Ios 当我从另一个视图中退出时，触摸Id自动触发成功

这个过程是： 1使用触摸id登录的用户 2用户退出（退出退出退出登录） 然后，应用程序autotrigger touch id和成功响应（模拟器中不会出现这种情况）帮助

这是我登录viewcontroller时的侦听器

override func viewWillAppear(_ animated: Bool) {
    super.viewWillAppear(animated)      

    if authenticationContext.canEvaluatePolicy(.deviceOwnerAuthenticationWithBiometrics, error: &error) && DataContainerSingleton.sharedDataContainer.fingerPrintEnabled == "SI"{
        self.touchIdListener()
    }


}

因此，解决办法是改变现状

self.dismiss(animated: true, completion: nil)

例如

var storyboard = UIStoryboard()
            let vc : LoginViewController
            if (Constants.IS_IPAD) {
                storyboard = UIStoryboard.init(name: "LoginIpad", bundle: nil)
                vc = storyboard.instantiateViewController(withIdentifier: "ipadViewController") as! LoginViewController
            } else {
                storyboard = UIStoryboard.init(name: "Login", bundle: nil)
                vc = storyboard.instantiateViewController(withIdentifier: "iphoneViewController") as! LoginViewController
            }
            let navigationController = UINavigationController(rootViewController: vc)
            self.present(navigationController, animated: true, completion: nil)

var storyboard = UIStoryboard()
            let vc : LoginViewController
            if (Constants.IS_IPAD) {
                storyboard = UIStoryboard.init(name: "LoginIpad", bundle: nil)
                vc = storyboard.instantiateViewController(withIdentifier: "ipadViewController") as! LoginViewController
            } else {
                storyboard = UIStoryboard.init(name: "Login", bundle: nil)
                vc = storyboard.instantiateViewController(withIdentifier: "iphoneViewController") as! LoginViewController
            }
            let navigationController = UINavigationController(rootViewController: vc)
            self.present(navigationController, animated: true, completion: nil)
