Question

I am trying two draw route between two location,For that I Fetch all the points from Google Map API Web Service.(JSON Output Format). After parsing JSON Data and De cording points i stored all points on NSMutableArray.
Each array of index contains this type of values.

"<+10.90180969, +76.19167328> +/- 0.00m (speed -1.00 mps / course -1.00) @ 12/04/12 10:18:10 AM India Standard Time",

Now i want to separate latitude and longitude values.

latitude  : +10.90180969
longitude : +76.19167328

How to get this values from each index of array?

Answer 1

Here is something in a very crude form and I guess its a brute solution

NSString* str =     @"<+10.90180969, +76.19167328> +/- 0.00m (speed -1.00 mps  course -1.00) @ 12/04/12 10:18:10 AM India Standard Time";
NSArray* arr = [str componentsSeparatedByCharactersInSet:[NSCharacterSet characterSetWithCharactersInString:@"<>"]];

if ([arr count] > 1) {
   NSString* coordinateStr =  [arr objectAtIndex:1];        
   NSArray* arrCoordinate = [coordinateStr componentsSeparatedByString:@","];        
    NSLog(@"%@",arrCoordinate);
}

Looking at the string it shows that you are printing the description of a CLLocation object “someObject” , You can also access the latitude and longitude such as

   CLLocationCoordinate2D location = [someObject coordinate];
    NSLog(@" \nLatitude: %.6f \nLongitude: %.6f",location.latitude,location.longitude);

OutPut will be : Latitude: 28.621873 Longitude: 77.388897

but this won’t give you the signs i.e “+” , or “-“

Hope it helps.
