Firebase注销不在Swift中工作 [英] Firebase sign out not working in Swift

问题描述

我使用最新的Firebase API（3.2.1），并使用此代码检查用户是否已登录：

  override func viewDidAppear（animated：Bool）{
 super.viewDidAppear（animated）
 $ b $ if（self.navigationController！= nil）{
 self.navigationController！.setNavigationBarHidden true，animated：true）
 
 $ b $ if（FIRAuth.auth（）！= nil）{
 self.performSegueWithIdentifier（loginSuccessSegue，sender：self）
} 
} 
  

换句话说，如果auth对象存在，我切换到其他控制器。在该控制器上，我已经注销了正在签名的按钮，如下所示：

  do {
 try FIRAuth.auth （）？。signOut（）
 self.performSegueWithIdentifier（logoutSegue，sender：self）
} catch {
 print（签出时出错！）
} 
  

我不会在这个操作中遇到错误，但是当我切换到登录控制器时，这个验证对象是存在的然后我再次切换回控制器的数据。我也尝试在auth中检查当前的用户对象，它是存在的和有效的。

任何人都知道我是如何正确地签出？

试试看！ FIRAuth.auth（）！。signOut（）

这是我在IBAction中的代码，它工作得很好：

 尝试！ FIRAuth.auth（）！。signOut（）
 if let storyboard = self.storyboard {
 let vc = storyboard.instantiateViewControllerWithIdentifier（firstNavigationController）as！ UINavigationController 
 self.presentViewController（vc，animated：false，completion：nil）
} 
  

I am using newest Firebase API (3.2.1) and I am using this code to check if user is signed in:

override func viewDidAppear(animated: Bool) {
    super.viewDidAppear(animated)

    if(self.navigationController != nil){
        self.navigationController!.setNavigationBarHidden(true, animated: true)
    }

    if(FIRAuth.auth() != nil){
        self.performSegueWithIdentifier("loginSuccessSegue", sender: self)
    }
}

In other words if auth object is present I am switching to other controller. On that controller I have sign out button which is doing sign out like this:

do{
    try FIRAuth.auth()?.signOut()
    self.performSegueWithIdentifier("logoutSegue", sender: self)
}catch{
    print("Error while signing out!")
}

I do not get error on this operation but when I am switched to login controller, this auth object is present and I get switched back again to controller with data. I also tried checking the current user object in auth and it is present and valid.

Anyone knows how an I properly do sign out?

解决方案

try using :

try! FIRAuth.auth()!.signOut()

This is the code I have in an IBAction, and it's working just fine :

try! FIRAuth.auth()!.signOut()     
if let storyboard = self.storyboard {
    let vc = storyboard.instantiateViewControllerWithIdentifier("firstNavigationController") as! UINavigationController
        self.presentViewController(vc, animated: false, completion: nil)
    }
