Stormy Remix!

Hello!

So I figured out how to grab the user location and implement it into the Stormy App. The problem is that it's not working on launch. The user must refresh the data before it works.

Here is the code. 

import UIKit
import CoreLocation

class ViewController: UIViewController,CLLocationManagerDelegate {

    var seenError : Bool = false
    var locationFixAchieved : Bool = false
    var locationStatus : NSString = "Not Started"
    var locationManager: CLLocationManager!
    var userLocation : String!
    var userLatitude : Double!
    var userLongitude : Double!

    @IBOutlet weak var iconView: UIImageView!
    @IBOutlet weak var currentTimeLabel: UILabel!
    @IBOutlet weak var temperatureLabel: UILabel!
    @IBOutlet weak var humidityLabel: UILabel!
    @IBOutlet weak var precipitationLabel: UILabel!
    @IBOutlet weak var summaryLabel: UILabel!
    @IBOutlet weak var refreshButton: UIButton!
    @IBOutlet weak var refreshActivityIndicator: UIActivityIndicatorView!


    private let apiKey = "your API KEY :)"


    override func viewDidLoad() {
        super.viewDidLoad()

        // Do any additional setup after loading the view, typically from a nib.

        initLocationManager()

        getCurrentWeatherData()

    }


    // This is the Location code

    func initLocationManager() {
        seenError = false
        locationFixAchieved = false
        locationManager = CLLocationManager()
        locationManager.delegate = self
        locationManager.desiredAccuracy = kCLLocationAccuracyBest
        locationManager.requestAlwaysAuthorization()
        locationManager.startUpdatingLocation()    }

    func locationManager(manager: CLLocationManager!, didFailWithError error: NSError!) {
        locationManager.stopUpdatingLocation()
        if ((error) != nil) {
            if (seenError == false) {
                seenError = true
                print(error)
            }
        }
    }

    func locationManager(manager: CLLocationManager!, didUpdateLocations locations: [AnyObject]!) {
        if (locationFixAchieved == false) {
            locationFixAchieved = true
            var locationArray = locations as NSArray
            var locationObj = locationArray.lastObject as CLLocation
            var coord = locationObj.coordinate

            //println(coord.latitude)
            //println(coord.longitude)

            self.userLatitude = coord.latitude
            self.userLongitude = coord.longitude

            println(userLocation)

        }
    }

    func locationManager(manager: CLLocationManager!,
        didChangeAuthorizationStatus status: CLAuthorizationStatus) {
            var shouldIAllow = false

            switch status {
            case CLAuthorizationStatus.Restricted:
                locationStatus = "Restricted Access to location"
            case CLAuthorizationStatus.Denied:
                locationStatus = "User denied access to location"
            case CLAuthorizationStatus.NotDetermined:
                locationStatus = "Status not determined"
            default:
                locationStatus = "Allowed to location Access"

            if (shouldIAllow == true) {
                NSLog("Location to Allowed")
                // Start location services
                locationManager.startUpdatingLocation()
            } else {
                NSLog("Denied access: \(locationStatus)")
            }
    }

Do you mean that you don't get the dialog requesting access to location right when the app starts?

agreatdaytocode

Pasan, I get the dialog, but the user location is not updated until after I hit the refresh button. The first thing that pop's up is the message ""Error unable to load data. Connectivity error!"

This kind of location manager configuration is overkill for a weather app:

locationManager = CLLocationManager()
locationManager.delegate = self
locationManager.desiredAccuracy = kCLLocationAccuracyBest
locationManager.requestAlwaysAuthorization()
locationManager.startUpdatingLocation()

A navigation app or an app providing users with info about landmarks in their vicinity would use kCLLocationAccuracyBest. A weather app can make do with kCLLocationAccuracyThreeKilometers.

Also, monitoring for all location changes instead of significant ones will burn through the device battery fairly quickly (especially with the default value of the distanceFilter property).

Once you only monitor for significant changes, you can have the locationManager(_:didUpdateLocations:) method call the function that updates the weather info, and it won't be triggered every second, but rather when users make a significant location change (when they change cell towers). Users won't need to refresh manually, the location manager delegate function will do it for them once it gets a fix on the current location.

any idea on how to make sure the location gets pasted to the userLocation before the locationManager launches?

Never mind I figured it out : ) I added the getCurrentWeatherData() to the locationManger func and it works like a charm now.

I was using this to test out the daily weather info that I wanted to bring in same for the mynewTemp. It was test code for the high and low for the current day.

If you remove both you should be ok.

I keep getting a denied access: Status not determined warning. I'm testing on an actual device. In settings/general/privacy/location/story I set the location to allow always. However every time I rerun the app it doesn't remember this setting. Any advice?

Also, thanks for clearing up the above problem!

Hello Aaron, I copied and pasted that code into a blank project, added the key to the .plist file (and imported the CoreLocation framework), and I don't get any errors, but nothing comes up in the console when I run it.

Also, what label are you connecting "@IBOutlet weak var myTestLabel: UILabel!" to? Thanks!

For label I get coordinates, how can I get a string of a name of a town they're in?

Hi Joe,

You can bring this in via locality and administrative Area.

func displayLocationInfo(placemark: CLPlacemark?) {
        if let containsPlacemark = placemark {
            //stop updating location to save battery life
            locationManager.stopUpdatingLocation()
            let locality = (containsPlacemark.locality != nil) ? containsPlacemark.locality : ""
            let postalCode = (containsPlacemark.postalCode != nil) ? containsPlacemark.postalCode : ""
            let administrativeArea = (containsPlacemark.administrativeArea != nil) ? containsPlacemark.administrativeArea : ""
            let country = (containsPlacemark.country != nil) ? containsPlacemark.country : ""
            //println(locality)
            //println(postalCode)
            //println(administrativeArea)
            //println(country)

            self.userLocationLabel.text = "\(locality), \(administrativeArea)"
        }
