【问题描述】：

我有一个代码，允许我从应用程序发送电子邮件消息。如何获取手机型号和ios版本数据..我是SwiftUi的新用户，不胜感激。

请参阅屏幕截图中的示例 Example in the picture

这是我的代码

import Foundation
import SwiftUI
import MessageUI

struct MailView: View 
@State private var showingMail = false

var body: some View 
    VStack 
        Button("Open Mail") 
            self.showingMail.toggle()
        
    
    .sheet(isPresented: $showingMail) 
        MailComposeViewController(toRecipients: [""], mailBody: "Here is mail body") 
            // Did finish action
        
    





struct MailComposeViewController: UIViewControllerRepresentable 

var toRecipients: [String]
var mailBody: String

var didFinish: ()->()

func makeCoordinator() -> Coordinator 
    return Coordinator(self)


func makeUIViewController(context: UIViewControllerRepresentableContext<MailComposeViewController>) -> MFMailComposeViewController 
    
    let mail = MFMailComposeViewController()
    mail.mailComposeDelegate = context.coordinator
    mail.setToRecipients(self.toRecipients)
    mail.setMessageBody(self.mailBody, ishtml: true)
    
    return mail


final class Coordinator: NSObject, MFMailComposeViewControllerDelegate 
    
    var parent: MailComposeViewController
    
    init(_ mailController: MailComposeViewController) 
        self.parent = mailController
    
    
    func mailComposeController(_ controller: MFMailComposeViewController, didFinishWith result: MFMailComposeResult, error: Error?) 
        parent.didFinish()
        controller.dismiss(animated: true)
    


func updateUIViewController(_ uiViewController: MFMailComposeViewController, context: UIViewControllerRepresentableContext<MailComposeViewController>) 
    

【参考方案1】：

你可以这样做

struct ContentView: View 
    
    var systemVersion = UIDevice.current.systemVersion
    var device = UIDevice.current.name
    
      var body: some View 
        VStack 
            Text("iOS Version: \(systemVersion)")
            Text("Device: \(device)")

【讨论】：

你知道如何在我的示例代码中换行写文本吗？ .sheet(isPresented: $showingMail) MailComposeViewController(toRecipients: ["[e-mail]"], mailBody:"iOS Version: \(systemVersion) Device: \(device) " )

@DenisMel 你可以像这样在"iOS Version: \(systemVersion) \nDevice: \(device)"之间添加\n
