App crash iPhone 5s ios 7.1.1

Question

Je soumets mon application à l'App Store et après 5 jours, ils le rejettent. Ils me disent que l'application s'est écrasée sur 7.1.1 iPhone 5s sous iOS 7.1.1.

Est-ce un problème sur la bibliothèque AFNetworking?

Nous vous remercions de votre aide.

Voici le rapport de l'accident:

Class captureDeviceClass = NSClassFromString(@"AVCaptureDevice"); 
if (captureDeviceClass != nil) { 
    AVCaptureDevice *device = [AVCaptureDevice defaultDeviceWithMediaType:AVMediaTypeVideo]; 
    [device lockForConfiguration:nil]; 
    [device setFlashMode:AVCaptureFlashModeOff]; 
    [device unlockForConfiguration]; 
} //It crash in this line [device setFlashMode:AVCaptureFlashModeOff]; 

Answer 1

A partir de documents d'Apple:

@property(nonatomic) AVCaptureFlashMode flashMode 

Discussion 
Before changing the value of this property, 
you must call lockForConfiguration: 
to acquire exclusive access to the device’s configuration properties. 
Otherwise, setting the value of this property raises an exception. 
When you are done configuring the device, call unlockForConfiguration 
to release the lock and allow other devices to configure the settings. 

Voilà pourquoi il est écraser, vous avez besoin d'acquérir un accès exclusif.

se contente d'ajouter:

if ([device isFlashModeSupported:AVCaptureFlashModeOff) { 
    NSError *error; 
    if ([device lockForConfiguration:&error) { 
     //It's now safe to add your original code here.... 
     [device setFlashMode:AVCaptureFlashModeOff]; 
    } 

    else 
     NSLog(@"ERROR: %@", [error localizedDescription]); 
} 

De cette façon, s'il y a une raison pour laquelle l'application ne peut pas verrouiller le mode flash que vous voulez, vous obtiendrez une erreur. Il passera également au-dessus de sorte qu'il ne déclenchera pas et l'exception & crash.
