Swift

Création de l'interface de connexion

Pour pouvoir vous connecter, vous devez ajouter trois éléments à l'écran :

A UIButton pour se connecter à Alice
A UIButton pour se connecter à Bob
A UILabel pour afficher l'état de la connexion.

Ouvrir ViewController.swift et l'ajouter par programme en remplaçant tout le contenu du fichier par ce qui suit :

import UIKit
import VonageClientSDKVoice

class ViewController: UIViewController {

    let loginAliceButton = UIButton(type: .system)
    let loginBobButton = UIButton(type: .system)
    let connectionStatusLabel = UILabel()
    
    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view.
        
        loginAliceButton.setTitle("Log in as Alice", for: .normal)
        loginAliceButton.translatesAutoresizingMaskIntoConstraints = false
        view.addSubview(loginAliceButton)
        
        loginBobButton.setTitle("Log in as Bob", for: .normal)
        loginBobButton.translatesAutoresizingMaskIntoConstraints = false
        view.addSubview(loginBobButton)
        
        connectionStatusLabel.text = ""
        connectionStatusLabel.textAlignment = .center
        connectionStatusLabel.translatesAutoresizingMaskIntoConstraints = false
        view.addSubview(connectionStatusLabel)
        
        NSLayoutConstraint.activate([
            loginAliceButton.centerYAnchor.constraint(equalTo: view.centerYAnchor),
            loginAliceButton.centerXAnchor.constraint(equalTo: view.centerXAnchor),
            loginAliceButton.leadingAnchor.constraint(equalTo: view.leadingAnchor, constant: 20),
            loginAliceButton.trailingAnchor.constraint(equalTo: view.trailingAnchor, constant: -20),
            
            loginBobButton.centerXAnchor.constraint(equalTo: view.centerXAnchor),
            loginBobButton.leadingAnchor.constraint(equalTo: view.leadingAnchor, constant: 20),
            loginBobButton.trailingAnchor.constraint(equalTo: view.trailingAnchor, constant: -20),
            loginBobButton.topAnchor.constraint(equalTo: loginAliceButton.bottomAnchor, constant: 20),
            
            connectionStatusLabel.centerXAnchor.constraint(equalTo: view.centerXAnchor),
            connectionStatusLabel.leadingAnchor.constraint(equalTo: view.leadingAnchor, constant: 20),
            connectionStatusLabel.trailingAnchor.constraint(equalTo: view.trailingAnchor, constant: -20),
            connectionStatusLabel.topAnchor.constraint(equalTo: loginBobButton.bottomAnchor, constant: 20)
        ])
    }
}
