如何在没有 iPhone 5s 设备的情况下测试 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 touch id 功能的设备，所以我可以在哪里测试它，看看它的功能是否正常工作。

如有任何帮助，我们将不胜感激。谢谢

您只能在真实设备上测试 TouchID。模拟器不支持这个
