_ [Swift] presentedViewController→present

present(controller!,animated: false, completion:nil)

らしい。ここでも変わった。

_ [Swift] WebSite読み出し

これも変わった。

import UIKit
import Foundation
import PlaygroundSupport

var urlString = "https://www.apple.com"
var url = NSURL(string: urlString)
var request = NSURLRequest(url: url! as URL)

let config = URLSessionConfiguration.default
let session = URLSession(configuration: config)
let task = session.dataTask(with: url! as URL,
                                  completionHandler: {data, response, error in
                                   print(NSString(data: data!,encoding: String.Encoding.utf8.rawValue) ?? "")
})
task.resume() 
PlaygroundPage.current.needsIndefiniteExecution = true

_ [Swift] WebサイトのXML解析

ここでも変わった。

import Foundation

class MyParserDelegate : NSObject, XMLParserDelegate{
   var isTitle = false
   func parser(_ parser: XMLParser,
               didStartElement elementName: String,
                               namespaceURI: String?,
                               qualifiedName qName: String?,
                               attributes attributesDict: [String : String]
       )
   {
       if (elementName == "title"){
           print("タイトル:")
          
           isTitle = true
       }
   }
   private func parser(parser: XMLParser,
               foundCharacters string: String){
       if (isTitle){
           print(string)
       }
   }
   private func parser(parser: XMLParser,
               didEndElement elementName: String,
                             namespaceURI: String?,
                             qualifiedName qName: String?){
       if (elementName == "title"){
           print("\n")
           isTitle = false
       }
   }
   
}

var urlString = "http://rss.dailynews.yahoo.co.jp/fc/rss.xml"
var url = NSURL(string: urlString)
var parser = XMLParser(contentsOf: url! as URL)
var delegate = MyParserDelegate()
parser?.delegate = delegate
parser?.parse()
