GCDAsyncUdpSocket does not compile for iOS

I use this library: https://github.com/robbiehanson/CocoaAsyncSocket

There are examples for TCP on the iphone but not UDP. I think that everything should be just the same. Here is my code:

#import <UIKit/UIKit.h>
@class GCDAsyncUdpSocket;

@interface ThirdViewController : UIViewController
{
    GCDAsyncUdpSocket *udpSocket;
}

.m:

#import "ThirdViewController.h"
#import "DDLog.h"
#import "DDTTYLogger.h"
#import "GCDAsyncUdpSocket.h"

static const int ddLogLevel = LOG_LEVEL_VERBOSE;

@implementation ThirdViewController

- (void)viewDidLoad
{
    [DDLog addLogger:[DDTTYLogger sharedInstance]];
    udpSocket = [[GCDAsyncUdpSocket alloc] initWithDelegate:self delegateQueue:dispatch_get_main_queue()];
}

But when compiling I get the errors:

Undefined symbols for architecture i386: "_OBJC_CLASS_$_DDLog",

referenced from: objc-class-ref in ThirdViewController.o "_OBJC_CLASS_$_DDTTYLogger", referenced from: objc-class-ref in ThirdViewController.o "_OBJC_CLASS_$_GCDAsyncUdpSocket", referenced from: objc-class-ref in ThirdViewController.o ld: symbol(s) not found for architecture i386

What is wrong? Examples from the library compiled without errors.

(Build Phases >> Link Binary With Libraries) Add CocoaLumberjack as optional dependency.

You have to link CFNetwork.framework or if have it you're propably working on Automatic Reference Counter, turon off ARC for GCDAsyncUdpSocket using -fno-objc-arc
