Hello,
i'm trying to integrate Face Id on my IOS app , then to achieve that i used
the native interface using the LocalAuthentication framework, the problem
founded existe on the function that check the type of the biometry used
natively on the IOS device ''biometryType',
unfortunately, the xcode that you are using doesn't support the new
LocalAuthentication framework based on xcode 9.x .
that's my code :
LAContext *laContext = [[LAContext alloc] init];
NSError *error1 = nil;
NSString *stringToReturn = nil;
if (@available(iOS 8.0, *)) {
NSError *authError = nil;
BOOL isCanEvaluatePolicy = [laContext canEvaluatePolicy:
LAPolicyDeviceOwnerAuthenticationWithBiometrics error:&authError];
if (isCanEvaluatePolicy) {
if (@available(iOS 11.0, *)) {
switch (laContext.biometryType) {
case LABiometryTypeNone:
{
stringToReturn=@"NONE";
}
break;
case LABiometryTypeTouchID:
{
stringToReturn=@"TOUCHID";
}
break;
case LABiometryTypeFaceID:
{
stringToReturn=@"FACEID";
}
break;
default:
break;
}
} else {
stringToReturn=@"TOUCHID";
}
} else {
stringToReturn=@"NONE";
}
} else {
// Fallback on earlier versions
stringToReturn=@"NONE";
}
please help!!
thanks in advance.
