TouchId不支持iPhone 7反应母语

Question

我做TouchId认证与反应原生的例子，但是这显示“TouchId不支持”

任何人都一直同样的问题？

我的设备是一个仿真器。但是当我在真实的设备上运行这个问题时，问题是一样的。

有功能

_isSupported = async() => { 
     try { 
      await TouchId.isSupported() 
      Alert.alert('TouchId is supported!') 
     } catch(e) { 
      Alert.alert('TouchId is not supported!') 
     } 
    } 

    _trggerTouchId = async() => { 
     let description = 'Verify the existing mobile phone fingerprint using the home key' 
     //let title  //fallback button title will be default as 'Enter Password'(localized) 
     //let title = "" //fallback button will be hidden 
    let title = "Verify Password" //fallback button title will be 'Verify Password'(unlocalized) 
    try { 
      await TouchId.verify({ 
       description, 
       title, 
      }); 
      //await TouchId.verify("123123123123"); 
      Alert.alert('verify succeeded') 
    } catch(e) { 
      if (e.code == '-3') { 
       //fallback button is pressed 
       Alert.alert('errorCode: ' + e.code + ' verify failed, user wants to ' + title) 
      } 
      else { 
       Alert.alert('errorCode: ' + e.code + ' verify failed') 
      } 
     } 
    }

我有这个问题几个月前得到解决。最后问题出在设备配置和TouchId的权限上。代码很好。
