Problèmes addInput AVCaptureSession avec ios8

J'ai une application avec AVCaptureSession qui fonctionne correctement avec les versions précédentes d'iOS, mais j'ai ensuite essayé de l'exécuter sur un appareil avec ios8, l'application s'est écrasée de façon sporadique. mais le problème n'a pas été résolu. Exception dans "[addInput session: input];" . S'il vous plaît aviser comment résoudre. Veuillez vérifier mon code ci-dessous et get une erreur dans [session addInput: input];

Impression de la description de l'erreur: Error Domain = AVFoundationErrorDomain Code = -11852 "Impossible d'utiliser la camera arrière" UserInfo = 0x17c076e0 {NSLocalizedDescription = Impossible d'utiliser la camera arrière, AVErrorDeviceKey =, NSLocalizedFailureReason = Cette application n'est pas autorisée à utiliser la camera arrière.}

Nous avons eu un problème avec cela aujourd'hui, essentiellement à partir d'iOS 8.0.2 et au-dessus l'access à la camera nécessite des parameters de confidentialité à la camera et non le roulement de la camera, une fois que cela a été activé le code a ensuite travaillé.

Vu la même erreur dans mon application aujourd'hui, je le gère avec une alerte qui contient un raccourci du button Paramètres pour les parameters de confidentialité de l'application.

 do { let captureInput:AVCaptureDeviceInput = try AVCaptureDeviceInput(device: self.device) ... } catch let error as NSError { let alert = UIAlertController(title:error.localizedDescription, message:error.localizedFailureReason, preferredStyle:.Alert) let settingsAction = UIAlertAction(title: "Settings", style: .Default) { (action) in UIApplication.sharedApplication().openURL(NSURL(ssortingng:UIApplicationOpenSettingsURLSsortingng)!) } alert.addAction(settingsAction) self.presentViewController(alert,animated:true,completion:nil) }
