Je développe avec ObjectiveC une application SingleView pour iOS 11 avec un contrôleur de vue et une vue. Dans le storyboard Main.storyboard, par-dessus la vue, j'ai déposé une vue WebKit (WKWebView).
Je constate une panne à la fois dans le simulateur et sur un iPhone 6 fonctionnant sous iOS 11.0.1 :
Fermeture de l'application en raison d'une exception non attrapée 'NSInvalidUnarchiveOperationException', raison : 'Could not instantiate class named WKWebView'.
Ai-je besoin d'autre chose pour que cela fonctionne ? Il semble qu'il soit impossible d'instancier le WKWebView au réveil du storyboard.
Autres détails :
- Xcode version 9.0 9A235
- Lorsque je retire le WKWebView du Storyboard, le crash disparaît.
- App Base SDK - dernier iOS (iOS 11) ; cible de déploiement 11.0
- Utiliser le WebView(deprecated) -- UIWebView, ça marche
- Je n'ai pas essayé de l'instancier manuellement.
