Q:

how to get current location lat long in ios 8?

my issue is not get current location latitude and longitude in ios 8. i tried to set key in .plist file for ios 8 but but not call this method- didUpdateToLocation: please help this on issue.
my code is:-
- (void)viewDidLoad

{
[super viewDidLoad];
self.locationManager = [[CLLocationManager alloc] init];
self.locationManager.delegate = self;

if(IS_OS_8_OR_LATER) {
    //[self.locationManager requestWhenInUseAuthorization];
    [self.locationManager requestWhenInUseAuthorization];
    [self.locationManager startUpdatingLocation];
}

}

A:

#define IS_OS_8_OR_LATER ([[[UIDevice currentDevice] systemVersion] floatValue] >= 8.0)
-(void)viewDidLoad
{  
[super viewDidLoad];
self.locationManager = [[CLLocationManager alloc] init];

self.locationManager.delegate = self;
if(IS_OS_8_OR_LATER){
    NSUInteger code = [CLLocationManager authorizationStatus];
    if (code == kCLAuthorizationStatusNotDetermined && ([self.locationManager respondsToSelector:@selector(requestAlwaysAuthorization)] || [self.locationManager respondsToSelector:@selector(requestWhenInUseAuthorization)])) {
        // choose one request according to your business.
        if([[NSBundle mainBundle] objectForInfoDictionaryKey:@"NSLocationAlwaysUsageDescription"]){
            [self.locationManager requestAlwaysAuthorization];
        } else if([[NSBundle mainBundle] objectForInfoDictionaryKey:@"NSLocationWhenInUseUsageDescription"]) {
            [self.locationManager  requestWhenInUseAuthorization];
        } else {
            NSLog(@"Info.plist does not contain NSLocationAlwaysUsageDescription or NSLocationWhenInUseUsageDescription");
        }
    }
}
[self.locationManager startUpdatingLocation];
}

#pragma mark - CLLocationManagerDelegate
- (void)locationManager:(CLLocationManager *)manager didFailWithError:(NSError *)error
{
    NSLog(@"didFailWithError: %@", error);
    UIAlertView *errorAlert = [[UIAlertView alloc]
                               initWithTitle:@"Error" message:@"Failed to Get Your Location" delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil];
    [errorAlert show];
}

- (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation
{
    NSLog(@"didUpdateToLocation: %@", newLocation);
    CLLocation *currentLocation = newLocation;
    
    if (currentLocation != nil) {
        longitudeLabel.text = [NSString stringWithFormat:@"%.8f", currentLocation.coordinate.longitude];
        latitudeLabel.text = [NSString stringWithFormat:@"%.8f", currentLocation.coordinate.latitude];
    }
}

In iOS 8 you need to do two extra things to get location working: Add
a key to your Info.plist and request authorization from the location
manager asking it to start. There are two Info.plist keys for the new
location authorization. One or both of these keys is required. If
neither of the keys are there, you can call startUpdatingLocation but
the location manager won’t actually start. It won’t send a failure
message to the delegate either (since it never started, it can’t
fail). It will also fail if you add one or both of the keys but forget
to explicitly request authorization. So the first thing you need to do
is to add one or both of the following keys to your Info.plist file:

NSLocationWhenInUseUsageDescription
NSLocationAlwaysUsageDescription

Both of these keys take a string

which is a description of why you need location services. You can
enter a string like “Location is required to find out where you are”
which, as in iOS 7, can be localized in the InfoPlist.strings file.
