preface

Clubhouse is a new social networking application that provides real-time audio chat and interaction, creating the possibility for users to break down the barriers of information dissemination and interpersonal connection caused by social barriers. Clubhouse, often nicknamed “Silicon Valley’s Hottest start-up,” markets itself as an “exclusive” and “alternative” social network that attracts a variety of celebrities and people who just want to talk to each other.

Create rooms and add topics

  • Create room logic:
    @IBAction func didClickTopicButton(_ sender: Any) {
        passwordTextField.resignFirstResponder()
        let alertVc = ARAlertTextViewController(title: "Add topic\n ", message: "Like funny things that happen around you.", preferredStyle: .alert)
        alertVc.updateTextView(text: topic)
        let cancelAction =  UIAlertAction (title:  "Cancel" , style: .cancel , handler:  nil )
        let okAction =  UIAlertAction (title:  "Set the topic" , style: . default , handler: {
                action  in
            if !self.stringAllIsEmpty(string: alertVc.textView.text) {
                self.topic = alertVc.textView.text ?? ""
                self.updateTopic()
            }
        })
        alertVc.addAction(cancelAction)
        alertVc.addAction(okAction)
        present(alertVc, animated: true, completion: nil)
        DispatchQueue.main.asyncAfter(deadline: DispatchTime.now() + 0.1) {
            alertVc.textView.becomeFirstResponder()
        }
    }
    
    func updateTopic(a) {
        if isPrivate = = 0 {
            (topic.count = = 0) ? (topicLabel.text = publicText) : (topicLabel.text = String(format: "% @ :" % @ "", publicText,topic))
        } else {
            (topic.count = = 0) ? (topicLabel.text = passwordText) : (topicLabel.text = String(format: "% @ :" % @ "", passwordText,topic))
        }
    }
    
    @IBAction func didClickButton(_ sender: UIButton) {
        if sender.tag ! = isPrivate {
            isPrivate = sender.tag
            passwordTextField.resignFirstResponder()
            updateTopic()
            if isPrivate = = 0 {
                / / public
                passwordView.isHidden = true

                passwordView.isHidden = false
                padding.constant = 47
                passwordButton.backgroundColor = UIColor(hexString: "#DFE2EE")

            }
