Merender kartu - iOS

Berikut cara merender kartu menggunakan iOS SDK.

Membuat kartu dari string JSON

AdaptiveCard dihasilkan dari string 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;

Merender Kartu

Perender mengambil kartu adaptif dan konfigurasi host. HostConfig dapat nihil, dan jika nihil, nilai default akan digunakan. UIView yang dikembalikan menggunakan autolayout. Lebar akan menjadi batasan nilai yang ditetapkan oleh widthConstraint. Jika nilai 0 digunakan, nilai tersebut tidak akan terikat. Tinggi tidak terikat, dan ketika dikembalikan akan memiliki tinggi dari jumlah semua konten yang dirender. Untuk mengikat dimensi tampilan, gunakan NSLayoutConstraint. Dimensi yang tepat dapat diakses dari konteks viewDidLayoutSubview viewcontroller superview atau metodenya dengan nama yang sama jika ACRViewController digunakan.

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