饅頭的備忘錄

這是最單純在SwiftUI上開啟WebView的範例 import SwiftUI import WebKit struct ContentView : View {     var body: some View {         VStack {             WebView(request: URLRequest(url: URL(string: "https://tw.news.yahoo.com/politics")!))         }.navigationBarTitle("Speed Test")     } } struct WebView: UIViewRepresentable {     let request: URLRequest         func makeUIView(context: Context) -> WKWebView {         return WKWebView()     }         func updateUIView(_ uiView: WKWebView, context: Context) {         uiView.load(request)     } } struct Speed_Test_Previews: PreviewProvider {     static var previews: some View {         Speed_Test()     } }

之後會把一些我常用的 Swift 5 的範例放過來 免得找到了又忘了 這是 Xcode 11 & Swift 5 & IOS 13 的環境的東西 因為主要是SwiftUI的改變  所以有個 SwiftUI 的標頭 找到整份完整的程式  一個簡單小範例 import SwiftUI import CoreImage struct ContentView: View {     let qrCodeString = "BEGIN:VCARD \n" +     "VERSION:2.1 \n" +     "FN:John Peter \n" +     "N:Peter;John \n" +     "TITLE:Admin \n" +     "TEL;CELL:+91 431 524 2345 \n" +     "TEL;WORK;VOICE:+91 436 542 8374 \n" +     "EMAIL;WORK;INTERNET:John@ommail.in \n" +     "URL:www.facebook.com \n" +     "URL: www.instagram.com \n" +     "ADR;WORK:;;423 ofce sales Center;Newark;DE;3243;USA \n" +     "ORG:xxx Private limited \n" +     "END:VCARD"     var body: some View {         Image(uiImage: generateQRCode(from: qrCodeString)!)     }         func generateQRCode(from string: Stri...
