mapkit

I need to display an MKOverlay on a map, but can't get it to actually appear. I'm following the example from Apple's Location Awareness Programming Guide and the overlay wont display. Any help would be greatly appreciated, this is the first iPhone app I've made, so I might be missing something simple. NavViewController.h #import <UIKit/UIKit.h> #import <MapKit/MapKit.h> @interface NavViewController : UIViewController <MKMapViewDelegate> { } @property (weak, nonatomic) IBOutlet MKMapView *mapView; @end NavViewController.m #import "MSUNavViewController.h" #import <CoreLocation/CoreLocation.h> -

I have an unreproducible crash on iOS 7 only. I'm making heavy use of MKOverlayRenderer to draw shapes on the map. This crash does not happen on iOS 6. Any ideas of what this might be related to will be useful.

I have a normal map in my iOS app where "Shows Users Location" is enabled - meaning I have my normal blue dot on the map, showing my position and accuracy info. The callout is disabled in code. But I also have custom MKAnnotationViews that are plotted around the map which all have custom callouts. This is working fine, but the problem is that when my location is on the location of a MKAnnotationView, the blue dot (MKUserLocation) intercepts the touch, so the MKAnnotationView doesn't get touched. How can I disable the user interaction on the blue dot so that the touches are intercepted by the

I was going through the sample example of MapKit and CoreLocation framework. I found these two structs ( MKCoordinateSpan and CLLocationCoordinate2D ) which are similar in declaration. How are these different in functionality, can someone please site an example (using both) to clear their meanings. Thanks! MKCoordinateSpan defines a span , i.e. a delta, in the latitude and longitude directions to show on a map. Along with a point you can then define a region to display on a map. CLLocationCoordinate2D defines a single point in the latitude and longitude coordinate system. For example: |<----

I want my program to display the users location on the map. It was working at first then randomly stopped so i added the code below to try to fix it but I'm having problems. Thanks in advance! override func viewDidLoad() { super.viewDidLoad() self.locationManager.delegate = self self.locationManager.desiredAccuracy = kCLLocationAccuracyBest if CLLocationManager.locationServicesEnabled() { let status: CLAuthorizationStatus = CLLocationManager.authorizationStatus() if status == CLAuthorizationStatus.NotDetermined { locationManager.requestAlwaysAuthorization() } } else { print("locationServices

I have one of my application, that is created in Xcode 8. I have used CoreLocation and MapKit in that app. I have update app with latest iOS till now. and it was working fine. Now I am updating application with iOS 1 . So I hvae opened app with Xcode 11.0 and updated all the required code. Also updated setting that is suggested by Xcode "Perform Changes" and all that. Now I run application, but I am getting error like : Compiler error: Invalid library file . I have searched lot, but can't find any solution. Is this a bug in new Xcode or new iOS ? Is there anything I have to do extra changes or

I'm developing an app that will focus heavily on giving users routes and turn-by-turn directions while driving. It is important that they stay within the app during their drive, so I really don't want to make them leave the app and go to the built-in Maps app. I have been doing a lot of research lately on how to include this functionality, and it is widely known that it is not easy, since Apple doesn't include this functionality in the SDK out of the box. It looks like my options are: For providing routes (and directions) from one place to another Use a UIWebView and load some web-based maps
