Existe-t-il un moyen d'utiliser Touch ID (scanner d'empreintes digitales) d'Apple sur iOS Simulator?

Je travaille sur une application qui nécessiterait une authentification Touch ID, est-il donc possible d'utiliser Touch ID (scanner d'empreintes digitales) dans le simulateur?

Veuillez également partager une sorte d'exemple de code pour l'utilisation du framework LocalAuthentication.

Depuis Xcode 7, le simulateur prend en charge "touchID". La réponse ci-dessous contient de plus amples informations.

Depuis la dernière version bêta (6), il n'y a aucun moyen de simuler un balayage d'empreintes digitales sur le simulateur. Pour être honnête, je doute que cela soit inclus même dans les versions ultérieures.

Vous devrez tester sur l'appareil.

Pour utiliser le cadre d'authentification en ce moment, vous avez besoin de: * XCode 6 * iPhone 5s avec iOS 8

Les étapes que vous devez effectuer sont les suivantes:

Vérifiez si l'appareil prend en charge la validation des empreintes digitales et si une empreinte digitale est enregistrée: 

@import LocalAuthentication;

// Get the local authentication context:
LAContext *context = [[LAContext alloc] init];

// Test if fingerprint authentication is available on the device and a fingerprint has been enrolled.
if ([context canEvaluatePolicy: LAPolicyDeviceOwnerAuthenticationWithBiometrics error:nil])
{
    NSLog(@"Fingerprint authentication available.");
}

Validez une empreinte digitale uniquement: 

[context evaluatePolicy:LAPolicyDeviceOwnerAuthenticationWithBiometrics localizedReason:@"Authenticate for server login" reply:^(BOOL success, NSError *authenticationError){
    if (success) {
        NSLog(@"Fingerprint validated.");
    }
    else {
        NSLog(@"Fingerprint validation failed: %@.", authenticationError.localizedDescription);
    }
}];

Validez une empreinte digitale ou le code d'accès de l'appareil en fonction du choix de l'utilisateur: Cela dépasse un peu la portée d'une question ici, veuillez trouver plus d'informations sur: https://www.secsign.com/fingerprint-validation-as-an-alternative-to-passcodes/

XCODE 7 beta prend en charge le test de l'authentification Touch ID dans iPhone Simulator.Vous pouvez essayer ceci pour vos tests.
