问题
With a CLLocation object (content e.g. latitude = 48.196169, longitude = 11.620237), I try to get the current city and country like:
if(!geocoder) {
geocoder = [[CLGeocoder alloc] init];
}
if (geocoder.geocoding) [geocoder cancelGeocode];
[geocoder reverseGeocodeLocation:lo completionHandler:^(NSArray *placemarks, NSError *error) {
if(devMode) {
NSLog(@"Found placemarks: %@, error: %@", placemarks, error);
}
if (error == nil && [placemarks count] > 0) {
// MY CODE - here placemarks is always (null)
} else {
if(devMode)
NSLog(@"%@", error.debugDescription);
}
}];
mostly, that works great. But in rarely cases, I just get the errors:
PBRequester failed with Error Error Domain=NSURLErrorDomain Code=-1000 "Ungültige URL" UserInfo=0x16f5ff30 {NSUnderlyingError=0x16f57810 "Ungültige URL", NSLocalizedDescription=Ungültige URL}
Found placemarks: (null), error: Error Domain=kCLErrorDomain Code=2 "The operation couldn’t be completed. (kCLErrorDomain error 2.)"
I've absolutely no idea why this happens.

You can use the following code to find the address line, here you have to pass latitude and longitude as a parameter
- (void)findAddress:(CLLocationDegrees)latitude with:(CLLocationDegrees)longitude{
CLLocation *location =[[CLLocation alloc]initWithLatitude:latitude longitude:longitude];
CLGeocoder *geocoder = [[CLGeocoder alloc] init];
[geocoder reverseGeocodeLocation:location completionHandler:^(NSArray *placemarks, NSError *error) {
NSLog(@"Finding address");
if (error) {
NSLog(@"Error %@", error.description);
} else {
NSLog(@"%@",placemarks[0]);
}
}]; }
Here you have to import the following
#import <CoreLocation/CLGeocoder.h>
