I want to show live tracking in Map View.I am having latitudes and Longitudes List in separate Array… How to Show this in Map as a point.. Please anybody HelpOut For this Problem.
func locationManager(manager: CLLocationManager!, didUpdateLocations locations: [AnyObject]!)
{
let location = locations.last as! CLLocation
let location1 = locations.first as! CLLocation
// Have to get OldLocation And New Location From API
let oldCoordinates = location.coordinate
let newCoordinates = location1.coordinate
var area = [oldCoordinates, newCoordinates]
let polyline = MKPolyline(coordinates: &area, count: area.count)
mapView.add(polyline)
self.currentCLLocation = CLLocationCoordinate2D(latitude: newCoordinates.latitude, longitude: newCoordinates.longitude)
let region = MKCoordinateRegion(center: self.currentCLLocation, span: MKCoordinateSpan(latitudeDelta: 0.01, longitudeDelta: 0.01))
self.mapView.setRegion(region, animated: true)
print("Location Update Details")
print(location.coordinate.latitude)
print(location.coordinate.longitude)
self.mapView.delegate = self
let annotation = MKPointAnnotation()
annotation.coordinate = location1.coordinate
self.mapView.addAnnotation(annotation)
}
Values In Array:

How to Loop the latitude and Longitude Values in Location and Location1 Variable?
DidUpdate Method is not getting called Every time we update map?
How To show Polyline based on Lat and Long?
How can i sort the array based on distance from current location and show in tableview .when i use sorting am not getting any proper results ,am getting the array with random distance.can any one guide me for solve this issue
To sort locations based on distance from current location in best possible way would be have location points in form of struct
struct LocationPoints {
var latitude: CLLocationDegrees
var longitude: CLLocationDegrees
func distance(to currentLocation: CLLocation) -> CLLocationDistance {
return CLLocation(latitude: self.latitude, longitude: self.longitude).distance(from: currentLocation)
}
}
Let suppose you have an array of LocationPoints having latitude & longitude
var coordinates: [LocationPoints] = []
coordinates.append(LocationPoints(latitude: Double(25), longitude: Double(24)))
coordinates.append( LocationPoints(latitude: Double(23), longitude: Double(22)))
sort function
coordinates = sortLocationsWithCurrentLocation(locations: coordinates, currentLocation: CLLocation(latitude: Double(20), longitude: Double(21)))
func sortLocationsWithCurrentLocation(locations:[LocationPoints],currentLocation:CLLocation) -> [LocationPoints] {
//set here current position as current location
let currentPosition : CLLocation = CLLocation(latitude: 30, longitude: 24)
let sortedLocations = locations.sorted(by: { (point1 : LocationPoints, point2 :LocationPoints) -> Bool in
if point1.distance(to: currentPosition) < point2.distance(to: currentPosition)
{
return true
}
return false
})
return sortedLocations
}
I am trying to show three things on map :
GPS (the current location) , Marker 1 , Marker 2, but I am not sure I am doing it right or not ! Here is my code :
self.startMarker.position = CLLocationCoordinate2D(latitude: self.startLatitude, longitude: self.startLongitude)
self.startMarker.icon = #imageLiteral(resourceName: "Pin Start")
self.startMarker.map = self.mapView
self.endMarker.position = CLLocationCoordinate2D(latitude: self.endLatitude, longitude: self.endLongitude)
self.endMarker.icon = #imageLiteral(resourceName: "Pin End")
self.endMarker.map = self.mapView
let southWest = CLLocationCoordinate2DMake(self.startLatitude,self.startLongitude)
let northEast = CLLocationCoordinate2DMake(self.endLatitude,self.endLongitude)
let bounds = GMSCoordinateBounds(coordinate: northEast, coordinate: southWest)
let camera = self.mapView.camera(for: bounds, insets:.zero)
self.mapView.camera = camera!
More Code :
// MARK: - Google Map
private func locationManager(manager: CLLocationManager, didChangeAuthorizationStatus status: CLAuthorizationStatus) {
if status == CLAuthorizationStatus.authorizedWhenInUse {
mapView.isMyLocationEnabled = true
}
}
func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
let newLocation = locations.last
mapView.camera = GMSCameraPosition.camera(withTarget: newLocation!.coordinate, zoom: 14)
mapView.isMyLocationEnabled = true
}
The result is like this :
What I need :
EDITED
if let myLocation = self.mapView.myLocation {
let path = GMSMutablePath()
path.add(myLocation.coordinate)
path.add(self.startMarker.position)
path.add(self.endMarker.position)
let bounds = GMSCoordinateBounds(path: path)
self.mapView.animate(with: GMSCameraUpdate.fit(bounds, withPadding: 40))
}
Showing All Markers with screen bound:
Here I am trying to provide you one simple example, hope this will help you.
Using this, you can show any number of markers on screen.
Example:
let path = GMSMutablePath()
for var i in 0 ..< array.count //Here take your "array" which contains lat and long.
{
let marker = GMSMarker()
let lat = Double(array.objectAtIndex(i).valueForKey(lattitude) as! String)
let long = Double(arrayr.objectAtIndex(i).valueForKey(longitude) as! String)
marker.position = CLLocationCoordinate2DMake(lat!,long!)
path.addCoordinate(marker.position)
marker.map = self.mapView
}
let bounds = GMSCoordinateBounds(path: path)
self.mapView!.animateWithCameraUpdate(GMSCameraUpdate.fitBounds(bounds, withPadding: 30.0))
Can you try the below code, this is converted from ObjC code here is the documentation of includingCoordinate
let bounds = GMSCoordinateBounds()
bounds.includingCoordinate(self.startMarker.position)
bounds.includingCoordinate(self.endMarker.position)
bounds.includingCoordinate(yourCurrentLocationPosition)
self.mapView.animateWithCameraUpdate(GMSCameraUpdate(fitBounds:bounds, padding:20.0f))
func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
showMarkers(locations)
//stop updating location when you find suitable
}
func showMarkers(userLocation: [CLLocation]){
let location1: CLLocationCoordinate2D = CLLocationCoordinate2D(latitude: self.startLatitude, longitude: self.startLongitude)
let location2: CLLocationCoordinate2D = CLLocationCoordinate2D(latitude: self.endLatitude, longitude: self.endLongitude)
let location3: CLLocationCoordinate2D = userLocation[0].coordinate
var locationArray = []
locationArray.append(location1)
locationArray.append(location2)
locationArray.append(location3)
var bounds = GMSCoordinateBounds()
for location in locationArray
{
let latitude = location.valueForKey("latitude")
let longitude = location.valueForKey("longitude")
let marker = GMSMarker()
marker.position = CLLocationCoordinate2D(latitude: latitude, longitude: longitude)
marker.map = self.mapView
bounds = bounds.includingCoordinate(marker.position)
}
let update = GMSCameraUpdate.fitBounds(bounds, withPadding: 100)
mapView.animateWithCameraUpdate(update)
}
Note:
locationArray contains three locations ie. Marker 1, Marker 2, user location.
For someone who is looking for solution with Objective-C, This might help
//Locations
CLLocationCoordinate2D source = CLLocationCoordinate2DMake(19.2880, 72.1587);
CLLocationCoordinate2D userLocation = CLLocationCoordinate2DMake(19.1780, 72.9577);
CLLocationCoordinate2D destination = CLLocationCoordinate2DMake(19.0760, 72.8777);
//Create a GMSMutablePath
GMSMutablePath *path = [GMSMutablePath new];
[path addCoordinate:source];
[path addCoordinate:userLocation];
[path addCoordinate:destination];
//Create bounds
GMSCoordinateBounds *bounds = [[GMSCoordinateBounds alloc]initWithPath:path];
//Update the camera position
[mapview animateWithCameraUpdate:[GMSCameraUpdate fitBounds:bounds]];
I want to calculate the distance from my location to another.
I found this line of code:
let distanceInMeters = location1.distanceFromLocation(location2)
But my problem is that I don't know how to take it from latitude and longitude.
So, you just need to create 2 CLLocation objects from your lat and long and then just call the line of code that you found.
let location1 = CLLocation(latitude: 20.0, longitude: 20.0)
let location2 = CLLocation(latitude: 30.0, longitude: 30.0)
let distanceInMeters = location1.distanceFromLocation(location2)
Also, this will return you distance in meters, not in km.
func locationManager(manager: CLLocationManager!, didUpdateLocations locations: [AnyObject]!) {
var userLocation:CLLocation = locations[0] as! CLLocation
let long = userLocation.coordinate.longitude;
let lat = userLocation.coordinate.latitude;
// use it for your code
}
You can try this function, I use it in my code
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.
