使用Swift在iOS中发送短信

Question

首先,我真的很惊讶这不是重复,因为有很多堆栈溢出问题可以在Objective-C中解决这个问题,但是我还没有看到使用Swift的好答案.

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给给定的电话号码.从本质上讲,我希望像这样从苹果的官方文档,但是在斯威夫特,而不是Objective-C的.

我想这不是太难,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,我不同意这是太宽泛了.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的往往要比雨燕更详细的,所以我怀疑什么,我问的是"过于宽泛",但更有可能的是,我不知道如何使用Objective-C的MessageComposer对象,因为我链接的文档关于在Swift中的使用情况,上面的内容尚不清楚.

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
    }

斯威夫特 3、4、5

@IBAction func sendSmsClick(_ sender: AnyObject) {
        guard MFMessageComposeViewController.canSendText() else {
            return
        }

        let messageVC = MFMessageComposeViewController()

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

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

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

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()
    }
}

你这样称呼作曲家：

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

或使用惰性变量

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

Answer 5

为了在Swift 5中发送iMessage，我使用以下代码

只是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
        }
    }
}

Answer 6

更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)
}

确保用“%20”替换空格
