如何從下面的代碼中提取lat和long？

Question

我如何提取lat和長從follwoing代碼：

CLGeocoder *geocoder = [CLGeocoder new]; 
[geocoder geocodeAddressString:city completionHandler:^(NSArray *placemarks, NSError *error) { 
if (error) { 
    NSLog(@"Error: %@", [error localizedDescription]); 
} 

if ([placemarks count] > 0) { 

    CLPlacemark *placemark = [placemarks lastObject]; 
    NSLog(@"Location is: %@", placemark.location); 

}

從NSLog的輸出我得到：

Location is: <+45.46368100,+9.18817140> +/- 100.00m (speed -1.00 mps/course -1.00) @ 25/09/2013 11:04:20 British Summer Time 

我想只得到lat和並將它們存儲到變量中。

Answer 1

CLLocationCoordinate2D coordinate = placemark.location.coordinate 

然後：

coordinate.longitude 
coordinate.latitude
