该文章介绍了如何在iOS应用中实现发送邮件的功能，使用MFMailComposeViewController进行邮件发送，并处理发送结果。同时，文章也讨论了两种拨打电话的方法，包括直接拨打和通过WKWebView，以及它们对应用行为的影响。

发送邮件

1、引入头文件

import MessageUI

2、发送邮件

   func sendMail(_ email: String) {
        if #available(iOS 13.0, *) {
            if (MFMailComposeViewController.canSendMail() == true) {
                let mailComposer = MFMailComposeViewController()
                mailComposer.mailComposeDelegate = self
                mailComposer.setToRecipients([email]) /// 收件人
                mailComposer.setCcRecipients([""]) /// 抄送
                mailComposer.setBccRecipients([""]) /// 密送
                mailComposer.setSubject("") /// 主题
                mailComposer.setMessageBody("", isHTML: false) /// 内容
                self.present(mailComposer, animated: true)
            }
        }else {
            let url: NSURL = NSURL(string: email) ?? NSURL()
            if (UIApplication.shared.canOpenURL(url as URL) == true) {
                UIApplication.shared.open(url as URL, options: [:], completionHandler: nil)
            }
        }
    }

3、实现代理MFMailComposeViewControllerDelegate、UINavigationControllerDelegate

extension ViewController: MFMailComposeViewControllerDelegate, UINavigationControllerDelegate {
    func mailComposeController(_ controller: MFMailComposeViewController, didFinishWith result: MFMailComposeResult, error: Error?) {
        switch result {
        case .cancelled:
            print("取消发送")
        case .saved:
            print("保存草稿文件")
        case .sent:
            print("发送成功")
        case .failed:
            print("发送失败")
        default:
            break
        }
        self.dismiss(animated: true, completion: nil)
    }
}

打电话

1、拨打完电话回不到原来的应用，会停留在通讯录里，直接拨打，不弹出提示

let url: NSURL = NSURL(string: "tel:" + telephone)!
UIApplication.shared.open(url as URL, options: [:], completionHandler: nil)

2、打完电话后还会回到原来的程序，也会弹出提示

let url: NSURL = NSURL(string: "tel:" + telephone)!
let urlRequest = URLRequest(url: url as URL, cachePolicy: .reloadIgnoringCacheData, timeoutInterval: 30)
let webView = WKWebView()
webView.load(urlRequest)
self.view.addSubview(webView)

3、打完电话后还会回到原来的程序，也会弹出提示

let url: NSURL = NSURL(string: "telprompt://" + telephone)!
UIApplication.shared.open(url as URL, options: [:], completionHandler: nil)
