xmppframework - enable log for send / receive

Question

I'm working on chat app using xmppframework in iOS. The framework contain sample demo that print send and receive log for xml. Now I implement same things in my app but no log is showing.

Example of log for sample app

2014-05-08 16:34:15:993 iPhoneXMPP[4839:1403] SEND: <?xml version='1.0'?>
2014-05-08 16:34:15:994 iPhoneXMPP[4839:1403] SEND: <stream:stream xmlns='jabber:client' xmlns:stream='http://etherx.jabber.org/streams' version='1.0' to='meinantrieb.net'>
2014-05-08 16:34:16:384 iPhoneXMPP[4839:3503] RECV: <stream:stream xmlns="jabber:client" xmlns:stream="http://etherx.jabber.org/streams" id="1364620848" from="meinantrieb.net" version="1.0" stream1:lang="en"/>

Code For Adding Log in AppDelegate.m

#import "DDLog.h"
#import "DDTTYLogger.h"

// Log levels: off, error, warn, info, verbose
#if DEBUG
static const int ddLogLevel = LOG_LEVEL_VERBOSE;
#else
static const int ddLogLevel = LOG_LEVEL_INFO;
#endif

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    // Configure logging framework
    [DDLog addLogger:[DDTTYLogger sharedInstance]];
}

Any help or suggestion will be well appreciated.

Answer 1

use this line to replace the code of configuring logging framework

[DDLog addLogger:[DDTTYLogger sharedInstance] withLogLevel:XMPP_LOG_FLAG_SEND_RECV]

it is copied from the demo code of XMPPFramework

Answer 2

With Swift 3.x, DDLog log levels are an enum, so it's not immediately possible to apply the XMPPFramework log levels.

One can enable all log messages:

DDLog.add(DDTTYLogger.sharedInstance, with: .all)
