IOS8获取指纹数据

在IOS8我可以拿指纹数据，并保存或在别的地方使用它，

此代码自主

- (void)authenicateButtonTapped:(id)sender { LAContext *context = [[LAContext alloc] init]; NSError *error = nil; if ([context canEvaluatePolicy:LAPolicyDeviceOwnerAuthenticationWithBiometrics error:&error]) { [context evaluatePolicy:LAPolicyDeviceOwnerAuthenticationWithBiometrics localizedReason:@"Are you the device owner?" reply:^(BOOL success, NSError *error) { if (error) { UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Error" message:@"There was a problem verifying your identity." delegate:nil cancelButtonTitle:@"Ok" otherButtonTitles:nil]; [alert show]; return; } if (success) { UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Success" message:@"You are the device owner!" delegate:nil cancelButtonTitle:@"Ok" otherButtonTitles:nil]; [alert show]; } else { UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Error" message:@"You are not the device owner." delegate:nil cancelButtonTitle:@"Ok" otherButtonTitles:nil]; [alert show]; } }]; } else { UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Error" message:@"Your device cannot authenticate using TouchID." delegate:nil cancelButtonTitle:@"Ok" otherButtonTitles:nil]; [alert show]; } } 

但我不会authentication用户，我不会得到指纹数据，并将此数据发送到服务器端，然后服务器端将检查该指纹数据。

不，您不能读取或保存指纹数据。 即使是苹果公司也不收集这些数据。 您只能使用Touch ID传感器以用户已经保存在系统偏好设置中的指纹解锁您的应用程序。
