Resolve a Hostname to an IP Address

See more Socket/SSL/TLS Examples

Demonstrates Socket.DnsLookup, which resolves a hostname and returns one numeric IP address.

#import <CkoSocket.h>
#import <NSString.h>

CkoSocket *socket = [[CkoSocket alloc] init];

//  Resolve a hostname to a numeric IP address, waiting up to 5 seconds.
NSString *ipAddress = [socket DnsLookup: @"example.com" maxWaitMs: [NSNumber numberWithInt: 5000]];
if (socket.LastMethodSuccess == NO) {
    NSLog(@"%@",socket.LastErrorText);
    return;
}

NSLog(@"%@%@",@"Resolved IP address: ",ipAddress);
