allow theft of your Tencent Cloud traffic.
Production Environment:  For project launch, use the Server-side Generation of UserSig method. 
Step Five: Make your first call
By calling the call function of TUICallKit and specifying the calls type and callee's userId, you can initiate an audio or video call.
Swift
Objective-C
import TUICallKit_Swift
import RTCRoomEngine
﻿
// Initiating a 1-to-1 audio call (assuming userId is mike)
TUICallKit.createInstance().calls(userIdList: ["mike"], callMediaType: .audio, params: nil) {
﻿
} fail: { code, message in
﻿
}
#import <TUICallKit_Swift/TUICallKit_Swift-Swift.h>
#import <RTCRoomEngine/TUICallEngine.h>
﻿
// Initiating a 1-to-1 audio call (assuming userId is mike)
[[TUICallKit createInstance] calls:@[@"mike"] callMediaType:TUICallMediaTypeAudio params:NULL succ:^{
} fail:^(int code, NSString * _Nullable errMsg) {
}];
