uni-app使用plus注意事项

isKeyguardSecure

当前设备是否设置密码锁屏

<span style="background-color:#333333"><span style="color:#474747"><code>
<span style="color:#f0e68c"><strong>boolean</strong></span><span style="color:#ffffff"> plus</span><span style="color:#ffffff">.</span><span style="color:#ffffff">fingerprint</span><span style="color:#ffffff">.</span><span style="color:#ffffff">isKeyguardSecure</span><span style="color:#ffffff">();</span></code></span></span>

说明：

如果设备没有设置密码锁屏，则无法使用指纹识别功能，建议调用指纹识别前先使用此接口检查。调用plus.fingerprint.authenticate会返回失败。

参数：

无

返回值：

Boolean : 设备已设置密码锁屏则返回true，否则返回false。

平台支持：

Android (支持) :

要求设置密码锁屏才可以使用指纹识别，如果没有设置密码锁屏应该提示用户进行设置。
iOS (不支持) :
不支持此功能，返回true。

说明：

用户可以开始输入指纹进行识别，如果认证成功则触发successCB回调，识别失败则触发errorCB回调返回错误信息。

参数：

successCB: ( FingerprintSuccessCallback ) 必选 识别认证成功回调

指纹识别操作认证成功时调用。
errorCB: ( FingerprintErrorCallback ) 必选
指纹识别操作认证失败时调用，每次指纹识别错误都会触发一次错误回调。
options: ( AuthenticateOptions ) 可选 识别认证参数
用于设置指纹识别界面显示的提示信息等。

返回值：

void : 无

平台支持：

Android (支持) :

指纹识别过程中不会弹出任何界面，需要开发者根据业务需求弹出提示信息。
iOS (支持) :
指纹识别过程中会弹出系统界面。

常量：

UNSUPPORT: (Number 类型 )不支持指纹识别

当前设备不支持指纹识别功能时返回此错误，错误代码常量值为1。
KEYGUARD_INSECURE: (Number 类型 )设备未设置密码锁屏
当前设备为设置密码锁屏导致无法使用指纹识别功能时返回此错误，错误代码常量值为2。
FINGERPRINT_UNENROLLED: (Number 类型 )未录入指纹识别
当前设备未录入指纹导致无法使用指纹识别功能时返回此错误，错误代码常量值为3。
AUTHENTICATE_MISMATCH: (Number 类型 )指纹识别不匹配
用户指纹识别认证不通过时返回此错误，错误代码常量值为4。用户每次尝试指纹识别认证未通过都会触发此错误，此时还可以继续识别认证。
AUTHENTICATE_OVERLIMIT: (Number 类型 )指纹识别次数超过限制
用户多次指纹识别认证不通过时返回此错误，错误代码常量值为5。通常出现此错误后系统会锁定一段时间禁止使用指纹识别，如果再次调用指纹识别认证会立即返回此错误，因此出现此错误时应该提示用户使用其它方式进行认证。
CANCEL: (Number 类型 )取消指纹识别
用户取消指纹识别认证时返回此错误，错误代码常量值为6。
UNKNOWN_ERROR: (Number 类型 )未知错误
其它未知错误，错误代码常量值为7。

属性：
