Erreur de compilation SCNetworkReachability

Question

J'ai essayé de compiler l'exemple de code d'Ercia Sadun ici , mais cette erreur s'est produite:

 warning: in /Users/interdev/iphone source code/Web Browser/Classes/SystemConfiguration.framework/SystemConfiguration, missing required architecture i386 in file

... Même après avoir ajouté systemConfiguration.framework, il a signalé la même erreur. Pourquoi a-t-il fait cela et comment puis-je le faire fonctionner?

Answer 1

Quel SystemConfiguration.framework avez-vous ajouté? La première ligne clairement énoncée

avertissement: dans /Users/interdev/iphone source code/Web Browser/Classes/SystemConfiguration.framework/SystemConfiguration , il manque l'architecture requise i386 dans le fichier

Mais vous devez ajouter celui du SDK, en /Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator4.3.sdk/System/Library/Frameworks .

Le cadre doit être ajouté par "Ajouter un cadre existant ..." dans le menu contextuel du projet.
