Basic Video Chat Sample App
===============================
The Basic-Video-Chat app is a very simple application meant to get a new developer
started using the OpenTok iOS SDK.
Quick Start
-----------
To use this application:
1. Follow the instructions in the [Quick Start](../README.md#quick-start)
section of the main README file for this repository.
Among other things, you need to set values for the `kApiKey`, `kSessionId`,
and `kToken` constants. See [Obtaining OpenTok
Credentials](../README.md#obtaining-opentok-credentials)
in the main README file for the repository.
2. When you run the application, it connects to an OpenTok session and
publishes an audio-video stream from your device to the session.
3. Run the app on a second client. You can do this by deploying the app to an
iOS device and testing it in the simulator at the same time. Or you can use
the browser_demo.html file to connect in a browser (see the following
section).
When the second client connects, it also publishes a stream to the session,
and both clients subscribe to (view) each other’s stream.
Application Notes
-----------------
* Follow the code from the `ViewController.viewDidLoad(_:)` method through
to the OpenTok callbacks to see how streams are created and handled in
the OpenTok iOS SDK.
* By default, all delegate methods from classes in the OpenTok iOS SDK are
invoked on the main queue. This means that you can directly modify the view
hierarchy from inside the callback, without any asynchronous callouts.
* When the main view loads, the ViewController calls the
`OTSession.initWithApiKey(_:, sessionId:,delegate:)` method to initialize
a Session object. The app then calls the
`OTSession.connectWithToken(_:, error:)` to connect to the session. The
`OTSessionDelegate.sessionDidConnect(_:)` message is sent when the app
connects to the OpenTok session.
* The `doPublish()` method of the app initializes a publisher and passes it
into the `OTSession.publish(_:,error:)` method. This publishes an
audio-video stream to the session.
* The `OTSessionDelegate.session(_:,streamCreated:)` message is sent when
a new stream is created in the session. In response, the
method calls `OTSubscriber(stream:,delegate:)`,
passing in the OTStream object. This causes the app to subscribe to the
stream.
To add a second publisher (which will display as a subscriber in your emulator), either run the app a second time in an iOS device or use the OpenTok Playground to connect to the session in a supported web browser (Chrome, Firefox, or Internet Explorer 10-11) by following the steps below:
1. Go to [OpenTok Playground](https://tokbox.com/developer/tools/playground) (must be logged into your [Account](https://tokbox.com/account))
2. Select the **Join existing session** tab
3. Copy the session ID you used in your project file and paste it in the **Session ID** input field
4. Click **Join Session**
5. On the next screen, click **Connect**, then click **Publish Stream**
6. You can adjust the Publisher options (not required), then click **Continue** to connect and begin publishing and subscribing
Configuration Notes
-------------------
* You can test in the iOS Simulator or on a supported iOS device. However, the
XCode iOS Simulator does not provide access to the camera. When running in
the iOS Simulator, an OTPublisher object uses a demo video instead of the
camera.

================================================
# Contributor Covenant Code of Conduct
## Our Pledge
We as members, contributors, and leaders pledge to make participation in our
community a harassment-free experience for everyone, regardless of age, body
size, visible or invisible disability, ethnicity, sex characteristics, gender
identity and expression, level of experience, education, socio-economic status,
nationality, personal appearance, race, religion, or sexual identity
and orientation.
We pledge to act and interact in ways that contribute to an open, welcoming,
diverse, inclusive, and healthy community.
## Our Standards
Examples of behavior that contributes to a positive environment for our
community include:
- Demonstrating empathy and kindness toward other people
- Being respectful of differing opinions, viewpoints, and experiences
- Giving and gracefully accepting constructive feedback
- Accepting responsibility and apologizing to those affected by our mistakes,
and learning from the experience
- Focusing on what is best not just for us as individuals, but for the
overall community
Examples of unacceptable behavior include:
- The use of sexualized language or imagery, and sexual attention or
advances of any kind
- Trolling, insulting or derogatory comments, and personal or political attacks
- Public or private harassment
- Publishing others' private information, such as a physical or email
address, without their explicit permission
- Other conduct which could reasonably be considered inappropriate in a
professional setting
## Enforcement Responsibilities
Community leaders are responsible for clarifying and enforcing our standards of
acceptable behavior and will take appropriate and fair corrective action in
response to any behavior that they deem inappropriate, threatening, offensive,
or harmful.
Community leaders have the right and responsibility to remove, edit, or reject
comments, commits, code, wiki edits, issues, and other contributions that are
not aligned to this Code of Conduct, and will communicate reasons for moderation
decisions when appropriate.
## Scope
This Code of Conduct applies within all community spaces, and also applies when
an individual is officially representing the community in public spaces.
Examples of representing our community include using an official e-mail address,
posting via an official social media account, or acting as an appointed
representative at an online or offline event.
## Enforcement
Instances of abusive, harassing, or otherwise unacceptable behavior may be
reported to the community leaders responsible for enforcement at
devrel@vonage.com.
All complaints will be reviewed and investigated promptly and fairly.
All community leaders are obligated to respect the privacy and security of the
reporter of any incident.
## Enforcement Guidelines
Community leaders will follow these Community Impact Guidelines in determining
the consequences for any action they deem in violation of this Code of Conduct:
### 1. Correction
**Community Impact**: Use of inappropriate language or other behavior deemed
unprofessional or unwelcome in the community.
**Consequence**: A private, written warning from community leaders, providing
clarity around the nature of the violation and an explanation of why the
behavior was inappropriate. A public apology may be requested.
### 2. Warning
**Community Impact**: A violation through a single incident or series
of actions.
**Consequence**: A warning with consequences for continued behavior. No
interaction with the people involved, including unsolicited interaction with
those enforcing the Code of Conduct, for a specified period of time. This
includes avoiding interactions in community spaces as well as external channels
like social media. Violating these terms may lead to a temporary or
permanent ban.
### 3. Temporary Ban
**Community Impact**: A serious violation of community standards, including
sustained inappropriate behavior.
**Consequence**: A temporary ban from any sort of interaction or public
communication with the community for a specified period of time. No public or
private interaction with the people involved, including unsolicited interaction
with those enforcing the Code of Conduct, is allowed during this period.
Violating these terms may lead to a permanent ban.
### 4. Permanent Ban
**Community Impact**: Demonstrating a pattern of violation of community
standards, including sustained inappropriate behavior, harassment of an
individual, or aggression toward or disparagement of classes of individuals.
**Consequence**: A permanent ban from any sort of public interaction within
the community.

## CallKit Integration with OpenTok
A sample app to demonstrate how to integrate the [CallKit](https://developer.apple.com/documentation/callkit) into OpenTok iOS SDK. This sample app is built based on the [SpeakerBox](https://developer.apple.com/library/content/samplecode/Speakerbox/Introduction/Intro.html) app from [WWDC 2016 CallKit Session](https://developer.apple.com/videos/play/wwdc2016/230/)
### Install the project files
Use CocoaPods to install the project files and dependencies.
1. Install CocoaPods as described in [CocoaPods Getting Started](https://guides.cocoapods.org/using/getting-started.html#getting-started).
1. In Terminal, `cd` to your project directory and type `pod install`. (Sometimes, `pod update` is magical)
1. Reopen your project in Xcode using the new `*.xcworkspace` file.
### Configure and build the app
Configure the sample app code. Then, build and run the app.
1. The application **requires** values for **API Key**, **Session ID**, and **Token**. In the sample, you can get these values at the [OpenTok Developer Dashboard](https://dashboard.tokbox.com/). For production deployment, you must generate the **Session ID** and **Token** values using one of the [OpenTok Server SDKs](https://tokbox.com/developer/sdks/server/).
1. Replace the following empty strings with the corresponding **API Key**, **Session ID**, and **Token** values in `AppDelegate.swift`:
```swift
let apiKey = ""
let sessionId = ""
let token = ""
```
1. Use Xcode to build and run the app on an iOS simulator or device.
### Exploring the sample app
1. **Make a call**:
The iOS system boosts the call priority of the app. Then, the app starts publishing to OpenTok platform. You won't notice any differences until you go to the home screen. Two ways to verify:
- A badge in home screen indicating an ongoing VoIP call.
- An incoming native phone call will not interrupt the current VoIP call, instead it shows the option menu.
***You will need a device to test the followings***
2. **Simulate an incoming call**
The native incoming call screen appears. Upon acceptance, the iOS system opens the app and boosts the call priority. Then, the app starts publishing to OpenTok platform.
 ---> 
3. **Simulate an incoming call after 3s(Background)** (After clicking the button, please lock your cell phone to test this scenario.)
The system wakes up your cell phone by making a native calling screen appear. Upon acceptance (a slider is shown instead of two buttons for the locked screen), the phone stays locked and boosts the call priority. Then, the app (which runs in the background during that time) starts publishing to OpenTok platform.
 ---> 
4. **Without simulation, use a push server or [NWPusher](https://github.com/noodlewerk/NWPusher) to call**
This requires a few more steps to test:
- create your certificate
- configure your push notification backend or NWPusher
- locate your device token for testing (launch the app and get it from the console)
- send a remote notification from your backend or NWPusher
**Notice**: You might want to use [OpenTok.js Sample App](https://github.com/opentok/opentok-web-samples/tree/master/Basic%20Video%20Chat) to test the sample app together.
### Exploring the codes
A `CXProvider` object is responsible for reporting out-of-band notifications that occur to the system. To create one, you first need to initialize a `CXProviderConfiguration` object, which encapsulates the behaviors and capabilities of calls, to pass on to the `CXProvider` initializer. In order to receive telephony events of the provider, the provider needs to specify an object conforming to the `CXProviderDelegate` protocol.
```swift
// create a provider configuration
let localizedName = NSLocalizedString("CallKitDemo", comment: "Name of application")
let providerConfiguration = CXProviderConfiguration(localizedName: localizedName)
providerConfiguration.supportsVideo = false
providerConfiguration.maximumCallsPerCallGroup = 1
providerConfiguration.supportedHandleTypes = [.phoneNumber]
providerConfiguration.iconTemplateImageData = UIImagePNGRepresentation(#imageLiteral(resourceName: "IconMask"))
providerConfiguration.ringtoneSound = "Ringtone.caf"
// set up a provider
provider = CXProvider(configuration: providerConfiguration)
provider.setDelegate(self, queue: nil)
```
The `CXProviderDelegate` protocol defines events of the telephony provider (`CXProvider`) such as the call starting, the call being put on hold, or the provider’s audio session is activated.
```swift
// MARK: CXProviderDelegate
func providerDidReset(_ provider: CXProvider) {
print("Provider did reset")
}
func provider(_ provider: CXProvider, perform action: CXStartCallAction) {
print("Provider performs the start call action")
/*
Configure the audio session, but do not start call audio here, since it must be done once
the audio session has been activated by the system after having its priority elevated.
*/
}
func provider(_ provider: CXProvider, perform action: CXAnswerCallAction) {
print("Provider performs the answer call action")
/*
Configure the audio session, but do not start call audio here, since it must be done once
the audio session has been activated by the system after having its priority elevated.
*/
}
func provider(_ provider: CXProvider, perform action: CXEndCallAction) {
print("Provider performs the end call action")
// Trigger the call to be ended via the underlying network service.
}
func provider(_ provider: CXProvider, perform action: CXSetHeldCallAction) {
print("Provider performs the hold call action")
}
func provider(_ provider: CXProvider, perform action: CXSetMutedCallAction) {
print("Provider performs the mute call action")
}
```
The following methods indicate whether your VoIP call has been successfully priority boosted or recovered.
```swift
func provider(_ provider: CXProvider, timedOutPerforming action: CXAction) {
print("Timed out \(#function)")
// React to the action timeout if necessary, such as showing an error UI.
}
func provider(_ provider: CXProvider, didActivate audioSession: AVAudioSession) {
// Start call audio media, now that the audio session has been activated after having its priority boosted.
}
func provider(_ provider: CXProvider, didDeactivate audioSession: AVAudioSession) {
/*
Restart any non-call related audio now that the app's audio session has been
de-activated after having its priority restored to normal.
*/
}
```
Let's explore how to make a call and answer a call on behalf of a user. To do that, we need a `CXCallController` object to interact with the system.
The `CXCallController` object takes a `CXTransaction` object to request a telephony action (which will later trigger delegate methods above if succeed). To specify a telephony action in a transaction, you need to create your desired action object and associate them with the transaction. Each telephony action has a corresponding `CXAction` class such as `CXEndCallAction` for ending a call, `CXSetHeldCallAction` for setting a call on hold.
Once you have it all ready, invoke the `request(_:completion:)` by passing a ready transaction object. Here's how you start a call:
```swift
// create a CXAction
let startCallAction = CXStartCallAction(call: UUID(), handle: CXHandle(type: .phoneNumber, value: handle))
// create a transaction
let transaction = CXTransaction()
transaction.addAction(startCallAction)
// create a label
let action = "startCall"
callController.request(transaction) { error in
if let error = error {
print("Error requesting transaction: \(error)")
} else {
print("Requested transaction \(action) successfully")
}
}
```
As for answering a call, the `CallKit` framework provides a convenient API to present a native calling UI like the screen-shot below. By invoking `reportNewIncomingCall(with:update:completion:)` on the provider, you will have the same experience as receiving a native phone call. Often, this piece of code works with VoIP remote notification to make calls to a device/person like WhatsApp, WeChat, and Messenger etc.
```swift
// Construct a CXCallUpdate describing the incoming call, including the caller.
let update = CXCallUpdate()
update.remoteHandle = CXHandle(type: .phoneNumber, value: handle)
// Report the incoming call to the system
provider.reportNewIncomingCall(with: uuid, update: update) { error in
/*
Only add incoming call to the app's list of calls if the call was allowed (i.e. there was no error)
since calls may be "denied" for various legitimate reasons. See CXErrorCodeIncomingCallError.
*/
}
```
### A glitch
There is a small [issue](https://forums.developer.apple.com/thread/64544) when accepting a call from a locked screen. The underlying audio session does not get activated propertly inside the CallKit framework. Apple's engineers propose a workaround by setting up the audio session as early as possible to make the case work out temporarily:
```
then a workaround would be to configure your app's audio session (call `configureAudioSession()`) earlier in your app's lifecycle, before the `-provider:performAnswerCallAction:` method is invoked.
```
