Im using Map Kit and Core Location now and need to to get location information from zip code or city/state . Is there any way to do it?
You can use the CLGeocoder
class which supports converting an address to a coordinate, and the reverse. For example:
[geocoder geocodeAddressString:@"<postcode here>"
completionHandler:^(NSArray* placemarks, NSError* error){
for (CLPlacemark* aPlacemark in placemarks)
{
// Process the placemark.
}
}];
There are a bunch of different methods you may want to use. You can limit the search to a particular region, for example.
You can use https://thezipcodes.com/ to get location from ZIP Code.
To integrate with your website follow http://thezipcodes.com/docs
Use this
-(CLLocationCoordinate2D) getLocationFromAddressString:(NSString*) addressStr {
double latitude = 0, longitude = 0;
NSString *esc_addr = [addressStr stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
NSString *req = [NSString stringWithFormat:@"http://maps.google.com/maps/api/geocode/json?sensor=false&address=%@", esc_addr];
NSString *result = [NSString stringWithContentsOfURL:[NSURL URLWithString:req] encoding:NSUTF8StringEncoding error:NULL];
if (result) {
NSScanner *scanner = [NSScanner scannerWithString:result];
if ([scanner scanUpToString:@"\"lat\" :" intoString:nil] && [scanner scanString:@"\"lat\" :" intoString:nil]) {
[scanner scanDouble:&latitude];
if ([scanner scanUpToString:@"\"lng\" :" intoString:nil] && [scanner scanString:@"\"lng\" :" intoString:nil]) {
[scanner scanDouble:&longitude];
}
}
}
CLLocationCoordinate2D center;
center.latitude = latitude;
center.longitude = longitude;
return center;
}
This method returns Coordinates using google api when you pass address as argument in this .
