Not getting appropriate Latitude Longitude - ios

Question

I am a iOS application developer. I am working with Location Manager.
For every 5 seconds I am capturing the latitude and longitude and storing the CLLocation object in array. The lat and long is not completely correct when I am trying to draw those location in Map.
My code is following below:
- (void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray *)locations{//ios6&+
CLLocation *loc;
NSInteger objCount = [locations count];
if (objCount >= 1) {
loc = [locations objectAtIndex:objCount - 1];
NSArray *Arr_TotalTime = [Str_TotalTime componentsSeparatedByString:#":"];
[ArrayOfLocations addObject:loc];
}
}
Any one can please give me more info to get ACTUAL location (lat, long) from didupdatelocation method.
Any help will be highly appreciated.

Answer 1

Depending on how you set up your location manager, the accuracy will vary.
Try something like this:
Location Manager
_locationManager = [[CLLocationManager alloc] init];
_locationManager.delegate = self;
_locationManager.desiredAccuracy = kCLLocationAccuracyBestForNavigation;
_locationManager.activityType = CLActivityTypeAutomotiveNavigation;
_locationManager.distanceFilter = kCLDistanceFilterNone;
Method
- (void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray *)locations
{
CLLocation *newLocation = [locations lastObject];
NSDate *eventDate = newLocation.timestamp;
NSTimeInterval howRecent = [eventDate timeIntervalSinceNow];
if ((abs(howRecent) <= 5) && (newLocation.horizontalAccuracy > 0) && (newLocation.verticalAccuracy > 0) && (newLocation.horizontalAccuracy < 100) && (newLocation.verticalAccuracy < 100))
{
[ArrayOfLocations addObject:newLocation];
}
else
{
// received bad signal
}
}

You can use CoreLocation to get the longitude and latitude.
Include framework:
Click your project in navigator.
Click the plus button under "link binary with libraries"
Add Corelocation to your project.
Import the header file:
import
Declare CLLocationManager:
CLLocationManager *locationManager;
initialize locationManager:
- (void)viewDidLoad
{
locationManager = [[CLLocationManager alloc] init];
locationManager.distanceFilter = kCLDistanceFilterNone;
locationManager.desiredAccuracy = kCLLocationAccuracyHundredMeters;
[locationManager startUpdatingLocation];
}
Then, use
float latitude = locationManager.location.coordinate.latitude;
float longitude = locationManager.location.coordinate.longitude;
