Code pour partager le path d'access / le file entre une extension de partage et une application iOS

J'ai ajouté une extension de partage pour mon application dire SAMPLE (existe déjà sur l'App Store), appelé laisse dire SAMPLESHARE. Chaque fois qu'un user, par exemple, prend une photo et essaie de la partager, je veux qu'il passe par un controller de vue d'une fonctionnalité Open In, et qu'il n'obtienne pas le dialog Post d'Apple, en le contournant fondamentalement. J'essaie donc de partager l'image entre l'extension de partage et mon application, en créant un groupe d'applications partagé entre l'application et le plugin, puis en transmettant les paths d'access au file openURL du délégué d'application de mon application.

Donc, dans mon principal requestur d'application, j'ai

- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSSsortingng *)sourceApplication annotation:(id)annotation { return [[SAMPLEExternalFileHandler shared] handleExternalFileURL:url]; }

ce que j'utilise fondamentalement pour vérifier chaque fois si j'ai un path de file d'URL qui doit ouvrir un stream différent.

Dans mon PARTAGE, j'ai

J'ai fondamentalement utilisé un certain code de licence de commons d'Internet (site réputé), qui prétend avoir passé le process d'examen de magasin d'application.

Il y a deux solutions de contournement dans le code, l'une est d'appeler OpenURL depuis l'extension de partage (ce qui semble impossible n'est pas encore possible normalement sans solutions de contournement sur iOS 8.3 et supérieur) et la seconde est de masquer le dialog post et le keyboard cette pomme fournit par défaut quand quelqu'un clique sur partager. Cela marche.

J'ai deux questions

 1.) Will this be accepted on the app store? -- basically how are apps like facebook/whatsapp doing it and they are being accepted? 2.) Whenever I run this, it says `NSExtensionActivationRule` if set to `TRUEPREDICATE` will be rejected in review, what should the value be?

METTRE À JOUR:

Donc, parcourant la documentation, j'ai trouvé un correctif pour la question 2, et j'ai changé cela. Maintenant tout fonctionne, et il n'y a pas de TRUEPREDICATE , cela sera-t-il accepté dans le magasin ou existe-t-il un autre moyen de le faire?

MISE À JOUR 2:

J'ai maintenant utilisé NSUserDefaults pour passer datatables de l'extension à l'application, devinez que c'est aussi une condition pour le partage de données.

METTRE À JOUR

L'application a été acceptée dans la révision en utilisant NSUSERDEFAULTS comme mécanisme de transmission de message. Voici les étapes.

Votre question est un peu foirée, mais s'il s'agit de transmettre des données d'une application à une autre application, vous avez une excellente solution pour ce qui est de UIPasteboard

Si vous ne rencontrez aucun problème pour passer d'une application à l'autre à l'aide de gestionnaires d'URL personnalisés, il vous rest deux étapes supplémentaires.

Étape 1
Dans votre première application qui est responsable du transfert des données, implémentez ces methods, puis appelez l'URL personnalisée.

 UIPasteboard *pasteboard = [UIPasteboard generalPasteboard]; [[UIPasteboard generalPasteboard] setImage:passImage];

Étape 2
Dans votre controller de vue cible, appelez de nouveau UIPasteboard et récupérez datatables.

 UIPasteboard *pasteboard = [UIPasteboard generalPasteboard]; UIImage *getImage = pasteboard.image;

S'il vous plaît noter que vous passez un UIImage et vous l'obtenez dans le même type

Si vous ne voulez pas afficher la boîte de dialog par défaut d'Apple. Doit être hérité de UIViewController pas @interface ShareViewController: SLComposeServiceViewController
Dans le document de développeur Apple, n'autorisez pas l'application Extensions à ouvrir directement l'application contenant l'application Today.
