Representación de una tarjeta: iOS

Aquí se muestra cómo representar una tarjeta mediante el SDK de iOS.

Creación de una tarjeta a partir de una cadena JSON

AdaptiveCard se genera a partir de la cadena JSON

NSString *jsonStr = @"{ \"type\": \"AdaptiveCard\", \"version\": \"1.0\", \"body\": [ { \"type\": \"Image\", \"url\": \"http://adaptivecards.io/content/adaptive-card-50.png\", \"horizontalAlignment\":\"center\" }, { \"type\": \"TextBlock\", \"horizontalAlignment\":\"center\", \"text\": \"Hello **Adaptive Cards!**\" } ], \"actions\": [ { \"type\": \"Action.OpenUrl\", \"title\": \"Learn more\", \"url\": \"http://adaptivecards.io\" }, { \"type\": \"Action.OpenUrl\", \"title\": \"GitHub\", \"url\": \"http://github.com/Microsoft/AdaptiveCards\" } ] }";
ACOAdaptiveCardParseResult *cardParseResult = [ACOAdaptiveCard fromJson:jsonStr];

/// access for parse warnings and errors
NSArray<NSError *> *errors = cardParseResult.parseErrors;
NSArray<ACRParseWarning *> *warnings = cardParseResult.parseWarnings;

Renderizar una tarjeta

El representador toma la tarjeta adaptable y la configuración del host. HostConfig puede ser nulo y, si es nulo, se usará el valor predeterminado. UiView devuelto usa la función autolayout. El ancho será una restricción para el valor establecido por widthConstraint. Si se usa el valor 0, no se enlazará. La altura no está restringida y, al devolverse, tendrá la altura de la suma de todos los contenidos representados. Para restringir la dimensión de la vista, use NSLayoutConstraint. La dimensión exacta se puede obtener desde el contexto de viewDidLayoutSubview del controlador de vista de su supervista, o su método con el mismo nombre si se utiliza ACRViewController.

ACRRenderResult *renderResult = nil;
if(cardParseResult.isValid){
    renderResult = [ACRRenderer render:cardParseResult.card config:nil widthConstraint:335];
}
