打电话

• 都会弹框提示用户

• 第一种方式

let url = URL(string: "tel://10010")
 UIApplication.shared.openURL(url!)

• 第二种方式
  • 注意：属于私有api，可能会被拒

   let url = URL(string: "telprompt://10010")
   UIApplication.shared.openURL(url!)

• 第三种方式
  • 必须要添加到视图上，不然没有反应
  • 不要设置frame，否则会出现遮挡问题

let url = URL(string: "tel://10010")
let webView = UIWebView()
        webView.loadRequest(URLRequest(url: url!))
        view.addSubview(webView)

发短信

// 跳转到发短信页面，但是无法指定发短信的内容，只能指定一个发送的对象
let url = URL(string: "sms://10010")
        UIApplication.shared.openURL(url!)

import MessageUI

// 跳转到发短信页面，指定发送内容，可以指定多个发送的对象，发送之后有结果回掉
override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
        
        // 短信控制器
        let MCVC = MFMessageComposeViewController()
        /// 短信内容
        MCVC.body = "短信内容"
//        代理
        MCVC.messageComposeDelegate = self
//        收件人列表
        MCVC.recipients = ["10010", "10086"]
        self.present(MCVC, animated: true, completion: nil)
    }

extension ViewController : MFMessageComposeViewControllerDelegate {
    func messageComposeViewController(_ controller: MFMessageComposeViewController, didFinishWith result: MessageComposeResult) {
        /// 返回短信界面
        controller.dismiss(animated: true, completion: nil)
        
        switch result {
        case .cancelled:
            print("取消发送")
        case .sent:
            print("已经发送")
        case .failed:
            print("发送失败")
        }
        
    }
}

let url = URL(string: "mailto://10010@qq.com")
        UIApplication.shared.openURL(url!)

import MessageUI

    override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
        let MCVC = MFMailComposeViewController()
        /// 内容
        MCVC.setMessageBody("邮箱内容", isHTML: false)
        //        代理
        MCVC.mailComposeDelegate = self
        //        收件人列表
        MCVC.setToRecipients(["10010@qq.com","10086@qq.com"])
        self.present(MCVC, animated: true, completion: nil)
    }

}

extension ViewController : MFMailComposeViewControllerDelegate {
    func mailComposeController(_ controller: MFMailComposeViewController, didFinishWith result: MFMailComposeResult, error: Error?) {
        controller.dismiss(animated: true, completion: nil)
        switch result {

let url = URL(string: "cool:com.test.b")
        UIApplication.shared.openURL(url!)

B中的操作

应用评分

• 模拟器没反应，使用真机

let appID = "1338674422"
        let url = URL(string: "itms-apps://itunes.apple.com/cn/app/id\(appID)?mt=8")
        UIApplication.shared.openURL(url!)
