ios - Xcode swift : Could not find member

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


    }

我还是个初学者，不确定这个错误是什么意思..谁能帮我解决这个问题？

Answer 1

您正在使用类 PFLoginview 而不是属性 logInView 您可以更改为如下 Logo

self.logInViewController.logInView.logo = logInLogoTitle
