Question

if (PFUser.currentUser() == nil) {

        self.logInViewController.fields = PFLogInFields.UsernameAndPassword | PFLogInFields.LogInButton | PFLogInFields.SignUpButton | PFLogInFields.PasswordForgotten | PFLogInFields.DismissButton

        var logInLogoTitle = UILabel()
        logInLogoTitle.text = "Cinderella"

        self.logInViewController.PFLoginview.logo = logInLogoTitle //error: could not find member 'logo'

        self.logInViewController.delegate = self

        var signUpLogoTitle = UILabel()
        signUpLogoTitle.text = "Cinderella"

        self.signUpViewController.PFSignUpView.logo = signUpLogoTitle // error: could not find member 'logo'

        self.signUpViewController.delegate = self

        self.logInViewController.signUpController = self.signUpViewController


    }

我还是初学者，不知道这个错误意味着什么.. 有人可以帮我解决问题吗？

您使用的是课程PFLoginview，而不是属性logInView，您可以更改为徽标，如下所示

self.logInViewController.logInView.logo = logInLogoTitle
