swift - How to get my location data and put them in variables for iMessage?

Question

Yesterday I asked a question here in stack Overflow about how to embed my current location in message body

I had got an answer and I corrected my code

My code works just fine in console, but i couldn't figure out how to get the data from displayLocationInfo function and store them in variables; then put variables in message body.

I'm sorta new in iPhone development

Any help ?

class Location: NSObject,CLLocationManagerDelegate {


    var locationManager = CLLocationManager()
    var currentLocation : CLPlacemark?
    var detectLocation : CLLocationManager?
    var locManager = CLLocationManager()


     func viewDidLoad()
    {
        viewDidLoad()

        self.locationManager.delegate = self
        self.locationManager.desiredAccuracy = kCLLocationAccuracyBest
        self.locationManager.requestWhenInUseAuthorization()
        self.locationManager.startUpdatingLocation()

    }


    func updateLocation()
    {
          locationManager.startUpdatingLocation()
    }



    func locationManager(manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
        locationManager.stopUpdatingLocation()


        CLGeocoder().reverseGeocodeLocation(manager.location!, completionHandler: {(placemarks, error)->Void in

            if (error != nil)
            {
                print("Error: " + error!.localizedDescription)
                return
            }

            if placemarks!.count > 0
            {
                let pm = placemarks![0]
                self.displayLocationInfo(pm)
            }
            else
            {
                print("Error with the data.")
            }
        })
    }

    func displayLocationInfo(placemark: CLPlacemark)
    {

        self.locationManager.stopUpdatingLocation()
        print(placemark.locality)
        print(placemark.postalCode)
        print(placemark.administrativeArea)
        print(placemark.country)
    }

    func locationManager(manager: CLLocationManager, didFailWithError error: NSError)
    {
        print("Error: " + error.localizedDescription)
    }

}

import MessageUI

make your class the correct delegate (this one is for iMessage):

MFMessageComposeViewControllerDelegate

make some global variables to store the fields you want to store (set them when you are printing to the console in your current code):

class Location: NSObject,CLLocationManagerDelegate, MFMessageComposeViewControllerDelegate {


var locationManager = CLLocationManager()
var currentLocation : CLPlacemark?
var detectLocation : CLLocationManager?
var locManager = CLLocationManager()

//put your variables for your message below:
//you should use optionals (?) here but to keep it simple I'm assigning ""
var locality = ""
var postalCode = ""

//set your variables when you are currently printing them in the console:
func displayLocationInfo(placemark: CLPlacemark)
{

    self.locationManager.stopUpdatingLocation()
    print(placemark.locality)
    print(placemark.postalCode)
    print(placemark.administrativeArea)
    print(placemark.country)

    //here I set postalcode to be used in the message later
    postalCode = placemark.postalCode

}
//call this function when the user hits a send button
func messageAction() {        
    if MFMessageComposeViewController.canSendText() {
        let messageVC = MFMessageComposeViewController()
        messageVC.messageComposeDelegate = self    
        messageVC.body = "\(postalCode) is my postalCode"
        self.presentViewController(messageVC, animated: true, completion: nil)
    }
    else {
        print("User hasn't setup Messages.app")
    }
}

//if you have any code you want to run when the message is done sending put it in
func messageComposeViewController(controller: MFMessageComposeViewController, didFinishWithResult result: MessageComposeResult) {

self.dismissViewControllerAnimated(true, completion: nil)

    switch (result.rawValue) {
    case MessageComposeResultSent.rawValue:
        print("Message sent success")
    default:
        return
    }


}

Another option would be to make the messageAction() method have perameters that you include in your message. Like messageAction(postalCode: String?, locality: String?, municipality: String?) etc. It really depends on if you want to use these values in other methods globally or not.

IN RESPONSE TO QUESTIONS FROM POSTER:

Set a global variable (look in the large code sample above for this line). It makes postalCode a global variable.

var postalCode = ""

In displayLocationInfo() set this variable to have the location's value:

postalCode = placemark.postalCode

In messageAction() set the body of the message to use that variable:

let messageVC = MFMessageComposeViewController()
messageVC.body = "\(postalCode) is my postalCode"

This will make a message that says "12345 is my postalCode" in the text message window.
