static func fingerprint(callBack:(isSuccess: Bool?) -> ()) {
let context = LAContext()
let can = context.canEvaluatePolicy(.DeviceOwnerAuthentication, error: nil)
guard can == true else {
callBack(isSuccess: nil)
return //不可用
}
context.evaluatePolicy(.DeviceOwnerAuthentication, localizedReason: "打个卡") { (success, error) in

使用
Validation.fingerprint{ (isSuccess) in
print(isSuccess) // true 成功 false 失败 nil 不可用
