Exceptions and Errors on iOS

Cocoa, and by inheritance Cocoa Touch on iOS makes a clear distinction between what is an exception, and what is an error in your application. This should be obvious since NSException and NSError both inherit from the NSObject root class with no relations at all. Jayway Team Blog

“Auto-renewable Subscription” kündigen

Bieten Sie Ihre Kiosk-App in Apples Zeitungskiosk an, so haben Sie dafür ein Abonnement als In-App-Kauf angelegt. Wahrscheinlich haben Sie das Abo als “auto-renewable subscription” eingerichtet, so dass es sich für Ihre Leser automatisch verlängert, wenn sie es nicht 24-Stunden vor Ende der Abo-Periode kündigen. Viele iPad-Nutzer empfinden das als “Abo-Falle” oder Bevormundung. Noch schlimmer ist es, wenn die Nutzer nicht wissen, wie Sie die automatische Verlängerung verhindern können. Daher sollten Sie Ihre Kunden transparent informieren, wie sie das Abonnement kündigen können — und sich selbst mit dem Vorgang auseinander setzen, falls Ihre Abonnenten Sie danach fragen. tabletpublishing.mobi
