Protocolo NowChatThemeable - iOS

O protocolo NowWebThemeable fornece propriedades que permitem substituir as cores usadas em páginas da Web hospedadas em sua instância ServiceNow em uma exibição da Web nativa.

Este protocolo contém um objeto de cor NowWebColoring que estende ColorAdaptable. O ColorAdaptable é usado para determinar automaticamente se as cores claras ou escuras devem ser exibidas com base na configuração de exibição do dispositivo.

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

O protocolo NowChatColoring contém NowUIColoring. Esta propriedade é usada para fazer referência a variáveis de cor padrão que o NowWebThemeable pode usar.

Para obter informações adicionais sobre como tematizar a IU, consulte Use NowUIColoring para o tema NowWebTheme e NowChatTheme no Guia do desenvolvedor do Mobile SDK - iOS.

Definir ChatColors usando cores padrão

/// Sample structure for using default colors that comes with Mobile SDK.
struct ChatColors: NowUIColoring {
}

Definir ChatColors usando cores personalizadas

/// Use Custom Colors with light and dark theme

    private var defaultTheme: NowChatDefaultTheme {
        NowChatDefaultTheme(nowUITheme: NowUIDefaultTheme())

Definir a estrutura do ChatTheme com o protocolo NowChatThemeable

struct CarrascoChatTheme: NowChatThemeable {
    var color: NowChatColoring
    
    struct Color: NowChatColoring {
        var nowUIColor: NowUIColoring
    
        var backgroundPrimary: UIColor
        var backgroundSecondary: UIColor
        var backgroundPrimaryActionable: UIColor
        var backgroundSecondaryActionable: UIColor

        var separatorTertiary: UIColor
        var borderTertiary: UIColor
        var shadow: UIColor
        var linkSecondary: UIColor

        init(inputs: ChatColors) {
            nowUIColor = ThemeColor(inputs)

Instanciar o objeto ChatTheme passando ChatColor como entrada

let chatTheme = CarrascoChatTheme(chatColors: ChatColors())

Passar o objeto ChatTheme para NowChatService.makeChatUI ()

func makeChatScreen() -> UIViewController? {
  guard let chatService = chatService else { return nil }
  let result = chatService.makeChatUI(theme: CarrascoChatTheme(chatColors: ChatColors()))
        
  switch result {
  case .success(let chatViewController):
    return chatViewController
  case .failure(let error):
    debugPrint("Chat screen creation failed with error: \(error)")
    return nil
  }
}
