将动作添加到标准文本库UIBarButtonItem

Question

[我相信我已经遵循了其他SO线程的步骤，当敲击UIBarButtonItem时通过另一种方法来调用动作，但是我不断收到以下错误Argument of '#selector' does not refer to an '@objc' method, property, or initializer，并且该错误突出显示了#selector文本。] >

这是设置按钮：

navigationItem.rightBarButtonItem = UIBarButtonItem(title: "\(barButtonItemText)", style: .done, target: self, action: #selector(inviteMethod(inviteMethod: inviteMethodSelected!)))
这是在点击按钮时我试图运行的方法：

    func inviteMethod (inviteMethod:String) {

    let inviteMethod = inviteMethod

    if inviteMethod == "email" {
        inviteViaEmail(invitedContacts: self.invitedContacts)
    }
    else {
        inviteViaText(invitedContacts: self.invitedContacts)  
    }  }
如果有帮助，可以使用其中一种邀请方法的示例

    func inviteViaEmail (invitedContacts:[Contact]) {

    var invitedContactsEmails:[String] = []

    for contactEmails in invitedContacts {

        let emailAddress = contactEmails.emailAddress ?? ""

        invitedContactsEmails.append(emailAddress)

    }

        let mc = MFMailComposeViewController()
        mc.mailComposeDelegate = self as? MFMailComposeViewControllerDelegate

        mc.setToRecipients(invitedContactsEmails)
    mc.setSubject("Invite for Gallery App, Event \(event?.eventName)")

    mc.setMessageBody("This is a test invite email \n\n\(event?.eventHost) has invited you to join their event", isHTML: false)

        self.present(mc, animated: true, completion: nil)

}
