I am trying to add map annotation, but when i try to run the app, the map annotation doesnt show, and give error message.
Add Map Annotation[3668:68848] Could not inset legal attribution from
corner 4
actually I just follow along a tutorial on Youtube in here https://www.youtube.com/watch?v=hRextIKJCnI , in swift3 this code seems work, but I don't know why it doesnt work in me. I am using swift 4 and Xcode 9.2
I have tried a solution from stack overflow but it doesn't work in me, in here Could not inset legal attribution from corner 4 swift
What went wrong in here?
import UIKit
import MapKit
class ViewController: UIViewController {
#IBOutlet weak var mapKitView: MKMapView!
override func viewDidLoad() {
super.viewDidLoad()
let span : MKCoordinateSpan = MKCoordinateSpanMake(0.001, 0.001)
let location : CLLocationCoordinate2D = CLLocationCoordinate2DMake(-6.239116, 106.789415)
let region : MKCoordinateRegion = MKCoordinateRegionMake(location, span)
mapKitView.setRegion(region, animated: true)
let annotation = MKPointAnnotation()
annotation.title = "My Shop"
annotation.subtitle = "Come visit here"
mapKitView.addAnnotation(annotation)
}
}
You are saying:
let annotation = MKPointAnnotation()
annotation.title = "My Shop"
annotation.subtitle = "Come visit here"
mapKitView.addAnnotation(annotation)
And that's all you're saying. But... That annotation has no coordinate! So how do you imagine the map can possibly know where it's supposed to go?

I want to plot a specific point on the map having the lat and lon from an api.
Program flow:
Get LAT & LON from api (done)
Ping api again via timer after every 5 seconds to get the latest location (done)
Plot location with retrieved LAT & LON on map
The issue is every code on the net has to do with 2 points, so user loc and destination loc. I cant seem to get it to work without user loc. I have however coded this to plot the location. However, with this when I touch the map, the map zooms out. Another issue is when I get another point the previous one also remains on the screen. (for testing purpose I hard coded the lat and lon but when I connect the api code that refreshes, prior points remain and the map code is the same as this. The lat and lon are passed via func parameters in createAnnotation().)
My code:
import UIKit
import MapKit
class ViewController: UIViewController, MKMapViewDelegate {
#IBOutlet weak var mapView: MKMapView!
override func viewDidLoad() {
super.viewDidLoad()
mapView.delegate = self // or connect in storyboard
createAnnotation()
}
func createAnnotation(){
let annotations = MKPointAnnotation()
annotations.coordinate = CLLocationCoordinate2D(latitude: 41.87369, longitude: -87.813293)
mapView.addAnnotation(annotations)
}}
How Do I plot the coordinates properly? and then delete the prior and show the new one?.
For the "previous one also remains on the screen" problem: don't keep making a new annotation and calling addAnnotation if you don't want to keep adding new annotations. Instead, keep hold of the annotation that you add, and move it later using its coordinate property. Something like this maybe:
class ViewController: UIViewController, MKMapViewDelegate {
#IBOutlet weak var mapView: MKMapView!
var annotationForThing: MKPointAnnotation?
var coordinateOfThing: CLLocationCoordinate2D? {
didSet {
guard let newCoord = coordinateOfThing else {
if let existing = annotationForThing {
mapView.removeAnnotation(existing)
}
return
}
if let existing = annotationForThing {
existing.coordinate = coordinateOfThing
}
else {
let newAnnotation = MKPointAnnotation()
newAnnotation = coordinateOfThing
mapView.addAnnotation(newAnnotation)
annotationForThing = newAnnotation
}
}
}
override func viewDidLoad() {
super.viewDidLoad()
mapView.delegate = self // or connect in storyboard
}
I'm using this function to change the location of the map marker based on user selection:
let annotation = MKPointAnnotation() //global reused annotation object
func setPin(mapView: MKMapView, longitude: Double, latitude: Double, title: String) {
annotation.coordinate = CLLocationCoordinate2D(latitude: latitude, longitude: longitude)
annotation.title = title
mapView.addAnnotation(annotation)
}
The coordinates and title changes repeatedly, so I'm a little concerned if this is the correct approach. The MKPointAnnotation object is instantiated only once, as a global, and only its contents are updated when the setPin() function is called. So far, it's been working without issue, besides the glitch with the simulator not refreshing/rendering the title sometimes.
Would doing this cause any leaks? Am I missing any steps to free the obejct or remove it from the map before reusing it, perhaps?
TIA.
So I want to make a button that sets an annotation at your current location. I have all of my map stuff and core location code working it is just the button. Here is my button function code:
#IBAction func addAnnotation(_ sender: UIButton) {
CLLocationManager().startUpdatingLocation()
let annotation = MKPointAnnotation()
// Set the annotation by the lat and long variables
annotation.coordinate = CLLocationCoordinate2D(latitude: 0.0, longitude: 0.0)
annotation.title = "User location"
self.map.addAnnotation(annotation)
}
Right now, I When I run this code I get a SIGABRT Error in my AppDelegate.swift. Please Help.
Facing an issue using xcode v7.2.1 and the ios simulator v9.2 .
The problem i'm facing is that the map appears blank when i run the application.
The grid lines appear for a second and then it's just blank. I've tried searching for a solution but haven't found any that have worked.
import UIKit
import MapKit
class ViewController: UIViewController, MKMapViewDelegate {
#IBOutlet var map: MKMapView!
override func viewDidLoad() {
super.viewDidLoad()
//maps integration
let longitude : CLLocationDegrees = 17.486374
let latitude : CLLocationDegrees = 78.543345
let longDelta : CLLocationDegrees = 0.1
let latDelta : CLLocationDegrees = 0.1
let location : CLLocationCoordinate2D = CLLocationCoordinate2DMake(latitude, longitude)
let span : MKCoordinateSpan = MKCoordinateSpanMake(latDelta, longDelta)
let region : MKCoordinateRegion = MKCoordinateRegionMake(location, span)
map.setRegion(region, animated: true)
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
}
it's just a picture of the simulator once the app is run.
This is what i meant when i said blank incase it wasn't clear.
Thanks in advance !
I think it's possible you may have confused your latitude and longitude values. The lat/long you have now takes you to Svalbard and Jan Mayen (a couple of remote islands in the middle of nowhere, north of Norway), but if you switch the lat and long you get Hyderabad in India.
Just Print the Value.
it might be 0,0 and your location would be on the sea.
please make sure that your location have valid location. longitude and latitude.
This case always happen when you trying to update the map on ViewDidload instead of view Didappear.
I am using Google Maps SDK for iOS version: 1.10.17867.0 in my app via pod. But when I initialise the map at a particular position, all the titles and map starts flickering.
Example Code (swift):
import UIKit
import GoogleMaps
class ViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
self.view.backgroundColor = UIColor.whiteColor();
var camera = GMSCameraPosition.cameraWithLatitude(19.0176147, longitude: 72.8561644, zoom:18)
// even try this: 28.6469655, longitude: 77.0932634, zoom:10
var mapView = GMSMapView.mapWithFrame(CGRectZero, camera:camera)
var marker = GMSMarker()
marker.position = camera.target
marker.snippet = "Hello World"
marker.appearAnimation = kGMSMarkerAnimationPop
marker.map = mapView
self.view = mapView
}
}
I have figured out the reason.
If you are using an incorrect google maps api key, or correct key with insufficient permissions, then this will happen. It was the latter reason for us.
For further reading, documentation link, although the said behaviour is not mentioned anywhere. It should rather log an error message.
