How to search locations near about 10 km from user location

Today I have write about to getting particular area.

First getting the list of location save into array and passed this array to below function

01	-(NSArray *)findNearMe:(NSArray *)lounges {

02	NSMutableArray *arNearme = [NSMutableArray array];

03

04	CLLocation *currentLocation;

05

06	for(NSDictionary *d in lounges)

07

{

08	if([[LocationController sharedInstance] locationKnown] == YES)

09

{

10	currentLocation = [[LocationController sharedInstance] currentLocation];

11

}

12

else

13

{

14	currentLocation = [[CLLocation alloc] initWithLatitude:29.33891 longitude:48.077202];

15

}

16	//        NSLog(@"Current Location : %@",[currentLocation description]);

17

18	CGFloat latitude=[[d valueForKey:@"latitude"] floatValue];

19	CGFloat longitude=[[d valueForKey:@"longitude"] floatValue];

20	CLLocation *newPinLocation=[[CLLocation alloc] initWithLatitude:latitude longitude:longitude];

21	double distanceValue=[currentLocation distanceFromLocation:newPinLocation];

22

23	if(distanceValue/1000.0<=DISTANCE_RADIUS) {

24	//            NSLog(@"Distance value : %f",distanceValue);

25	[arNearme addObject:d];

26

}

27

}

28	//    NSLog(@"Near Me Lounges : %d\n%@",[arNearme count], [arNearme description]);

29

30	return  arNearme;

31

}

Cheers!!
