How to convert NSMutableArray to CLLocationCoordinate2D

Question

I have NSMutableArray:

        userCoordinates = [[d objectForKey:@"geo"] objectForKey:@"coordinates"];

        NSLog(@"%@",userCoordinates);

NSLog shows:

(
    "19.365367",
    "-99.159887"
)

Then I need to convert this array to CllocationCoordinate2D to use it for create annotation. Sorry my english. Thanks.

It seems that your array contains two NSString objects - to convert them to the appropriate floating-point numbers, use the doubleValue method of NSString :

double lat = [(NSString *)[userCoordinates objectAtIndex:0] doubleValue];
double lon = [(NSString *)[userCoordinates objectAtIndex:1] doubleValue];

CLLocationCoordinate2D coords = (CLLocationCoordinate2D){ lat, lon };
