Add custom components to the call

Customize the foreground view

If you want to add some custom components at the top level of the view, such as you want to display the user avatars when the video view is displayed, add user-level icons, etc., then you can use ZegoUIKitPrebuiltCallVCDelegate.getForegroundView protocol. The getForegroundView requires you (the developer) to return a custom view that will be placed at the top of the view.

Here is the reference code:

Basic call

With call invitation

class ViewController: UIViewController {
    
    let selfUserID: String = "userID"
    let selfUserName: String = "userName"
    let yourAppID: UInt32 = YourAppID 
    let yourAppSign: String = YourAppSign
    let callID: String = "testCallID"
    
    override func viewDidLoad() {
        super.viewDidLoad()
    }
    @IBAction func makeNewCall(_ sender: Any) {
        
        // Modify your custom configurations here.
        let config: ZegoUIKitPrebuiltCallConfig = ZegoUIKitPrebuiltCallConfig.oneOnOneVideoCall()

        config.turnOnCameraWhenjoining = false;
        config.audioVideoViewConfig.showCameraStateOnView = false;
        config.bottomMenuBarConfig.buttons = [.toggleMicrophoneButton,.hangUpButton,.swtichAudioOutputButton]

        let callVC = ZegoUIKitPrebuiltCallVC.init(yourAppID, appSign: yourAppSign, userID: selfUserID, userName: selfUserName ?? "", callID: callID, config: config)
        
        callVC.delegate = self

        callVC.modalPresentationStyle = .fullScreen
        self.present(callVC, animated: true, completion: nil)
    }
    
    func getForegroundView(_ userInfo: ZegoUIKitUser?) -> UIView? {
        return YourCustomView()
    }

Customize the audio view

If you need to customize the user's view in audio mode, for example, setting the background image, you can use largeViewBackgroundImage, smallViewBackgroundImage, largeViewBackgroundColor, smallViewBackgroundColor in ZegoLayoutPictureInPictureConfig.

These configurations are only valid when the user turns off the camera (because the video view will be displayed automatically when the camera is on).

Here is the reference code:

Basic call

With call invitation

class ViewController: UIViewController {
    
    let selfUserID: String = "userID"
    let selfUserName: String = "userName"
    let yourAppID: UInt32 = YourAppID 
    let yourAppSign: String = YourAppSign
    let callID: String = "testCallID"
    
    override func viewDidLoad() {
        super.viewDidLoad()
    }
    @IBAction func makeNewCall(_ sender: Any) {
        
        // Modify your custom configurations here.
        let config: ZegoUIKitPrebuiltCallConfig = ZegoUIKitPrebuiltCallConfig.oneOnOneVideoCall()

        let layout: ZegoLayout = ZegoLayout()
        layout.mode = .pictureInPicture
        let pipConfig: ZegoLayoutPictureInPictureConfig = ZegoLayoutPictureInPictureConfig()
        pipConfig.largeViewBackgroundColor = UIColor.darkGray
        pipConfig.smallViewBackgroundColor = UIColor.lightGray
        layout.config = pipConfig
        config.layout = layout

        let callVC = ZegoUIKitPrebuiltCallVC.init(yourAppID, appSign: yourAppSign, userID: selfUserID, userName: selfUserName ?? "", callID: callID, config: config)
        callVC.modalPresentationStyle = .fullScreen
        self.present(callVC, animated: true, completion: nil)
    }
