如何从以下代码中提取lat和long？

Question

如何从以下代码中提取lat和long：

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);

}

从nslog输出我得到：

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

我想得到lat和lon并将它们存储到变量中。

Answer 1

CLLocationCoordinate2D coordinate = placemark.location.coordinate

然后：

coordinate.longitude
coordinate.latitude
