iphone ask for Current location permission again

Question

Case: For current location, the user selected "Dont allow" on app install, so is there a way that I can ask again for the user location and trigger the native iphone alert for current location??

I seen some posts on stackoverflow but there are old, is there a solution now to call in new sdk or someone found a way,

Answer 1

Unfortunately you can't do that. One thing you can do is to prompt the user to change the location settings.

if (![CLLocationManager locationServicesEnabled]) 
{
    UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Location Service Disabled" 
                                                        message:@"To re-enable, please go to Settings and turn on Location Service for this app." 
                                                       delegate:nil 
                                              cancelButtonTitle:@"OK" 
                                              otherButtonTitles:nil];
        [alert show];
}

in ios8, apple has introduced a UIApplicationOpenSettingsURLString constant which is the location of the device's "settings" view.

you can code the following (in swift) to direct the user to the settings view:

switch CLLocationManager.authorizationStatus() {
    case .AuthorizedWhenInUse, .Restricted, .Denied:
        let alertController = UIAlertController(
            title: "Background Location Access Disabled",
            message: "In order to be notified, please open this app's settings and set location access to 'Always'.",
            preferredStyle: .Alert)

        let cancelAction = UIAlertAction(title: "Cancel", style: .Cancel, handler: nil)
        alertController.addAction(cancelAction)

        let openAction = UIAlertAction(title: "Open Settings", style: .Default) { (action) in
            if let url = NSURL(string:UIApplicationOpenSettingsURLString) {
                UIApplication.sharedApplication().openURL(url)
            }
        }
        alertController.addAction(openAction)

        self.presentViewController(alertController, animated: true, completion: nil)
}
