Crash d'application aléatoire sur certains appareils iOS9 après la fermeture du contrôleur de la caméra

Question

J'ai reçu le rapport de panne suivant, envoyé par un utilisateur, mais je ne connais pas la raison possible. Le crash de l'application au hasard lorsque vous appelez

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info 

délégué, après la prise de l'utilisateur « photo utilisation » sur le contrôleur de la caméra. Dans ce délégué, je fais un peu de traitement d'image (compression et redimensionnement) et je télécharge l'image résultante à un serveur Web:

Modifier: l'accident se produit au hasard après avoir appelé:

NSURLConnection sendAsynchronousRequest 

uniquement sur les périphériques iPhone6 ​​

Voici le rapport de l'accident:

Answer 2

Je recevais une erreur similaire dans une application iPad. Donc, assurez-vous que mon appareil photo était en cours d'exécution sur mainThread résolu mon problème:

[[NSOperationQueue mainQueue] addOperationWithBlock:^{ 
    [self openCamera]; // Call your camera method here 
}]; 

J'espère que cela peut vous aider.
