ios - CLGeocoder 从给定位置反向地理编码

Question

给定经度和纬度不是我的当前位置，我如何使用 GLGeocoder 执行反向地理编码查找？

self.geoCoder = [[CLGeocoder alloc] init];
self.locationManager = [[CLLocationManager alloc] init];
self.locationManager.delegate = self;
//    [self.locationManager startUpdatingLocation];

[self.geoCoder reverseGeocodeLocation: locationManager.location completionHandler: ^(NSArray *placemarks, NSError *error) {
//        [self.locationManager stopUpdatingLocation];

     CLPlacemark *placemark = [placemarks objectAtIndex:0];
    // Long address
    // NSString *locatedAt = [[placemark.addressDictionary valueForKey:@"FormattedAddressLines"] componentsJoinedByString:@", "];
    // Short address
    NSString *locatedAt = [placemark subLocality];

     cell.textLabel.text = spot.name;
     cell.detailTextLabel.text = [NSString stringWithFormat:@"Cab no: %@, spotted at %@", spot.cabno, locatedAt];
 }];

显然只会对我的位置进行地理编码，但我需要明确设置要反转的经度和纬度。

我从来没有尝试过这个，但是你不能创建你自己的 CLLocation 对象吗？

如果您知道当前的经度和纬度，您可以 -

CLLocation *location = [[CLLocation alloc]initWithLatitude:someValue longitude:someValue];
[self.geoCoder reverseGeocodeLocation: location completionHandler: ^(NSArray *placemarks, NSError *error) {
    //do something
});
