I want to redraw my direction path and move my marker to the current location. I am currently doing this inside didUpdateLocations function but it gets glitchy because it draws multiple markers and path at the same time.
Here is my code:
let location = locations.last
let destination = CLLocation(latitude: order!.user_coord![0], longitude: order!.user_coord![1])
let origin = CLLocation(latitude: (location?.coordinate.latitude)!, longitude: (location?.coordinate.longitude)!)
self.drawPath(startLocation: origin, endLocation: destination)
self.createMarker(titleMarker: order!.store_name!, iconMarker: UIImage(named: "icons8-user_filled")!, latitude: order!.user_coord![0], longitude: order!.user_coord![1])
self.createMarker(titleMarker: "User", iconMarker: UIImage(named: "icons8-mountain_biking")!, latitude: (location?.coordinate.latitude)!, longitude: (location?.coordinate.longitude)!)
let camera = GMSCameraPosition.camera(withLatitude: (location?.coordinate.latitude)!, longitude: (location?.coordinate.longitude)!, zoom: 17.0)
self.map.animate(to: camera)
locationManager.stopUpdatingLocation()
Declare a variable
var drawFinished:Bool!
in viewDidLoad
drawFinished = false
in didUpdate
if(!drawFinished)
{
drawFinished = true
let location = locations.last
let destination = CLLocation(latitude: order!.user_coord![0], longitude: order!.user_coord![1])
let origin = CLLocation(latitude: (location?.coordinate.latitude)!, longitude: (location?.coordinate.longitude)!)
self.drawPath(startLocation: origin, endLocation: destination)
self.createMarker(titleMarker: order!.store_name!, iconMarker: UIImage(named: "icons8-user_filled")!, latitude: order!.user_coord![0], longitude: order!.user_coord![1])
self.createMarker(titleMarker: "User", iconMarker: UIImage(named: "icons8-mountain_biking")!, latitude: (location?.coordinate.latitude)!, longitude: (location?.coordinate.longitude)!)
let camera = GMSCameraPosition.camera(withLatitude: (location?.coordinate.latitude)!, longitude: (location?.coordinate.longitude)!, zoom: 17.0)
self.map.animate(to: camera)
locationManager.stopUpdatingLocation()
}
when you want to update set
drawFinished = false
and clear paths and annotations like this
func clearMapOverlays()
{
for dl in self.myMapView.overlays
{
if(dl is GMSPolyline )
{
self.myMapView.remove(dl)
}
}
self.myMapView.setNeedsDisplay()
for name in self.myMapView.annotations
{
self.myMapView.removeAnnotation(anno)
}
}
I have to plot multiple pins in a Google Map view, and then zoom to the user's current location. Pins are plotted successfully but not zoomed to current location. Any help would be appreciated
override func viewDidAppear(_ animated: Bool) {
if (self.googleMapsView == nil) {
self.googleMapsView = GMSMapView(frame: self.mapViewContainer.frame)
self.view.addSubview(self.googleMapsView)
print(AppDelegate.getAppDelegate().mapArray)
googleMapsView.clear()
for i in 0...AppDelegate.getAppDelegate().mapArray.count - 1 {
let lon = Double ((AppDelegate.getAppDelegate().mapArray[i]["lon"] as? String)!)
let lat = Double ((AppDelegate.getAppDelegate().mapArray[i]["lat"] as? String)!)
let tit = AppDelegate.getAppDelegate().mapArray[i]["location"] as? String
locateWithLongitude(lon: lon!,andLatitude: lat! ,andTitle: tit!)
}
let marker = GMSMarker(position: AppDelegate.getAppDelegate().myLocation)
let camera = GMSCameraPosition.camera(withLatitude: AppDelegate.getAppDelegate().myLocation.latitude, longitude: AppDelegate.getAppDelegate().myLocation.longitude, zoom: 11)
self.googleMapsView.camera = camera
marker.title = AppDelegate.getAppDelegate().sublocality
marker.map = self.googleMapsView
self.googleMapsView.animate(to: camera)
}
}
func locateWithLongitude(lon: Double, andLatitude lat: Double, andTitle title: String) {
DispatchQueue.main.async() { () -> Void in
let position = CLLocationCoordinate2DMake(lat, lon)
let marker = GMSMarker(position: position)
let camera = GMSCameraPosition.camera(withLatitude: lat, longitude: lon, zoom: 0)
self.googleMapsView.camera = camera
marker.title = title
marker.map = self.googleMapsView
}
}
Your zoom is set to 0, increase it to 15/16 like bellow.
let camera = GMSCameraPosition.camera(withLatitude: lat, longitude: lon, zoom: 16)
I'm using Google PlacePicker API in my iOS application using Swift 3.0.
I need 13 digits of precision after the decimal. But Google PlacePicker is returning latitude and longitude with 7 digits after the decimal.
Below is my function:
func pickPlace(sender: UIButton) {
let center = CLLocationCoordinate2D(latitude: (locationManager.location?.coordinate.latitude)!, longitude: (locationManager.location?.coordinate.longitude)!)
let northEast = CLLocationCoordinate2D(latitude: center.latitude + 0.001, longitude: center.longitude + 0.001)
let southWest = CLLocationCoordinate2D(latitude: center.latitude - 0.001, longitude: center.longitude - 0.001)
let viewport = GMSCoordinateBounds(coordinate: northEast, coordinate: southWest)
let config = GMSPlacePickerConfig(viewport: viewport)
let placePicker = GMSPlacePicker(config: config)
placePicker.pickPlace(callback: {(place, error) -> Void in
if let error = error {
print("Pick Place error: \(error.localizedDescription)")
return
}
if let place = place {
let coordinates = CLLocationCoordinate2DMake(place.coordinate.latitude, place.coordinate.longitude)
let marker = GMSMarker(position: coordinates)
marker.title = place.name
marker.map = self.googleMapView
self.googleMapView.animate(toLocation: coordinates)
let geoCode = "\(place.coordinate.latitude),\(place.coordinate.longitude)"
self.showGeoSelector(title: "Selected Coordinates", message: "Latitude: " + String(place.coordinate.latitude) + " Longitude: " + String(place.coordinate.longitude), geoCode: geoCode, geoLat: String(place.coordinate.latitude), geoLong: String(place.coordinate.longitude))
}
})
}
Try this code:
let geoCode = "\(String(format: "%.18f", place.coordinate.latitude)),\(String(format: "%.18f", place.coordinate.longitude))"
Hope its helps :)
I have one Annotation on my map showing a business location and one button that says get directions, I'm struggling to get the button to open Apple Maps for me with directions to the Annotations location. Here is the code I have done so far:
import UIKit
import MapKit
class FourthViewController: UIViewController , MKMapViewDelegate {
#IBOutlet weak var map: MKMapView!
override func viewDidLoad() {
super.viewDidLoad()
let latitude: CLLocationDegrees = 54.647115
let longitude: CLLocationDegrees = -6.659070
let lanDelta: CLLocationDegrees = 0.05
let lonDelta: CLLocationDegrees = 0.05
let span = MKCoordinateSpan(latitudeDelta: lanDelta, longitudeDelta: lonDelta)
let coordinates = CLLocationCoordinate2D(latitude: latitude, longitude: longitude)
let region = MKCoordinateRegion(center: coordinates, span: span)
map.setRegion(region, animated: true)
let annotation = MKPointAnnotation()
annotation.title = "Pose Beauty Salon"
annotation.subtitle = "100 Moneyhaw Road"
annotation.coordinate = coordinates
map.addAnnotation(annotation)
}
#IBAction func mapType(_ sender: AnyObject) {
switch (sender.selectedSegmentIndex) {
case 0:
map.mapType = .standard
case 1:
map.mapType = .satellite
default: // or case 2
map.mapType = .hybrid
}
}
#IBAction func getDirections(_ sender: AnyObject) {
}
}
I've also seen annotations when clicked on that shows more info such as business names, addresses, phone numbers, and URLs is this hard to add also?
This is the code I used to resolve the issue:
let latitude: CLLocationDegrees = 54.647115
let longitude: CLLocationDegrees = -6.659070
let url = URL(string: "https://www.posebeautysalon.com")
let regionDistance:CLLocationDistance = 10000
let coordinates = CLLocationCoordinate2DMake(latitude, longitude)
let regionSpan = MKCoordinateRegionMakeWithDistance(coordinates, regionDistance, regionDistance)
let options = [
MKLaunchOptionsMapCenterKey: NSValue(mkCoordinate: regionSpan.center),
MKLaunchOptionsMapSpanKey: NSValue(mkCoordinateSpan: regionSpan.span)
]
let placemark = MKPlacemark(coordinate: coordinates, addressDictionary: nil)
let mapItem = MKMapItem(placemark: placemark)
mapItem.name = "Pose Beauty Salon"
mapItem.phoneNumber = "+442886737777"
mapItem.url = url
mapItem.openInMaps(launchOptions: options)
Problem:
I'm trying to make it so that it uses the user's location all the time and constantly checks to see if it is within 5 miles of the CLLocationCoordinate2D points I have set. If so, it sends a alert if the app is open or a notification if the app is closed.
Useful Information:
In my project I have 4 swift files:
Locations.swift holds the CLLocationCoordinate2D points.
Utilities.swift holds a simple alert.
UserLocation.swift retrieves and updates the user's location
GeoLocationViewController.swift monitors the locations
Note:
Some code may not be in the right place or relevant, I was looking at another project trying to extract relevant code from it to use in my project. Please tell me if you do catch a mistake.

First and foremost, change back startMonitoringGeotification(), regionWithGeotification(), and stopMonitoringGeotification() to take in a Geotification like the Ray Wenderlich tutorial. Make sure you have added the file Geotification.swift from his starter code to your project.
Also, make sure your Main.storyboard launches your ViewController. Without this step, none of your code will run.
1) redefine your Locations class more simply in Locations.swift:
import UIKit
import MapKit
class Locations {
static let locations:[String:CLLocationCoordinate2D] = [
"buddyrogers" : CLLocationCoordinate2D(latitude: 33.815995425565184, longitude: -116.44107442645873),
"diamond" : CLLocationCoordinate2D(latitude: 33.802168595307814, longitude: -116.45711048941041),
.
. // add your locations
.
]
}
}
like the #hungry-yeti suggested
2) You can define showSimpleAlertWithTitle() in your GeotificationViewController class. Try calling it in your ViewDidLoad() to test it. You can now delete Utilities.swift.
3) I think you can ignore/remove UserLocation.swift, this seems unnecessary
4) Put this code inside GeotificationViewController's ViewDidLoad:
let radius = CLLocationDistance(8046.72) // 5 miles in meters
for location in Locations.locations {
let g = Geotification(coordinate: location.1, radius: radius, identifier: location.0, note: "test", eventType: EventType.OnEntry)
startMonitoringGeotification(g)
}
5) I hope this helps and simplifies your code. Party on, reply here if you have any issues.
It looks like you're using the Ray Wenderlich tutorial. That's a good one, I found it very useful too.
First off, the unit for CLLocationDistance is meters so the code you have specifies a radius of 5 meters which won't be quite as useful as you may hope; a value of 8046.72 is closer to 5 miles.
Regarding the specific error, Locations is the class that you stuffed all CLLocationCoordinate2D values in, it certainly does not have any member called coordinate. If you're using the tutorial I'm thinking of you will need to load those coords into instances of the Geotification class.
Here is some untested code:
// Load the various coords into an array:
var locations:[(note:String, coords:CLLocationCoordinate2D)] = []
locations +=[(note: "arroyo", CLLocationCoordinate2D( latitude: 33.781327997137595, longitude: -116.46394436519012)]
locations +=[(note: "buddyrogers", CLLocationCoordinate2D( latitude: 33.78051204742721, longitude: -116.46362250010833)]
// ...
let radius = 8000 // ~5 miles rounded to nearest km
// Load the locations into geotifications:
for location in locations {
let geotification = Geotification(coordinate: location.cords, radius: radius, identifier: NSUUID().UUIDString, note: location.note, eventType: EventType.OnEnter)
startMonitoringGeotification(geotification)
}
Now bear in mind that there is a hard limit of 20 monitored regions per app, so if you have more than that you will need to dynamically determine the nearest 20 regions and then monitor those regions.
