See more Geolocation Examples

Demonstrates how to lookup Geolocation data for an IPv4 address using the api.db-ip.com REST API. Objective-C

#import <CkoHttp.h>
#import <NSString.h>
#import <CkoJsonObject.h>

BOOL success = NO;

// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

CkoHttp *http = [[CkoHttp alloc] init];

// Lookup an IPv4 address: 149.250.207.170  (this was a randomly chosen address)
NSString *jsonStr = [http QuickGetStr: @"http://api.db-ip.com/v2/free/149.250.207.170"];
if (http.LastMethodSuccess == NO) {
    NSLog(@"%@",http.LastErrorText);
    return;
}

CkoJsonObject *json = [[CkoJsonObject alloc] init];
json.EmitCompact = NO;
success = [json Load: jsonStr];

NSLog(@"%@",[json Emit]);
