iOS开发中Swift 指纹验证功能模块实例代码

本文给大家分享ios调用touchid代码块，非常不错，具有参考借鉴价值，需要的朋友参考下把

iOS调用TouchID代码:

									override func viewDidLoad() {

									   super.viewDidLoad()

									   let context = LAContext()

									   var error: NSError? = nil

									   let canEvaluatePolicy = context.canEvaluatePolicy(LAPolicy.deviceOwnerAuthenticationWithBiometrics, error: &error) as Bool

									   if error != nil {

									     print(error!.localizedDescription as String)

									   }

									   if canEvaluatePolicy {

									     print("有指纹验证功能")

									     context.evaluatePolicy(LAPolicy.deviceOwnerAuthenticationWithBiometrics, localizedReason: "放上您的狗爪", reply: { (success: Bool, error: Error?) in

									       if success {

									         print("验证成功")

									       } else {

									         print("验证失败: \(error?.localizedDescription)")

									       }

									     })

									   } else {

									     print("还没开启指纹验证呢")

									   }

									 }
