react-native - 如何在 React-Native 中检查 Touch ID、Face Id、密码和模式锁定的支持

Question

我已经实现了 react-native-fingerprint-scanner ，它适用于 Touch Id .

现在我想为 添加身份验证两个平台的 Touch ID、Face ID、密码

有什么方法可以检查您的设备是否支持。另外，我尝试使用 react-native-touch-id但它不适用于 Face Id在安卓上。

有没有办法在两个平台(iOS/Android)上实现这一点？

Answer 1

react-native-touch-id应该适用于 TouchID 和 FaceID。

iOS allows the device to fall back to using the passcode, if faceid/touch is not available. this does not mean that if touchid/faceid fails the first few times it will revert to passcode, rather that if the former are not enrolled, then it will use the passcode.

from the docs

您可以先检查它是否受支持。

const optionalConfigObject = {
  fallbackLabel: 'Show Passcode', 
  passcodeFallback: true,
}

TouchID.isSupported(optionalConfigObject)
  .then(biometryType => {
    // Success code
    if (biometryType === 'FaceID') {
        console.log('FaceID is supported.');
    } else {
        console.log('TouchID is supported.');
    }
  })
  .catch(error => {
    // Failure code
    console.log(error);
  });
