Setup

Follow the instructions below to ensure that QuickBlox iOS SDK runs smoothly with your app.

Visit our Key Concepts page to get an overall understanding of the most important QuickBlox concepts.

​

Get application credentials

QuickBlox application includes everything that brings messaging right into your application - chat, video calling, users, push notifications, etc. To create a QuickBlox application, follow the steps below:

1. Register a new account following this link. Type in your email and password to sign in. You can also sign in with your Google or Github accounts.
2. Create the app clicking New app button.
3. Configure the app. Type in the information about your organization into corresponding fields and click Add button.
4. Go to Dashboard => YOUR_APP => Overview section and copy your Application ID, Authorization Key, Authorization Secret, and Account Key .

​

Requirements

The minimum requirements for QuickBlox iOS SDK are:

• iOS 12.0
• CocoaPods 1.1
• Xcode 11

​

Install QuickBlox SDK into your app

You can install the QuickBlox iOS SDK using either SPM (Swift Package Manager) or CocoaPods.

​

Swift Package Manager

To add QuickBlox IOS SDK to your project using SPM, you can follow these steps:

1. Open your Xcode project and navigate to File > Swift Packages > Add Package Dependency.
2. In the search bar, enter the QuickBlox repository URL: https://github.com/QuickBlox/ios-quickblox-sdk.git or QuickbloxWebRTC repository URL: https://github.com/QuickBlox/ios-quickblox-sdk-webrtc.git and click Add Package.
3. Xcode will then fetch the SDK and you can add it to your project by clicking Add Package.
4. You can then import QuickBlox modules into your code and use its API.

import Quickblox
import QuickbloxWebRTC

For more information on spm customization options, you can refer to the Apple Documentation.

​

CocoaPods

1. Create a Podfile. Project dependencies should be managed by CocoaPods. Create this file in the same directory with your project.

pod init
touch Podfile
open -e Podfile

1. Open the created Podfile and enter the following code lines into it.

platform :ios, "12.0"
use_frameworks!
target 'MyApp' do
    pod 'QuickBlox', '~> 2.17.10'
    pod 'Quickblox-WebRTC', '~> 2.7.6'
end

1. Install QuickBlox dependencies in your project.

pod install

1. Import headers to start using QuickBlox frameworks.

import Quickblox
import QuickbloxWebRTC

​

Run script phase for archiving

Add a Run Script Phase to build phases of your project. Paste the following snippet into the script.

bash "${BUILT_PRODUCTS_DIR}/${FRAMEWORKS_FOLDER_PATH}/QuickbloxWebRTC.framework/strip-framework.sh"

This fixes the known Apple bug that does not allow to publish archives to the App store with dynamic frameworks that contain simulator platforms. Script is designed to work only for archiving.

​

Add permissions

You can use our SDK in the background mode as well. If you want to receive push notifications when the app goes to background mode, this requires you to add specific app permissions. Under the app build settings, open the Capabilities tab and turn on Remote notifications checkbox only.

If you want to use video calling functionality in the background mode, set the Audio, AirPlay, and Picture in Picture checkboxes.

​

Initialize QuickBlox SDK

Initialize the framework with your application credentials. Pass Application ID, Authorization Key and Authorization Secret via AppDelegate file located in the root directory of your project.

Quickblox.initWithApplicationId(92, authKey: "wJHdOcQSxXQGWx5", authSecret: "BTFsj7Rtt27DAmT", accountKey: "7yvNe17TnjNUqDoPwfqp")

​

Initialize QuickBlox SDK without Authorization Key and Secret

You may don’t want to store authKey and authSecret inside an application for security reasons. In such case, you can initialize QuickBlox SDK with applicationId and accountKey only, and store your authKey and authSecret on your backend. But, if so, the implementation of authentication with QuickBlox should be also moved to your backend.

Quickblox.initWithApplicationId(92, accountKey: "7yvNe17TnjNUqDoPwfqp")

Then using your backend you can authorize a user in the QuickBlox system, send back the user session token, and set it to the QuickBlox SDK using startSession(withToken:) method. You can find out more about this in the Set existing session section.

​

Point SDK to enterprise server

To point QuickBlox SDK to the QuickBlox enterprise server, you should specify apiEndpoint and chatEndpoint in the AppDelegate file located in the root directory of your project.

Quickblox.initWithApplicationId(92, authKey: "wJHdOcQSxXQGWx5", authSecret: "BTFsj7Rtt27DAmT", accountKey: "7yvNe17TnjNUqDoPwfqp")

QBSettings.apiEndpoint = "https://yourApi.quickblox.com"
QBSettings.chatEndpoint = "yourChat.quickblox.com"

​

Selection of the hashing algorithm

You can select a hash algorithm using QBSettings.hashAlgorithm, which supports SHA1 and SHA256 options starting from version 2.19.0. QBHashAlgorithmSHA1 is set as the default option.

QBSettings.hashAlgorithm = .SHA256

​

Enable logging

Logging functionality allows you to keep track of all events and activities while running your app. As a result, you can monitor the operation of the SDK and improve the debug efficiency. There are 3 logging use cases:

• Server API logging is used to monitor Server API calls.
• Chat logging is used to monitor chat issues.
• WebRTC logging is used to gather issues with video.

Server API logging

Enable Server API calls debug console output using the setLogLevel() method.

QBSettings.setLogLevel(QBLogLevel.debug)

A log level determines what information is written to the log. There can be set the following log levels:

Chat logging

Enable a detailed XMPP logging in the console output using the code snippet below.

QBSettings.enableXMPPLogging()

Disable XMPP logging using the code snippet below.

QBSettings.disableXMPPLogging()

WebRTC logging

Set WebRTC logs using the setLogLevel() method.

SwiftObjective-C

QBRTCConfig.setLogLevel(QBRTCLogLevel.verboseWithWebRTC)

​

Enable auto-reconnect to Chat

QuickBlox Chat runs over XMPP protocol. To receive messages in a real-time mode, the application should be connected to the Chat over XMPP protocol. To enable auto-reconnect to Chat, pass autoReconnectEnabled() as true.

QBSettings.autoReconnectEnabled = true

​

Message carbons

Message carbons functionality allows for multi-device support. Thus, all user messages get copied to all their devices so they could keep up with the current state of the conversation. For example, a User A has phone running conversations and desktop running conversations. User B has desktop running conversations. When User B sends a message to User A, the message shows on both the desktop and phone of User A.

Enable message carbons

QBSettings.carbonsEnabled = true

Disable message carbons

QBSettings.carbonsEnabled = false

​

Stream management

Stream management has two important features Stanza Acknowledgements and Stream Resumption:

• Stanza Acknowledgements is the ability to know if a stanza or series of stanzas has been received by one’s peer. In other words, a reply is requested on every sent message. If the reply is received, the message is considered as delivered.
• Stream Resumption is the ability to quickly resume a stream that has been terminated. So once a connection is re-established, Stream Resumption is executed. By matching the sequence numbers assigned to each Stanza Acknowledgement a server and client can verify which messages are missing and request to resend missing messages.

Set message timeout to enable stream resumption. The preferred resumption time should be set in seconds. If this parameter is greater than 0, then it is applied, otherwise, it is not applied.

QBSettings.streamManagementSendMessageTimeout = 0

​

Custom ICE servers

You can customize a list of ICE servers. By default, WebRTC module will use internal ICE servers that are usually enough, but you can always set your own. WebRTC engine will choose the TURN relay with the lowest round-trip time. Thus, setting multiple TURN servers allows your application to scale-up in terms of bandwidth and number of users. Set up ICE servers in application(_:didFinishLaunchingWithOptions:) method of AppDelegate.m.

let username = "login"
let password = "767565gfh865486h548k6586h5868"

let urls = [
    "stun:turn.randomserver.example",
    "turn:turn.randomserver.example:5677?transport=udp",
    "turn:turn.randomserver.example:5677?transport=tcp"
]

guard let server = QBRTCICEServer.init(urls: urls, username: username, password: password) else {
    return
}
QBRTCConfig.setICEServers([server])
