앱 12개를 만들며 배우는 Swift4 & iOS11 아이폰 iOS 개발 강좌 - 인프런

주요 내용

• Single View App > MiniBrowser 프로젝트 만들기

Main.storyboard

• Segment Control 추가 > Segment : 4개 > 각 segment 이름 바꾸기
• 상단에 text View, 하단에 tool bar 추가 > tool bar에 bar button 4개 추가 > flexible space bar button을 끝과 사이에 각각 (총 6개) 추가 (정렬 효과) 
• bar button > system item : rewind / fast forward / stop / refresh로 각각 추가
• webkit view 가운데 화면에 추가
• activity indicator view 추가

viewController.swift

• bookMarkAction 추가
• class에 UITextFieldDelegate 추가 > main.storyboard 에서 viewController에 연결 (나 자신에게 연결)
• textFieldShouldReturn 추가 > https:// 없어도 이동 가능하도록 추가
• WKNavigationDelegate 참고

완성 예시

코드

1) ViewController.swift

import UIKit
import WebKit

class ViewController: UIViewController, UITextFieldDelegate, WKNavigationDelegate {
    @IBOutlet weak var bookMarkSegmentedControl: UISegmentedControl!
    @IBOutlet weak var urlTextField: UITextView!
    @IBOutlet weak var mainWebView: WKWebView!
    @IBOutlet weak var spinningActivityIndicator: UIActivityIndicatorView!
    
    override func viewDidLoad() {
        super.viewDidLoad()
        
        let initialURL = "https://www.facebook.com"
        let myURL = URL(string:initialURL)
        let myRequest = URLRequest(url:myURL!)
        mainWebView.load(myRequest)
        urlTextField.text = initialURL
        mainWebView.navigationDelegate = self
    }
    
    func webView(_ webView: WKWebView, didStartProvisionalNavigation navigation: WKNavigation!) {
        spinningActivityIndicator.startAnimating()
    }
    func webView(_ webView: WKWebView, didFinish navigation: WKNavigation!) {
        spinningActivityIndicator.stopAnimating()
    }
    

    @IBAction func bookMarkAction(_ sender: Any) {
        let bookMarkURL = bookMarkSegmentedControl.titleForSegment(at: bookMarkSegmentedControl.selectedSegmentIndex)
        let urlString = "https://www.\(bookMarkURL!).com"
        mainWebView.load(URLRequest(url: URL(string:urlString)!))
        urlTextField.text = urlString
    }
    
    func textFieldShouldReturn(_ textField: UITextField) -> Bool {
        var urlString = "\(urlTextField.text!)"
        if !urlString.hasPrefix("https://") {
            urlString = "https://\(urlTextField.text!)"
        }
        
        urlTextField.text = urlString
        mainWebView.load(URLRequest(url: URL(string:urlString)!))
        textField.resignFirstResponder()
        return true
    }
    
    @IBAction func goBackAction(_ sender: Any) {
        mainWebView.goBack()
    }
    @IBAction func goForwardAction(_ sender: Any) {
        mainWebView.goForward()
    }
    @IBAction func stopLoadingAction(_ sender: Any) {
        mainWebView.stopLoading()
    }
    @IBAction func reloadAction(_ sender: Any) {
        mainWebView.reload()
    }
