Firebase iOS 身份验证 - 执行 segue

Question

我目前正在向我的 iOS 应用程序添加 Firebase 身份验证。我可以注册并登录用户，但是，我很难找到可以添加转场以进入下一个屏幕的位置。

func signInUser(email: String, password: String){
    // creates user with the firebase autenthication platform
    Auth.auth().signIn(withEmail: email, password: password) { [weak self] authResult, error in
        guard let strongSelf = self else { return }
    }
    
    // would the segue go here?
}

Answer 1

您应该在 signIn 函数完成处理程序中执行您的代码：

func signInUser(email: String, password: String){
    //creates user with the firebase autenthication platform
    Auth.auth().signIn(withEmail: email, password: password) { [weak self] authResult, error in
        guard let strongSelf = self else { return }

        if let error = error as? NSError {
            // Handle sign in error
            switch AuthErrorCode(error.code) {
                ...
            }
        } else {
            // No errors: Perform segue here...
        }
    }
}
