如何检索用户当前的城市名称？

Answer 1

从 iOS 5 开始，MKReverseGeoCoder 已弃用!

所以你想将 CLGeocoder 与 CLLocationManager 一起使用，非常简单且适用于 block 。

示例:

- (void)locationManager:(CLLocationManager *)manager
    didUpdateToLocation:(CLLocation *)newLocation
           fromLocation:(CLLocation *)oldLocation
{
   [self.locationManager stopUpdatingLocation];

   CLGeocoder * geoCoder = [[CLGeocoder alloc] init];
    [geoCoder reverseGeocodeLocation:newLocation
                   completionHandler:^(NSArray *placemarks, NSError *error) {
                       for (CLPlacemark *placemark in placemarks) {
                           .... = [placemark locality];
                       }
                   }];
}

编辑:除了 for in 循环，您还可以这样做:

NSString *locString = placemarks.count ? [placemarks.firstObject locality] : @"Not Found";
