Renderizar um cartão – iOS

Veja a seguir como renderizar um cartão usando o SDK do iOS.

Criar um cartão com base em uma cadeia de caracteres JSON

Um AdaptiveCard é gerado com base em uma cadeia de caracteres 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 um cartão

O renderador assume a configuração de host e cartão adaptável. HostConfig pode ser nulo e, se nulo, o valor padrão será usado. A UIView retornada usa um AutoLayout. A largura ficará restrita ao valor definido por widthConstraint. Se o valor 0 for usado, ele não será associado. A altura não é associada e, quando retornada, ela terá a altura das somas de todo o conteúdo renderizado. Para associar a dimensão da exibição, use NSLayoutConstraint. A dimensão exata estará acessível no contexto de viewDidLayoutSubview do ViewController de sua superexibição ou seu método com o mesmo nome se ACRViewController for usado.

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