cllocationmanager

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

I am using GPS in iphone and it show conformation message for use location service. and i want to trap what user select "Allow" or "No". can any one suggest how i do this? Thank You don't get a direct callback from this alert. However, if the user does not allow Core Location usage, you'll receive a -locationManager:didFailWithError: with a kCLErrorDenied error to your CLLocationManagerDelegate . Since iOS 4.2, you can also listen to -locationManager:didChangeAuthorizationStatus: or check the authorizationStatus of CLLocationManager . This gives you a detailed status. 来源： https://stackoverflow

In my app, if the user not allowed to access their current location, I can recieve that message in the following method - (void)locationManager:(CLLocationManager*)aManager didFailWithError:(NSError*)anError { switch([anError code]) { case kCLErrorLocationUnknown: break; case kCLErrorDenied: { UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Access Denied" message:@"You didn't allow to access your current location" delegate:self cancelButtonTitle:@"Ok" otherButtonTitles:nil]; [alert show]; break; } } } How to ask the user permission for the second time? I searched and got the answer

I have my object set as the locationManager's delegate, and the didChangeAuthorizationStatus method is called, which does this: func locationManager(manager: CLLocationManager!, didChangeAuthorizationStatus status: CLAuthorizationStatus) { if status == CLAuthorizationStatus.AuthorizedWhenInUse { self.locationManager.startUpdatingLocation() } } I also have this method, which never gets called following this: func locationManager(manager: CLLocationManager!, didUpdateLocations locations: [AnyObject]!) { if locations.count == 0 { return } //Do stuff } Any thoughts as to why this might not be

I have created a application which uses mapview. For maps I used MKMapKit library. Everything works fine when user selects "Allow" button on alert window. But I want to detect when user selects "Don't Allow". I found a delegate which most of the developers used (void)locationManager:(CLLocationManager *)manager didFailWithError:(NSError *)error but the delegate does not get called. Maybe I am missing something. In my header (.h) file I have implemented MKMapViewDelegate . Is there anything else I need to do? Do I need to add some extra classes like CLLocationManager or else. Thanks, In order

I'm developing an iOS app based on the map and location tracking. When the user first boots the app it asks for permission to track location etc. just fine. The only problem is while it's doing that, I have code setting up the initial map view and other location-based variables before the user has clicked OK. I've found I can put these initiation steps after a while loop that waits for the user to change the location manager's permissions as below but this can't possibly be best practice, not to mention it leads to some strange behavior in the transition between the splash screen and the map:
