在检查用户通过身份验证时，performSegue无法正常运行FireBase 3/4 [英] performSegue not working FireBase while checking the user is authenticated Swift 3/4

问题描述

我刚刚完成了一个letsbuildthatapp的教程视频，内容是关于Firebase与社交登录的混合.

I just finish a tutorial video of letsbuildthatapp about firebase mixed with social login.

如果用户已经通过身份验证，我目前正尝试执行segue.

I currently trying to perform a segue if the user is already authenticated.

如果和正在与我认识的segue进行segue之后，我会在我的东西上打印一些东西，因为我正在使用它进行测试.

I print something in my if and just after I performSegue with a segue who I know work because I'm using it for a test.

有我的代码

func verifDejaConnecter() {
    if Auth.auth().currentUser?.uid != nil {
        performSegue(withIdentifier: "segueAccueilToPres", sender: nil)
        print("test")
    } else {
        return
    }
}

mySegue已创建并可以正常工作，但此处未添加任何内容.

mySegue is created and works but nothing append here.

在控制台中，我可以在if ...中看到打印结果，但没有任何变化

In the console I can see the test resulting from the print in the if ... but nothing is mooving

推荐答案

尝试一下:

func verifDejaConnecter() {
  if Auth.auth().currentUser?.uid != nil {
    DispatchQueue.main.async {
      self.performSegue(withIdentifier: "segueAccueilToPres", sender: self)
        print("test")
    }
  } else {
    return
  }
}
