How to use CoreLocation in iOS8/ios9? - ios

Question

I have programmed a project which use CoreLocation. In this project, I designed a button to get location. However it has no reaction when I click. Someone said it had changed in iOS 8. And I do what he said. But it did't work. Here is my git link: https://github.com/dwjdwj1216/MyLocations

Answer 1

Do like this in your CurrentLocationViewController, getLocation Method change like this:-
locationManager = [[CLLocationManager alloc] init];
[locationManager setDelegate:self];
[locationManager setDesiredAccuracy:kCLLocationAccuracyBestForNavigation];
if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 8.0) {
[locationManager requestAlwaysAuthorization];
}
if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 9) {
_locationManager.allowsBackgroundLocationUpdates = YES;
}
[locationManager setDistanceFilter:10.0f];
[locationManager startUpdatingLocation];
[locationManager startMonitoringSignificantLocationChanges];

To Get Current Location, Follow step..
First Set Two lines in .Plist File
NSLocationAlwaysUsageDescription : Allow location
NSLocationWhenInUseUsageDescription : Allow location
// AppDelegate.h
#import <CoreLocation/CoreLocation.h>
#property (nonatomic,retain) CLLocationManager *locationManager;
#import "AppDelegate.m"
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
// Override point for customization after application launch.
[self getCurrentLocation];
}
#pragma mark - CLLocatin delegate && Location Methdos
-(void)getCurrentLocation {
locationManager = [[CLLocationManager alloc] init];
locationManager.delegate = self;
// To calculate loaction on 500 meters
/* CLLocationDistance kilometers = 0.5 1000.0; //user will be notified when distance is changed by 40km from current distance
locationManager.distanceFilter = kilometers; */
#ifdef __IPHONE_8_0
if (IS_OS_8_OR_LATER)
{
[locationManager requestAlwaysAuthorization];
}
#endif
[locationManager startUpdatingLocation];
}
- (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation {
//NSLog(#"didUpdateToLocation: %#", newLocation);
CLLocation *currentLocation = newLocation;
if (currentLocation != nil) {
[locationManager stopUpdatingLocation];
[self getCurrentCountry];
}
}
- (void)locationManager:(CLLocationManager*)aManager didFailWithError:(NSError *)anError {
switch([anError code])
{
case kCLErrorNetwork: // general, network-related error
{
}
break;
case kCLErrorDenied:{
}
break;
default:
{
}
break;
}
}
-(void)getCurrentCountry {
CLGeocoder *geoCoder = [[CLGeocoder alloc] init];
[geoCoder reverseGeocodeLocation:locationManager.location
completionHandler:^(NSArray *placemarks, NSError *error) {
if (error == nil && [placemarks count] > 0)
{
NSLog(#"Current country: %#", [[placemarks objectAtIndex:0] country]);
NSLog(#"Current country code: %#", [[placemarks objectAtIndex:0] ISOcountryCode]);
NSLog(#"CountryCode=%#",GetContryCode);
SetContryCode
setBoolForCountryCode(YES);
NSLog(#"CountryCode=%#",GetContryCode);
}
}];
}
