ios - 没有iPhone 5s设备时如何测试Touch ID功能

Question

我想在应用程序中实现触摸ID功能，为此我编写了代码:

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];

        }

我没有支持触摸ID功能的设备，因此在哪里可以对其进行测试以查看其功能是否正常。

任何帮助，将不胜感激。谢谢。

您只能在真实设备上测试TouchID。模拟器不支持此功能。
