Getting Same Latitude and Longitude in Multiple Locations for Mapkit in iPhone

Question

Hello I am working on Mapkit in an iPhone Application . I am actaually showing multiple numbers of locations. The problem is that i am getting the same Lat. and Long.. for all of the locations. The area of the location is Singapore . I am showing number of universities in the location area.

My code is below

-(CLLocationCoordinate2D) addressLocation:(int)num{

 NSString *urlString = [NSString stringWithFormat:@"http://maps.google.com/maps/geo?q=%@&output=csv",[[address objectAtIndex:num] stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];

 NSString *locationString = [NSString stringWithContentsOfURL:[NSURL URLWithString:urlString]];
 NSArray *listItems = [locationString componentsSeparatedByString:@","];


 double latitude ;
 double longitude ;

 if([listItems count] >= 4){     
    latitude = [[listItems objectAtIndex:2] doubleValue];
    longitude = [[listItems objectAtIndex:3] doubleValue];
 }
 else {
  //Show error
 }

In the List Items i could see only the same values for latitude and longitude

200,
1,
"1.3520830",
"103.8198360".

If you have any solution for the same than please let me know
