我正在使用 Swift 开发一个 iOS 项目。我有简单的登录/注册/丢失密码 View Controller ,以使用 Firebase 实现安全性。问题出在重置密码 View Controller 上。如果用户单击它,它们将被发送(以模式方式呈现)到丢失密码 View Controller 。
当前代码的问题是,当 Firebase 找到输入的电子邮件并发送密码重置电子邮件时,我会显示警报 Controller 以供用户确认。问题是,当我在警报 Controller 上单击“确定”时,我希望重置密码 View Controller 也被关闭。不知道为什么它现在不起作用。我确实收到了电子邮件,但是当我单击警报 Controller 上的“确定”按钮时,它只会关闭警报 Controller ,并且 self.dismissViewControllerAnimated(true,completion: nil)
似乎不会关闭模态提出了重置密码 View Controller 。
我尝试使用self.dismissViewController(true,completion:nil)
以及self.performSegueWithIdentifier(“goToLoginVC”,sender:nil)
。 Non 似乎有效,但我不明白为什么。
这是函数本身:
@IBAction func resetPasswordPressed(sender: AnyObject) {
let email = emailTextField.text
if email != "" {
DataService.ds.REF_BASE.resetPasswordForUser(email, withCompletionBlock: { error in
if error != nil {
// Error - Unidentified Email
showAlert(title: "Unidentified Email Address", msg: "Please, re-enter the email you have registered with.", actionButton: "OK", viewController: self)
} else {
// Success - Sent recovery email
let alertController = UIAlertController(title: "Email Sent", message: "An email has been sent. Please, check your email now.", preferredStyle: UIAlertControllerStyle.Alert)
let okAction = UIAlertAction(title: "OK", style: .Default, handler: nil)
alertController.addAction(okAction)
self.presentViewController(alertController, animated: true, completion: nil)
self.dismissViewControllerAnimated(true, completion: nil)
}
})
} else {
showAlert(title: "Error!", msg: "Email is required in order to reset your password. Please, enter your email. ", actionButton: "OK", viewController: self)
}
}
最佳答案
这样做:
alertController.addAction(UIAlertAction(title: "Ok", style: UIAlertActionStyle. Default, handler: { action in
//Add your logic here
}))
