ios - signo - porque no puedo enviar fotos por mensaje desde mi iphone

Envío de SMS en iOS con Swift

Question

Antes que nada, estoy realmente sorprendido de que esto no sea un duplicado, porque hay TONELADAS de preguntas de stackoverflow que resuelven esto en Objective-C, pero aún no he visto una buena respuesta que use Swift.

Lo que estoy buscando es un fragmento de código en Swift que envía una cadena arbitraria como el cuerpo de un mensaje de texto a un número de teléfono determinado. Esencialmente, me gustaría algo como this de la documentación oficial de Apple, pero en Swift en lugar de Objective-C.

Me imagino que esto no es demasiado difícil, ya que se puede hacer en un par de líneas de código en Android.

EDITAR: Lo que estoy buscando son 5-20 líneas de código Swift, no estoy de acuerdo con que esto sea demasiado amplio. En Java (para Android), la solución se ve así:

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);
     }
}

Ahora esta es la solución de Android, y solo son 11 líneas. Java tiende a ser mucho más detallado que Swift, entonces dudo que lo que estoy pidiendo sea "demasiado amplio", es más probable que no sepa cómo usar el objeto MessageComposer de Objective-C, porque la documentación que he vinculado para arriba no está claro con respecto al uso en Swift.

Answer 1

No estoy seguro de si realmente recibiste la respuesta. Estaba en una búsqueda similar y encontré esta solución y la hice funcionar.

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
    }
}

Si no quiere depender de un UIViewController, sigue una solución Swift 3.0 :

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()
    }
}

Llamas al compositor de esta manera:

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

o usando una varita floja

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

Solución Swift 3.0:

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
    }

@IBAction func sendSmsClick(_ sender: AnyObject) {
        let messageVC = MFMessageComposeViewController()

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

            print("Message was cancelled")
            self.dismiss(animated: true, completion: nil)
        case MessageComposeResult.failed.rawValue:

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