.set(onVoiceCallClick: { user, group in
//Perform Your Action
})
2. SetOnVideoCallClick
The setOnVideoCallClick action is typically triggered when a video call is initiated, executing default actions. However, with the provided code snippet, you have the flexibility to easily customize or override this default behavior according to your specific preferences or requirements. 
let cometChatCallButton = CometChatCallButtons(width: 24, height: 24)
.set(onVideoCallClick: { user, group in
//Perform Your Action
  
})
3. SetOnError
You can customize this behavior by using the provided code snippet to override the On Error and improve error handling. 
let cometChatCallButton = CometChatCallButtons(width: 24, height: 24)
    .set(onError: { error in

})

​
Filters

Filters allow you to customize the data displayed in a list within a Component. You can filter the list based on your specific criteria, allowing for a more customized. Filters can be applied using RequestBuilders of Chat SDK. The CallButton component does not have any exposed filters.

​
Events

Events are emitted by a Component. By using event you can extend existing functionality. Being global events, they can be applied in Multiple Locations and are capable of being Added or Removed. Events emitted by the Call buttons component is as follows.
EventDescription
onOutgoingCallAcceptedTriggers when the outgoing call is accepted.
onOutgoingCallRejectedTriggers when the outgoing call is rejected.
// View controller from your project where you want to listen events.
public class ViewController: UIViewController {

   public override func viewDidLoad() {
        super.viewDidLoad()

       // Subscribing for the listener to listen events from user module
        CometChatCallEvents.addListener("UNIQUE_ID", self as CometChatCallEventListener)
    }

}
 // Listener events from user module
extension  ViewController: CometChatCallEventListener {

    func onOutgoingCallAccepted(call: Call) {
        // Do Stuff
    }

    func onOutgoingCallRejected(call: Call){
        // Do Stuff
    }

    func onCallEnded(call: Call) {
        // Do Stuff
    }
}
Emitting Group Events
//emit this when the other user accepts the call
CometChatCallEvents.emitOnOutgoingCallAccepted(call: Call)

//emit this when the other user rejects a call
CometChatCallEvents.emitOnOutgoingCallRejected(call: Call)

//emit this when logged in user cancels a call
CometChatCallEvents.emitOnCallEnded(call: Call)
View Controller
public override func viewWillDisappear(_ animated: Bool) {
      // Uncubscribing for the listener to listen events from user module
      CometChatCallEvents.removeListener("LISTENER_ID_USED_FOR_ADDING_THIS_LISTENER")
}

​
Customization

To fit your app’s design requirements, you can customize the appearance of the conversation component. We provide exposed methods that allow you to modify the experience and behavior according to your specific needs.

​
Style

Using Style you can customize the look and feel of the component in your app, These parameters typically control elements such as the color, size, shape, and fonts used within the component.
1. CallButtons Style
You can customize the appearance of the CallButtons Component by applying the CallButtonStyle to it using the following code snippet. Global level styling 
CometChatCallButtons.style.audioCallButtonBackground = UIColor(hex: "#EDEAFA")
CometChatCallButtons.style.audioCallIconTint = UIColor(hex: "#6852D6")
CometChatCallButtons.style.videoCallButtonBackground = UIColor(hex: "#EDEAFA")
CometChatCallButtons.style.videoCallIconTint = UIColor(hex: "#6852D6")
Instance level styling 
let callButtonStyle = CallButtonStyle()
callButtonStyle.audioCallButtonBackground = UIColor(hex: "#EDEAFA")
callButtonStyle.audioCallIconTint = UIColor(hex: "#6852D6")
callButtonStyle.videoCallButtonBackground = UIColor(hex: "#EDEAFA")
callButtonStyle.videoCallIconTint = UIColor(hex: "#6852D6")
        
let callButton = CometChatCallButtons(width: 10, height: 10)
callButton.style = callButtonStyle

Functionality

These are a set of small functional customizations that allow you to fine-tune the overall experience of the component. With these, you can change text, set custom icons, and toggle the visibility of UI elements. Below is a list of customizations along with corresponding code snippets
PropertyDescriptionCode
hideVideoCallButtonHides the video call buttonhideVoiceCallButton = true
hideVoiceCallButtonHides the voice call buttonhideVoiceCallButton = true
set(user:User)Sets the User object for CometChatCallButtons..set(user:User)

set(customSoundForCalls:)Sets a custom sound for incoming and outgoing calls.set(customSoundForCalls: URL)
set(callSettingBuilder:)Function to build call settings based on call type and participants..set(callSettingBuilder { callType, participants in ... })

​
Advanced

For advanced-level customization, you can set custom views to the component. This lets you tailor each aspect of the component to fit your exact needs and application aesthetics. You can create and define your views, layouts, and UI elements and then incorporate those into the component. The Call Buttons component does not provide additional functionalities beyond this level of customization.

​
Configurations

Configurations offer the ability to customize the properties of each individual component within a Composite Component.
  • Configurations expose properties that are available in its individual components.

​
Outgoing Call

You can customize the properties of the Outgoing Call component by making use of the OutgoingCallConfiguration. You can accomplish this by employing the OutgoingCallConfiguration as demonstrated below: 
// Create an object of  OutgoingCallConfiguration
let outgoingCallConfiguration = OutgoingCallConfiguration()
All exposed properties of OutgoingCallConfiguration can be found under Outgoing Call. Properties marked with the 🛑 symbol are not accessible within the Configuration Object. Example Let’s say you want to change the style of the Outgoing Call subcomponent and, in addition, you only want to disable soundForCalls. You can modify the style using the OutgoingCallStyle property, disable sound for calls using .disable(soundForCalls: bool) property. 
let outgoingCallConfiguration = OutgoingCallConfiguration()
.disable(soundForCalls: true)

let cometChatCallButton = CometChatCallButtons(width: 24, height: 24)
cometChatCallButton.set(outgoingCallConfiguration: outgoingCallConfiguration)
cometChatCallButton.set(user: user)
To ensure that the CallButtons is properly configured, passing the controller is mandatory.
  • Swift
let callButtons = CometChatCallButtons(width: 24, height: 24)
callButtons.set(controller: UIViewController) // Passing the controller is required
