Question

首先，我真的很惊讶这不是重复，因为在Objective-C中有很多堆栈溢出问题可以解决这个问题，但是我还没有看到使用Swift的好答案。 / p>

我正在寻找的是Swift中的代码片段，它将任意字符串作为文本消息的正文发送到给定的电话号码。从本质上讲，我喜欢Apple官方文档中的this，但是使用Swift而不是Objective-C。

我认为这并不困难，因为它可以在Android中的几行代码中完成。

编辑：我正在寻找的是5-20行Swift代码，我不同意这个太宽泛。在Java（适用于Android）中，解决方案如下所示：

package com.company.appname;
import android.app.Activity;
import android.telephony.SmsManager;
public class MainActivity extends Activity {
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        public static final mPhoneNumber = "1111111111";
        public static final mMessage = "hello phone";
        SmsManager.getDefault().sendTextMessage(mPhoneNumber, null, mMessage, null, null);
     }
}

现在这是Android解决方案，它只有11行。 Java往往比Swift更冗长，所以我怀疑我提出的问题是“太宽泛”＃34，我更不可能知道如何使用Objective-C MessageComposer对象，因为我在上面链接的文档在Swift中的用法不清楚。

不确定你是否真的得到了答案。我正在进行类似的搜索并遇到了这个解决方案，并让它发挥作用。

import UIKit
import MessageUI

class ViewController: UIViewController, MFMessageComposeViewControllerDelegate {

    @IBOutlet weak var phoneNumber: UITextField!

    override func viewDidLoad() {
        super.viewDidLoad()
    }

    @IBAction func sendText(sender: UIButton) {
        if (MFMessageComposeViewController.canSendText()) {
            let controller = MFMessageComposeViewController()
            controller.body = "Message Body"
            controller.recipients = [phoneNumber.text]
            controller.messageComposeDelegate = self
            self.presentViewController(controller, animated: true, completion: nil)
        }
    }

    func messageComposeViewController(controller: MFMessageComposeViewController!, didFinishWithResult result: MessageComposeResult) {
        //... handle sms screen actions
        self.dismissViewControllerAnimated(true, completion: nil)
    }

    override func viewWillDisappear(animated: Bool) {
        self.navigationController?.navigationBarHidden = false
    }
}

Swift 3.0解决方案：

func sendSMSText(phoneNumber: String) {
        if (MFMessageComposeViewController.canSendText()) {
            let controller = MFMessageComposeViewController()
            controller.body = ""
            controller.recipients = [phoneNumber]
            controller.messageComposeDelegate = self
            self.present(controller, animated: true, completion: nil)
        }
    }

    func messageComposeViewController(_ controller: MFMessageComposeViewController, didFinishWith result: MessageComposeResult) {
        //... handle sms screen actions
        self.dismiss(animated: true, completion: nil)
    }

    override func viewWillDisappear(_ animated: Bool) {
        self.navigationController?.isNavigationBarHidden = false
    }

如果您不想依赖UIViewController，请遵循 Swift 3.0 解决方案：

import UIKit
import MessageUI

class ECMMessageComposerBuilder: NSObject {

    private dynamic var customWindow: UIWindow?
    private var body: String?
    private var phoneNumber: String?
    fileprivate var messageController: MFMessageComposeViewController?

    var canCompose: Bool {
        return MFMessageComposeViewController.canSendText()
    }

    func body(_ body: String?) -> ECMMessageComposerBuilder {
        self.body = body
        return self
    }

    func phoneNumber(_ phone: String?) -> ECMMessageComposerBuilder {
        self.phoneNumber = phone
        return self
    }

    func build() -> UIViewController? {
        guard canCompose else { return nil }

        messageController = MFMessageComposeViewController()
        messageController?.body = body
        if let phone = phoneNumber {
            messageController?.recipients = [phone]
        }
        messageController?.messageComposeDelegate = self

        return messageController
    }

    func show() {
        customWindow = UIWindow(frame: UIScreen.main.bounds)
        customWindow?.rootViewController = MNViewController()

        // Move it to the top
        let topWindow = UIApplication.shared.windows.last
        customWindow?.windowLevel = (topWindow?.windowLevel ?? 0) + 1

        // and present it
        customWindow?.makeKeyAndVisible()

        if let messageController = build() {
            customWindow?.rootViewController?.present(messageController, animated: true, completion: nil)
        }
    }

    func hide(animated: Bool = true) {
        messageController?.dismiss(animated: animated, completion: nil)
        messageController = nil
        customWindow?.isHidden = true
        customWindow = nil
    }
}

extension ECMMessageComposerBuilder: MFMessageComposeViewControllerDelegate {

    func messageComposeViewController(_ controller: MFMessageComposeViewController, didFinishWith result: MessageComposeResult) {
        controller.dismiss(animated: true, completion: nil)
        hide()
    }
}

你以这种方式打电话给作曲家：

let phoneNumber = "987654321"
let composer = MNMessageComposerBuilder()
composer.phoneNumber(phoneNumber).show()

或使用懒惰变种

let phoneNumber = "987654321"
private lazy var messageComposer: MNMessageComposerBuilder = {
    let composer = MNMessageComposerBuilder()
    return composer
}()
messageComposer.phoneNumber(phoneNumber).show()

        let messageVC = MFMessageComposeViewController()

        messageVC.body = "Enter a message";
        messageVC.recipients = ["Enter tel-nr"]
        messageVC.messageComposeDelegate = self;

        self.present(messageVC, animated: false, completion: nil)

        default:
            break;
        }

@IBAction func sendMessageBtnClicked(sender: AnyObject) {
    var messageVC = MFMessageComposeViewController()

    messageVC.body = "Enter a message";
    messageVC.recipients = ["Enter tel-nr"]
    messageVC.messageComposeDelegate = self;

    self.presentViewController(messageVC, animated: false, completion: nil)
}

func messageComposeViewController(controller: MFMessageComposeViewController!, didFinishWithResult result: MessageComposeResult) {
    switch (result.value) {
    case MessageComposeResultCancelled.value:
      println("Message was cancelled")
      self.dismissViewControllerAnimated(true, completion: nil)

要在 Swift 5 中发送iMessage，我使用以下代码

只需 MessageUI 包并实现 MFMessageComposeViewControllerDelegate

import UIKit
import MessageUI

class ViewController: UIViewController, MFMessageComposeViewControllerDelegate {

    override func viewDidLoad() {
        super.viewDidLoad()
    }

    @IBAction func sendNewIMessage(_ sender: Any) {
        let messageVC = MFMessageComposeViewController()
        messageVC.body = "Enter a message details here";
        messageVC.recipients = ["recipients_number_here"]
        messageVC.messageComposeDelegate = self
        self.present(messageVC, animated: true, completion: nil)
    }

    func messageComposeViewController(_ controller: MFMessageComposeViewController, didFinishWith result: MessageComposeResult) {
        switch (result) {
        case .cancelled:
            print("Message was cancelled")
            dismiss(animated: true, completion: nil)
        case .failed:
            print("Message failed")
            dismiss(animated: true, completion: nil)
        case .sent:
            print("Message was sent")
            dismiss(animated: true, completion: nil)
        default:
            break
        }
    }
}

一个简单的解决方案可能是打开html链接：

let mPhoneNumber = "1111111111";
let mMessage = "hello%20phone";
if let url = URL(string: "sms://" + mPhoneNumber + "&body="+mMessage) {
    UIApplication.shared.open(url)
}

确保将空格替换为“％20”
