This document describes how to quickly integrate the Tencent Cloud IM SDK (iOS) to your projects. To configure and integrate the SDK, follow these steps.

Production Environment Requirements

• Xcode 9.0+.
• iPhone or iPad on iOS 8.0 or above.
• Your project has a valid developer signature.

Integrating the IM SDK

You can either automatically integrate the IM SDK using CocoaPods, or manually download the SDK and import it to your current project.

Automatic loading using CocoaPods

1. Install CocoaPods

Enter the following command in the terminal window (you need to install the Ruby environment on your macOS in advance):

sudo gem install cocoapods

2. Create a Podfile

Go to the path where the project is located and run the following command. Then, a Podfile will appear under the project path.

pod init

3. Edit the Podfile

If you are using the SDK standard edition, edit the Podfile as follows:

platform :ios, '8.0'
source 'https://github.com/CocoaPods/Specs.git'
target 'App' do
pod 'TXIMSDK_iOS'
end

If you are using the SDK lite edition, edit the Podfile as follows:

platform :ios, '8.0'
source 'https://github.com/CocoaPods/Specs.git'
target 'App' do
pod 'TXIMSDK_Smart_iOS'
end

If you are using the SDK bitcode lite edition, edit the Podfile as follows:

platform :ios, '8.0'
source 'https://github.com/CocoaPods/Specs.git'
target 'App' do
pod 'TXIMSDK_Smart_iOS_Bitcode'
end

If you are using the SDK XCFramework lite edition, edit the Podfile as follows:

platform :ios, '8.0'
source 'https://github.com/CocoaPods/Specs.git'
target 'App' do
pod 'TXIMSDK_Smart_iOS_XCFramework'
end

If you are using the SDK XCFramework lite edition (bitcode supported), edit the Podfile as follows:

platform :ios, '8.0'
source 'https://github.com/CocoaPods/Specs.git'
target 'App' do
pod 'TXIMSDK_Smart_iOS_Bitcode_XCFramework'
end

4. Update and install the SDK

Run the following command in the terminal window to update the local library file and install the TXIMSDK:

pod install

Or, run the following command to update the local repository:

pod update

After the pod command is executed, an .xcworkspace project file integrated with the SDK will be generated. Double-click this file to open it.

Note：

If the pod search fails, you are advised to update the local repo cache of the pod by running the following commands:

>pod setup
pod repo update
rm ~/Library/Caches/CocoaPods/search_index.json

Manual integration

1. Download the SDK

Download the latest SDK version from GitHub:

• ImSDK.framework and ImSDK_Smart.framework are the core dynamic library files of the IM SDK.

  Package Name	Description
  ImSDK.framework	IM SDK standard edition
  ImSDK_Smart.framework	IM SDK lite edition

• TXLiteAVSDK_UGC.framework is the Tencent Cloud UGSV SDK that implements short-video sending and receiving in IM. It is an optional component.

  Package Name	Description	Feature
  TXLiteAVSDK_UGC.framework	Extension package for recording and editing short videos	This package provides short video recording and editing features. For more information, see UGSV SDK Documentation.

2. Create a project

Create a project.

Enter a project name, for example, IMDemo.

3. Integrate the IM SDK

Add the dependency library: select Target for IMDemo. On the General panel, add the dependency library under Embedded Binaries and Linked Frameworks and Libraries. If you use the SDK standard edition, select ImSDK.framework. If you use the SDK lite edition, select ImSDK_Smart.framework.

Set link parameters: add -ObjC in **Build Setting -> Other Linker Flags.

Note：

For manual integration, you need to change ImSDK.framework to Embed&Sing in Target -> General -> Frameworks -> Libraries and Embedded Content.

Referencing the IM SDK

There are two ways to use the SDK in your project code.

Method 1

Choose Xcode -> Build Setting -> Header Search Paths, and set the SDK header file path. In files that require the SDK API, reference the corresponding header file.

• If you use the SDK Standard Edition, reference the header file as follows:

  #import "ImSDK.h"
  

• If you use the SDK Lite Edition, reference the header file as follows:

  #import "ImSDK_Smart.h"
  

Method 2

Use the following codes to import specific header files into the project's files that need to use the SDK APIs.

• If you use the SDK Standard Edition, reference the header file as follows:

  #import <ImSDK/ImSDK.h>
  

• If you use the SDK Lite Edition, reference the header file as follows:

  #import <ImSDK_Smart/ImSDK_Smart.h>
