• Disable button2 if button1 is not clicked

  I want to disable the button2 if button1 is not clicked, and enable it when button1 is clicked. The problem is, the button2 is disable even I already clicked the button1. I don't receive any error, I'm using Swift4 in Xcode10.

  Here is my code:

  class ViewController: UIViewController {
  
    @IBOutlet weak var btn1: UIButton!
    @IBOutlet weak var btn2: UIButton!
  
    override func viewDidLoad() {
       super.viewDidLoad()
  
       intro()
  
       btn1.setImage(UIImage(named: "checked.png"), for: .selected)
       btn1.setImage(UIImage(named: "unchecked.png"), for: .normal)
    }
  
    @IBAction func button1(_ sender: UIButton) {
       UIView.animate(withDuration: 0.5, delay: 0.1, options: .curveLinear, animations: {
          sender.transform = CGAffineTransform(scaleX: 0.1, y: 0.1)
      }) { (success) in
       UIView.animate(withDuration: 0.5, delay: 0.1, options: .curveLinear, animations: {
              sender.isSelected = !sender.isSelected
              sender.transform = .identity
          }, completion: nil)
        }
     }
  
  
  
     func intro() {
        if btn1.isSelected == true {
          btn2.isUserInteractionEnabled = true
        } else {
          btn2.isUserInteractionEnabled = false
        }
     }
  
  }
  

  I also tried this code:

  func intro() {
      if btn1.isTouchInside == true {
        btn2.isUserInteractionEnabled = true
      } else {
        btn2.isUserInteractionEnabled = false
      }
    }

• How to get the return value of the callback function from a request which is exported as a module

  I'm trying to parse the names and birthdays of all the presidents of USA. First I get all the urls. I have previously exported a module in which I am trying to return an object containing the name and birthday of the president, by calling a request using the URL. I am unable to retrieve the data in the main js file.

  I am trying to do this without using promises.

  The module I am exporting :

  
  const request = require('request'); //to make HTML requests
  const cheerio = require('cheerio');
  
  const POTUSParse = function(url){
     return request(url,(error,response,HTML) => {
      if(!error && response.statusCode == 200){
          const $ = cheerio.load(HTML);
          const presidentName = $("#firstHeading").text();
          const bdayString = $(".bday").text();
  
          return {
              "name" : presidentName,
              "bday" : bdayString
          };
      }
     });
  
  }
  
  
  module.exports = POTUSParse;
  
  
  
  

  The main JS file :

  const POTUSParse = require('./getName&BDAYModule');
  const request = require('request');
  const cheerio = require('cheerio');
  
  
  request("https://en.wikipedia.org/wiki/List_of_Presidents_of_the_United_States",(error,response,html) => {
      if(error || response.statusCode != 200){
          return;
      }
  
      const wikiURLs = [];
      const $ = cheerio.load(html);
      $("big a").each((index,rawDOMElement) => {
          wikiURLs.push($(rawDOMElement).attr("href"));
      });
  
      for(var i=0;i<wikiURLs.length;i++){
          console.log(POTUSParse("https://en.wikipedia.org" + wikiURLs[i]));
      }
  });
  
  

  I am getting an object which the request module returns. How can I get the return value of the callback function ?
• Error in plugin "gulp-shell" during testing Hyperledger Fabric Client SDK for Node.js

• LetsEncrypt SSL certificate creation failed for subdomain when transferring site

  I am moving a website from server A to server B (Windows Server + IIS).

  Server A has site.com and sub.site.com A-records pointing to IPs on server A. Now I am trying to keep the DNS on server A while pointing the A records to IPs on server B.

  I managed to create site.com SSL certificate using LetsEncrypt win-acme client but sub.site.com fails with following output:

  [INFO] Target generated using plugin IISBinding: sub.site.com
  [WARN] First chance error calling into ACME server, retrying with new nonce...
  [INFO] Authorize identifier: sub.site.com

  [EROR] Authorization result: invalid

  It worked with site.com, what am I doing wrong?

  I don't even know what that .well-known/acme-challenge directory is, there isn't one on my server (not for site.com root dir either).
