Firebase 和 Swift 的重置密码问题

Question

Firebase 更新了后端后，我遇到了重置密码的问题。由于某种原因，该应用程序崩溃了（即使它发送了带有重置密码的电子邮件）。这是我得到的控制台错误：

2016-06-04 12:32:21.883 NewApp[47459:27055361] *** Assertion failure in -[UIKeyboardTaskQueue waitUntilAllTasksAreFinished], /BuildRoot/Library/Caches/com.apple.xbs/Sources/UIKit_Sim/UIKit-3512.60.7/Keyboard/UIKeyboardTaskQueue.m:386
2016-06-04 12:32:21.890 NewApp[47459:27055361] *** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: '-[UIKeyboardTaskQueue waitUntilAllTasksAreFinished] may only be called from the main thread.'
libc++abi.dylib: terminating with uncaught exception of type NSException

在 ResetPasswordVC 中，我有以下内容：

 @IBAction func resetPasswordTapped(sender: ButtonWhite) {

    SVProgressHUD.showWithStatus("Please, wait...")
    SVProgressHUD.setDefaultMaskType(.Gradient)

    let email = emailTextField.text

    if email != "" {

        FIRAuth.auth()?.sendPasswordResetWithEmail(email!, completion: { (error) in

            if error != nil {

                // Error - Unidentified Email
                SVProgressHUD.dismiss()
                showAlert(title: "Unidentified Email Address", msg: "Please, re-enter the email you have registered with.", actionButton: "OK", viewController: self)

            } else {

                // Success - Sent recovery email

                SVProgressHUD.dismiss()

                let alertController = UIAlertController(title: "Email Sent", message: "An email has been sent. Please, check your email now.", preferredStyle: .Alert)
                alertController.addAction(UIAlertAction(title: "OK", style: .Default, handler: { action in

                    self.dismissViewControllerAnimated(true, completion: nil)
                }))
                self.presentViewController(alertController, animated: true, completion: nil)
            }

        })

    } else {

        SVProgressHUD.dismiss()
        showAlert(title: "Error!", msg: "Email is required in order to reset your password. Please, enter your email. ", actionButton: "OK", viewController: self)
    } 
}

我用断点对其进行了测试以查看流程，它到达 FIRAuth.auth()?.sendPasswordResetWithEmail(email!, completion: { (error) in 电子邮件具有值的位置，它应该根据它 if/else 语句执行一些检查，但它没有。

我不知道为什么。该代码正在运行（发送密码恢复电子邮件），但该应用程序因该错误而崩溃。线索？

我找到了问题和解决方案。出于某种原因，问题在线程中。这解决了它：

            FIRAuth.auth()?.sendPasswordResetWithEmail(email!, completion: { (error) in


            NSOperationQueue.mainQueue().addOperationWithBlock {

            if error != nil {

                // Error - Unidentified Email
                SVProgressHUD.dismiss()
                showAlert(title: "Unidentified Email Address", msg: "Please, re-enter the email you have registered with.", actionButton: "OK", viewController: self)

            } else {

                // Success - Sends recovery email

                SVProgressHUD.dismiss()

                let alertController = UIAlertController(title: "Email Sent", message: "An email has been sent. Please, check your email now.", preferredStyle: .Alert)
                alertController.addAction(UIAlertAction(title: "OK", style: .Default, handler: { action in

                    self.dismissViewControllerAnimated(true, completion: nil)
                }))
                self.presentViewController(alertController, animated: true, completion: nil)
            }

            }})
