I am retrieving the phone number from my Firebase database, no matter how I enter it into the database it returns an error on my device:
"Message sent to invalid destination. Please check your number and try again. Msg 2127"
The message comes in as an automatic reply immediately after the text is sent out. I have tried entering it into firebase as 111-111-1111 and 1111111111 (not actually using a number 1 but a real phone number).
The calling function works fine however the same number being texted is not working.
var contact: Int!
#IBAction func textButton(_ sender: Any) {
if canSendText() {
if let contactopt = contact{
var messageVC = MFMessageComposeViewController()
messageVC.recipients = ["tel:\(contactopt)"]
messageVC.messageComposeDelegate = self;
self.present(messageVC, animated: false, completion: nil)}}
else {
let errorAlert = UIAlertView(title: "Cannot Send Text Message", message: "Your device is not able to send text messages.", delegate: self, cancelButtonTitle: "OK")
errorAlert.show()
}
}
func canSendText() -> Bool {
return MFMessageComposeViewController.canSendText()
}
func messageComposeViewController(_ controller: MFMessageComposeViewController, didFinishWith result: MessageComposeResult) {
controller.dismiss(animated: true, completion: nil)
}
#IBAction func callButton(_ sender: UIButton) {
if let contactopt = contact{
if let url = NSURL(string: "tel://\(contactopt)") {
// UIApplication.shared.openURL(url as URL)
UIApplication.shared.open(url as URL, options: [:], completionHandler: nil)
}
}
}
I had to change
messageVC.recipients = ["tel:(contactopt)"]
messageVC.recipients = [String(contactopt)]

I am facing two major problem first one is :
1. I am trying to detect incoming call, outgoing call , dialing call for this i am using this code :
import UIKit
import CoreTelephony
import CallKit
class ViewController: UIViewController,CXCallObserverDelegate {
let callObserver = CXCallObserver()
var seconds = 0
var timer = Timer()
override func viewDidLoad() {
super.viewDidLoad()
callObserver.setDelegate(self, queue: nil)
}
override func viewWillAppear(_ animated: Bool) {
print("viewWillAppear \(seconds)")
}
fileprivate func runTimer(){
timer = Timer.scheduledTimer(timeInterval: 1, target: self, selector: #selector(self.updateTimer), userInfo: nil, repeats: true)
}
func updateTimer() {
seconds += 1
print("Seconds \(seconds)")
}
#IBAction func callButton(_ sender: UIButton) {
if let url = URL(string: "tel://\(12345879)"){
UIApplication.shared.open(url, options: [:], completionHandler: nil)
}
}
func callObserver(_ callObserver: CXCallObserver, callChanged call: CXCall) {
if call.hasEnded == true {
print("Disconnected")
seconds = 0
self.timer.invalidate()
}
if call.isOutgoing == true && call.hasConnected == false {
print("Dialing call")
self.runTimer()
}
if call.isOutgoing == false && call.hasConnected == false && call.hasEnded == false {
print("Incoming")
}
if call.hasConnected == true && call.hasEnded == false {
print("Connected")
}
}
}
It working fine when i am dialing a number it shows "Dialling" but when i cut the call then it shows "Disconnected" then again "Dialing" State.
Another problem is when i am fetching all contacts information from the device it works fine when i am not fetching imageData but when i am fetching contacts image it works fine for the very first time . Then if i run it again app become slow . then next it crash shows found nil while unwrapping a value.
i wrote my contact data fetching function in AppDelegate . it is calling when the app start . this is the code :
func fetchContactList(){
let loginInformation = LoginInformation()
var contactModelData: [ContactsModel] = []
var profileImage : UIImage?
let store = CNContactStore()
store.requestAccess(for: .contacts, completionHandler: {
granted, error in
guard granted else {
let alert = UIAlertController(title: "Can't access contact", message: "Please go to Settings -> MyApp to enable contact permission", preferredStyle: .alert)
alert.addAction(UIAlertAction(title: "OK", style: .default, handler: nil))
self.window?.rootViewController?.present(alert, animated: true, completion: nil)
return
}
let keysToFetch = [CNContactFormatter.descriptorForRequiredKeys(for: .fullName),CNContactPhoneNumbersKey, CNContactEmailAddressesKey, CNContactPostalAddressesKey, CNContactImageDataKey, CNContactImageDataAvailableKey,CNContactThumbnailImageDataKey,CNContactThumbnailImageDataKey] as [Any]
let request = CNContactFetchRequest(keysToFetch: keysToFetch as! [CNKeyDescriptor])
var cnContacts = [CNContact]()
do {
try store.enumerateContacts(with: request){
(contact, cursor) -> Void in
cnContacts.append(contact)
}
} catch let error {
NSLog("Fetch contact error: \(error)")
}
for contact in cnContacts {
let fullName = CNContactFormatter.string(from: contact, style: .fullName) ?? "No Name"
var phoneNumberUnclean : String?
var labelofContact : String?
var phoneNumberClean: String?
for phoneNumber in contact.phoneNumbers {
if let number = phoneNumber.value as? CNPhoneNumber,
let label = phoneNumber.label {
let localizedLabel = CNLabeledValue<CNPhoneNumber>.localizedString(forLabel: label)
print("fullname \(fullName), localized \(localizedLabel), number \(number.stringValue)")
phoneNumberUnclean = number.stringValue
labelofContact = localizedLabel
}
}
if let imageData = contact.imageData {
profileImage = UIImage(data: imageData)
print("image \(String(describing: UIImage(data: imageData)))")
} else {
profileImage = UIImage(named: "user")
}
self.contactModelData.append(ContactsModel(contactName: fullName, contactNumber:phoneNumberUnclean!, contactLabel: labelofContact!, contactImage: profileImage!, contactNumberClean: phoneNumberUnclean!))
}
self.loginInformation.saveContactData(allContactData: self.contactModelData)
})
}
I have solved this two problems using this :
for number one when i disconnect a call then if unfortunately it goes to "Dialling" option again i checked the "seconds" variable's value if it greater than 0 in "Dialing" then invalidate the thread.
for number two problem :
I used Dispatch.async.main background thread and take the thumbnail image
Set up Apple Pay in my app and it seems to work fine when running on device. Using Stripe as the payment processor but it is not sending the token to Stripe, but seems to be charging the credit card listed in my iPhone's digital wallet.
The problem I am having is that once I press the "Pay with Touch ID", I get a check mark in my Apple Pay sheet but the following page appears in Xcode:
Code for Apple Pay & Stripe
var paymentSucceeded: Bool = false
func paymentAuthorizationViewController(_ controller: PKPaymentAuthorizationViewController,
didAuthorizePayment payment: PKPayment, completion: #escaping (PKPaymentAuthorizationStatus) -> Void) {
STPAPIClient.shared().createToken(with: payment) { (token, error) in
print("I am here")
if error != nil {
completion(.failure)
print("failed")
} else {
self.paymentSucceeded = true
completion(.success)
print("woohoo")
}
self.createBackendCharge(with: token!, completion: completion)
print("created Backend Charge")
self.postStripeToken(token: token!)
print("posted stripe token")
}
} // paymentAuthorizationViewController( didAuthorizePayment )
func createBackendCharge(with token: STPToken, completion: #escaping (_: PKPaymentAuthorizationStatus) -> Void) {
//We are printing Stripe token here, you can charge the Credit Card using this token from your backend.
print("Stripe Token is \(token)")
completion(.success)
} // createBackendCharge func
func paymentAuthorizationViewControllerDidFinish(_ controller: PKPaymentAuthorizationViewController) {
controller.dismiss(animated: true, completion: {
if (self.paymentSucceeded) {
// show a receipt page
}
})
} // paymentAuthorizationViewControllerDidFinish()
#IBAction func applePayPressed(_ sender: UIButton) {
// we have already accepted the request from viewDriverBids
// all that remains is to complete payment
print("enable apple pay")
// send user to Apple Pay to make payment
let paymentNetworks = [PKPaymentNetwork.visa, .masterCard, .interac, .discover, .amex]
if PKPaymentAuthorizationViewController.canMakePayments(usingNetworks: paymentNetworks) {
paymentRequest = PKPaymentRequest()
paymentRequest.currencyCode = "CAD"
paymentRequest.countryCode = "CA"
paymentRequest.merchantIdentifier = "merchant.com.xxx"
paymentRequest.supportedNetworks = paymentNetworks
paymentRequest.merchantCapabilities = .capability3DS
paymentRequest.requiredShippingAddressFields = [.all]
paymentRequest.paymentSummaryItems = self.rydes()
let applePayVC = PKPaymentAuthorizationViewController(paymentRequest: paymentRequest)
applePayVC.delegate = self
self.present(applePayVC, animated: true, completion: {
rRydeHandler.Instance.completeApplePay()
self.paymentComplete = true
self.updateDriverInfoView()
})
} else {
print("Tell the user they need to set up Apple Pay!")
}
} // applePayPressed func ACTION
backend server func
func postStripeToken(token: STPToken) {
let URL = "http://localhost/donate/payment.php"
let params = ["stripeToken": token.tokenId,
"amount": Int(self.driverInfoView.rydeFare.text!)!,
"currency": "cad",
"description": self.riderName] as [String : Any]
let manager = AFHTTPSessionManager()
manager.post(URL, parameters: params, success: { (operation, responseObject) -> Void in
if let response = responseObject as? [String: String] {
let alertController = UIAlertController(title: response["status"], message: response["message"], preferredStyle: .alert)
let defaultAction = UIAlertAction(title: "OK", style: .default, handler: nil)
alertController.addAction(defaultAction)
self.present(alertController, animated: true, completion: nil)
}
}) { (operation, error) -> Void in
self.handleError(error as NSError)
print(error)
}
}
How can I resolve this issue?
Enable exception breakpoints then Xcode should crash on the line that is causing the issue.
It is almost certainly caused by one of the ! in your code.
Force unwrapping values is very dangerous. It's always better and safer to unwrap it in a guard let or if let.
I'm using Xcode 8 to build an application for iPhone.My simple app has an button. When user tap on this button, messageComposeViewController is called and with phone number and message content filled.The message went through successfully when I clicked on Send button.The problem is MessageComposeViewController is showing only once.After the message sent, when I tapped on the button to call it, a black screen showed up instead of the message composer.My code is attached below. I appreciate any help.
import UIKit
import MessageUI
class ViewController: UIViewController, MFMessageComposeViewControllerDelegate {
let msg = MFMessageComposeViewController()
#IBOutlet weak var coordinate_label: UILabel!
override func viewDidLoad() {
super.viewDidLoad()
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
}
#IBAction func sendMessage(_ sender: AnyObject) {
self.msg.body = "Message Content"
self.msg.recipients = ["xxx-xxx-xxxx"]
self.msg.messageComposeDelegate = self
self.present(msg, animated: false, completion: nil)
}
func messageComposeViewController(_ controller: MFMessageComposeViewController, didFinishWith result: MessageComposeResult) {
switch result.rawValue {
case MessageComposeResult.cancelled.rawValue:
dismiss(animated: true, completion: nil)
case MessageComposeResult.failed.rawValue:
dismiss(animated: true, completion: nil)
case MessageComposeResult.sent.rawValue:
dismiss(animated: true, completion: nil)
default:
break;
}
}
}
Try this code
import Foundation
import MessageUI
let textMessageRecipients = ["1-800-867-5309"] // for pre-populating the recipients list (optional, depending on your needs)
class MessageComposer: NSObject, MFMessageComposeViewControllerDelegate {
// A wrapper function to indicate whether or not a text message can be sent from the user's device
func canSendText() -> Bool {
return MFMessageComposeViewController.canSendText()
}
// Configures and returns a MFMessageComposeViewController instance
func configuredMessageComposeViewController() -> MFMessageComposeViewController {
let messageComposeVC = MFMessageComposeViewController()
messageComposeVC.messageComposeDelegate = self // Make sure to set this property to self, so that the controller can be dismissed!
messageComposeVC.recipients = textMessageRecipients
messageComposeVC.body = "Hey friend - Just sending a text message in-app using Swift!"
return messageComposeVC
}
// MFMessageComposeViewControllerDelegate callback - dismisses the view controller when the user is finished with it
func messageComposeViewController(controller: MFMessageComposeViewController!, didFinishWithResult result: MessageComposeResult) {
controller.dismissViewControllerAnimated(true, completion: nil)
}
}
Note, latest syntax 2017 ..
func messageComposeViewController(_ controller: MFMessageComposeViewController, didFinishWith result: MessageComposeResult) {
controller.dismiss(animated: true, completion: nil)
}
In Your viewController ..
import UIKit
class ViewController: UIViewController {
// Create a MessageComposer
let messageComposer = MessageComposer()
#IBAction func sendTextMessageButtonTapped(sender: UIButton) {
// Make sure the device can send text messages
if (messageComposer.canSendText()) {
// Obtain a configured MFMessageComposeViewController
let messageComposeVC = messageComposer.configuredMessageComposeViewController()
// Present the configured MFMessageComposeViewController instance
// Note that the dismissal of the VC will be handled by the messageComposer instance,
// since it implements the appropriate delegate call-back
presentViewController(messageComposeVC, animated: true, completion: nil)
} else {
// Let the user know if his/her device isn't able to send text messages
let errorAlert = UIAlertView(title: "Cannot Send Text Message", message: "Your device is not able to send text messages.", delegate: self, cancelButtonTitle: "OK")
errorAlert.show()
}
}
}
As per title, I'm having some trouble dealing with socket.io. It connects really well and accordingly in the first view controller but weird things happen when it comes to second controller.
Here's the code:
First Controller: I have declared some global variable for connection purposes between both view controller.
import UIKit
import SocketIOClientSwift
import SwiftyJSON
import CoreData
//declare some global variable
var patientCoreData = [NSManagedObject]()
var numberOfUsersExisting:Int = 0 //assign to 0 by default
var appUserData: Patient? //for specific user
var pSample: Array<Patient> = [] //for all user
//initiate socket globally
let socket = SocketIOClient(socketURL: "localhost:3000", options: [
"reconnects": true
])
func reportStatus(){
socket.on("connect") {data, ack in
print("Report status: View Controller connected")
socket.emit("click", "Client app connected")
}
}
func readDataFromSocket(completion: (data:AnyObject)-> ()){
socket.on("reply") {data, ack in
print("database replied")
completion(data: data)
}//socket
}//readDataFromSOCKET
func importData(){
reportStatus()
socket.connect()
readDataFromSocket(){ data in
let json = JSON(data)
let nou = json[0].count
if nou > 0 {
print("Test(1st VC): grabbing data from database")
for var i=0; i<nou; ++i{
numberOfUsersExisting = nou
pSample += [Patient(id: json[0][i]["ID"].intValue, name: json[0][i]["Name"].stringValue, gender: json[0][i]["Gender"].stringValue, mileage: json[0][i]["Mileage"].doubleValue)]
pSample.sortInPlace({$0.globalPatientMileAge < $1.globalPatientMileAge})
}
print("Successfully grabbed data")
}else{
print("No user in the database")
numberOfUsersExisting = 0
}
}//readDataFromSocket
}
class ViewController: UIViewController, UICollectionViewDataSource, UICollectionViewDelegate, UICollectionViewDelegateFlowLayout{
let prefs:NSUserDefaults = NSUserDefaults.standardUserDefaults()
}
override func viewDidLoad() {
super.viewDidLoad()
}
override func viewDidAppear(animated: Bool) {
super.viewDidAppear(animated)
print("First view appeared")
let prefs = NSUserDefaults.standardUserDefaults()
//if an user has logged in
let isLoggedIn = prefs.integerForKey("ISLOGGEDIN") as Int
if (isLoggedIn != 1){
print("No user currently, so heading to login screen")
socket.disconnect()
self.performSegueWithIdentifier("gotoLogin", sender: self)
}else{
print("ViewDidAppear: An user has been logged in")
let permissionToLoadData = prefs.integerForKey("ISLOGGEDIN")
if (permissionToLoadData != 1) {
print("Please grant permission to get data")
}else{
print("First view: connecting to database")
importData()
}//permission to load data
}
}//end of viewDidAppear
}
Second Controller:
import UIKit
import SocketIOClientSwift
import SwiftyJSON
import CoreData
var nou:Int?
class LoginViewController: UIViewController {
let prefs:NSUserDefaults = NSUserDefaults.standardUserDefaults()
let registeredUserID = NSUserDefaults.standardUserDefaults().stringForKey("registerPatientID")
let appDel:AppDelegate = UIApplication.sharedApplication().delegate as! AppDelegate
func displayAlertMessage(userMessage:String){
let alert = UIAlertController(title: "Alert", message: userMessage, preferredStyle: UIAlertControllerStyle.Alert)
let okAction = UIAlertAction(title: "OK", style: UIAlertActionStyle.Default, handler: nil)
alert.addAction(okAction)
self.presentViewController(alert, animated: true, completion: nil)
}
func successMessage(userMessage:String){
let alert = UIAlertController(title: "Welcome Back", message: userMessage, preferredStyle: UIAlertControllerStyle.Alert)
let okAction = UIAlertAction(title: "OK", style: UIAlertActionStyle.Default, handler: nil)
alert.addAction(okAction)
self.presentViewController(alert, animated: true, completion: nil)
}
#IBOutlet weak var loginPatientID: UITextField!
#IBAction func LoginButton(sender: AnyObject) {
let logInUserID = loginPatientID.text
if (logInUserID!.isEmpty){
displayAlertMessage("Please enter your Patient ID!")
return
}else{
print("Test: requesting login permission from database")
socket.emit("loginRequest", logInUserID!)
print("Test: requested")
socket.on("loginReply") {data, ack in
let jsonLogin = JSON(data)
if jsonLogin[0].intValue == 1{
print("Test: ID Matched, putting up ViewController")
self.prefs.setObject(logInUserID, forKey: "AppUserID")
self.prefs.setInteger(1, forKey: "ISLOGGEDIN")
self.prefs.synchronize()
let permissionToLoadData = self.prefs.integerForKey("ISLOGGEDIN")
if (permissionToLoadData != 1) {
print("Please grant permission to get data")
}else{
print("First view: connecting to database")
importData()
print("Did you import?")
}//permission to load data
self.loginPatientID.resignFirstResponder()
self.dismissViewControllerAnimated(true, completion: nil)
}else if jsonLogin[0].intValue == 0{
self.displayAlertMessage("Sorry, you are not assigned to this program")
}else if jsonLogin[0].intValue == 3{
print("Test: Query problem")
}else{
print("Test: not getting anything from ID database")
}
}//socket.on
}//else
}//login button
override func viewDidLoad() {
super.viewDidLoad()
print("Login View Controller loaded")
}
override func viewDidAppear(animated: Bool) {
socket.connect()
print("LoginVC: establishing connection")
}
override func touchesBegan(touches: Set<UITouch>, withEvent event: UIEvent?) {
self.view.endEditing(true)
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
}
}
You may have noticed that in First view controller, when the viewDidAppear() is launched, the app will checks if user is login or not. If somebody has already logged in, it's fine. If there is nobody logging in, it will perform a segue(modally segue) to Second view controller.
A login form will be presented in second view controller and once user hits the login button, you might wanna look at the code.
Let's assume that everything goes right until it comes to importData(), the function isn't launched at all but the app just goes on, why?
Here's a screenshot of the console, pay attention to "Did you import?", if the function is launched, the app should return some additional message from 1st view controller.
After struggling for a few days, I think I may have found the correct answer.
Eventually I defined 2 different socket handlers connection as such:
let loginSocket = SocketIOClient(socketURL: "localhost:3000")
let socket = SocketIOClient(socketURL: "localhost:3000", options: [
"reconnects": true
])
for both view controller.
If there is a conclusion I can draw from this conundrum is that we can't use single socket handler for socket methods from different view controller.
First of all, I'm really surprised that this is not a duplicate, because there are TONS of stackoverflow questions that solve this in Objective-C, but I have yet to see a good answer that used Swift.
What I'm looking for is a code snippet in Swift that sends an arbitrary string as a the body of a text message to given phone number. Essentially, I'd like something like this from Apple's official documentation, but in Swift instead of Objective-C.
I imagine this isn't too difficult, as it can be done in just a couple of lines of code in Android.
EDIT: What I'm looking for is 5-20 lines of Swift code, I do not agree that this is too broad. In Java (for Android), the solution looks like this:
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);
}
}
Now this is the android solution, and it's only 11 lines. Java tends to be much more verbose than Swift, so I doubt what I'm asking is "too broad", it is more likely that I don't know how to use the Objective-C MessageComposer object, because the documentation that I linked to above is unclear with regard to usage in Swift.
Not sure if you really got the answer. I was in a similar hunt and came across this solution and got it to work.
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 Solution:
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
}
For sending iMessage in Swift 5 I use following code
Just MessageUI package and implement 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")
case .failed:
print("Message failed")
case .sent:
print("Message was sent")
default:
return
}
dismiss(animated: true, completion: nil)
}
}
Simpler solution may be opening html link:
let mPhoneNumber = "1111111111";
let mMessage = "hello%20phone";
if let url = URL(string: "sms://" + mPhoneNumber + "&body="+mMessage) {
UIApplication.shared.open(url)
}
Make sure you replaced spaces with "%20"
Swift 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;
}
}
UI will look like:
If you do not want to depend on an UIViewController, follows a Swift 3.0 solution:
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()
}
}
You call the composer this way:
let phoneNumber = "987654321"
let composer = MNMessageComposerBuilder()
composer.phoneNumber(phoneNumber).show()
or using a lazy var
let phoneNumber = "987654321"
private lazy var messageComposer: MNMessageComposerBuilder = {
let composer = MNMessageComposerBuilder()
return composer
}()
messageComposer.phoneNumber(phoneNumber).show()
#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)
case MessageComposeResultFailed.value:
println("Message failed")
self.dismissViewControllerAnimated(true, completion: nil)
case MessageComposeResultSent.value:
println("Message was sent")
self.dismissViewControllerAnimated(true, completion: nil)
default:
break;
}
}
