This document describes how to quickly integrate RT-Cube’s MLVB LiteAVSDK for iOS into your project.

Environment Requirements

• Xcode 9.0 or above
• iPhone or iPad with iOS 9.0 or above
• A valid developer signature for your project

Integrating the SDK

You can use CocoaPods to automatically load the SDK or manually download the SDK and import it into your project.

CocoaPods

1. Install CocoaPods

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

sudo gem install cocoapods

2. Create a Podfile

Go to the directory of your project and enter the following command to create a Podfile in the directory.

pod init

3. Edit the Podfile

There are two ways to edit the Podfile:

• Method 1: use the path of the PODSPEC file of LiteAVSDK
  platform :ios, '9.0'
  
  target 'App' do
  pod 'TXLiteAVSDK_International', :podspec => 'https://liteav.sdk.qcloud.com/pod/liteavsdkspec/TXLiteAVSDK_International.podspec'
  end

• Method 2: use CocoaPod’s official source, which allows version selection

4. Update the local repository and install the SDK

Enter the following command in a terminal window to update the local repository file and install LiteAVSDK:

pod install

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

pod update

An XCWORKSPACE project file integrated with LiteAVSDK will be generated. Double-click to open the file.

Manual integration

1. Download LiteAVSDK and decompress the file.
2. Open your Xcode project, select the target you want to run, and select Build Phases.
   
3. Expand Link Binary with Libraries and click + at the bottom to add the libraries to depend on.
   
4. Add the downloaded TXLiteAVSDK_International.framework and the libraries it depends on:

   libz.tbd
   libc++.tbd
   libresolv.tbd
   libsqlite3.tbd
   Accelerate.framework
   OpenAL.framework
   

   
5. Click Build Settings, search for Other Linker Flags, and add -ObjC.
   

Granting Camera and Mic Permissions

To use the audio/video features of the SDK, you need to grant it mic and camera permissions. Add the two items below to Info.plist of your application to display pop-up messages asking for mic and camera permissions.

• Privacy - Microphone Usage Description, plus a statement specifying why mic access is needed
• Privacy - Camera Usage Description, plus a statement specifying why camera access is needed

Importing the SDK

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

• Method 1: import the SDK module in the files that need to use the SDK’s APIs in your project

  @import TXLiteAVSDK_International;
  

• Method 2: import a specific header file in the files that need to use the SDK’s APIs in your project

  #import "TXLiteAVSDK_International/TXLiteAVSDK.h"
  

Configuring License

Log in to the CSS console, go to MLVB SDK > License Management, and click Get License to obtain a trial license. For detailed directions, see Applying for trial license. You will get two strings: a license URL and a decryption key.

Before you use LiteAVSDK features in your application, complete the following configurations (preferably in - [AppDelegate application:didFinishLaunchingWithOptions:]):

@import TXLiteAVSDK_International;
@implementation AppDelegate
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
  NSString * const licenceURL = @"<The license URL obtained>";
  NSString * const licenceKey = @"<The key obtained>";

  //TXLiveBase can be found in the "TXLiveBase.h" header file
  [TXLiveBase setLicenceURL:licenceURL key:licenceKey]; 
  NSLog(@"SDK Version = %@", [TXLiveBase getSDKVersionStr]);
}
@end

FAQs

Can I run LiteAVSDK in the background?

Yes, you can. If you want the SDK to run in the background, select your project, under the Capabilities tab, set Background Modes to ON, and check Audio, AirPlay and Picture in Picture, as shown below:
