Protocole NowChatThemeable - iOS

Le protocole NowWebThemeable fournit des propriétés qui vous permettent de remplacer les couleurs utilisées dans les pages Web hébergées sur votre ServiceNow instance dans une vue Web native.

Ce protocole contient un objet de couleur NowWebColoring qui étend ColorAdaptable. ColorAdaptable est utilisé pour déterminer automatiquement s’il faut afficher des couleurs claires ou foncées en fonction des paramètres d’affichage de l’appareil.

public protocol NowChatThemeable {
    var color: NowChatColoring { get }
}

Le protocole NowChatColoring contient NowUIColoring. Cette propriété est utilisée pour référencer les variables de couleur par défaut que NowWebThemeable peut utiliser.

Pour plus d’informations sur la façon de définir le thème de l’interface utilisateur, consultez Utiliser NowUIColoring pour le thème NowWebTheme et NowChatTheme le Guide du développeur du SDK mobile - iOS.
