NBULog
Log framework based on CocoaLumberjack. Adds dynamic log levels, modules' support and eases usage.
Was part of NBUCore.
Demo
iOS and OS X demo projects are included in the repository.
Features
Dynamic Log Levels
Instead of handling a ddLogLevel variable set you app log level dynamically. Also works with third party libraries that support NBULog.
[NBULog setAppLogLevel:DDLogLevelInfo];
[NBULog setKitLogLevel:DDLogLevelWarning]; // When using NBUKitModules
By default all your sources to APP_MODULE_DEFAULT but you can define your own modules in your prefix.pch file.
// Custom log modules
#define APP_MODULE_NETWORK 1 // APP_MODULE_DEFAULT = 0
#define APP_MODULE_OTHER 2Then just redefine LOG_MODULE for the files that belong to one of your custom modules.
#import "MockNetworkModule.h"
// Define log module for this file
#undef LOG_MODULE
#define LOG_MODULE APP_MODULE_NETWORKAlso you log a message for a different module than the one your file belongs to:
// Send an extra message for another module
NBULogInfoWithModule(APP_MODULE_OTHER, @"Log message from a APP_MODULE_OTHER");Finally, you can also modify the log levels of individual modules.
// Only log messages from the custom APP_MODULE_NETWORK
[NBULog setAppLogLevel:DDLogLevelOff];
[NBULog setAppLogLevel:DDLogLevelInfo
forModule:APP_MODULE_NETWORK];
[NBULog setKitLogLevel:DDLogLevelWarning
forModule:NBUKIT_MODULE_ADDITIONS]; // When using NBUKit
XcodeColors
When installed, XcodeColors are automatically enabled for the Xcode console.
On-Device Log Console and GUI to Ajust Levels
When LumberjackConsole is present you can add am on-device dashboard logger and adjust log levels from the UI.
#ifndef MY_PRODUCTION_MACRO
// Register custom modules before adding the dashboard
[NBULog registerAppContextWithModulesAndNames:@{@(APP_MODULE_NETWORK) : @"Network",
@(APP_MODULE_OTHER) : @"Other"}];
// Add dashboard only for testing builds
[NBULog addDashboardLogger];
#endifInstallation
Add pod 'NBULog' to your CocoaPods' Podfile:
platform :ios, '8.0'
use_frameworks!
pod 'NBULog'
# Optional on-device console
pod 'NBULog/Console'Documentation

Usage in 3rd Party Libraries
You can easily use NBULog in your library when available without making NBULog a requirement.
1. Conditionally Use NBULog
...and fallback to CocoaLumberjack or NSLog otherwise.
E.g. from NBUKit's NBUKitPrivate.h:
// NBUKitPrivate.h
// ...
// a) Use NBULog for logging when available
#if __has_include("NBULog.h")
#import "NBULog+NBUKit.h"
#undef LOG_CONTEXT
#define LOG_CONTEXT NBUKIT_LOG_CONTEXT
#undef LOG_MODULE
#define LOG_MODULE NBUKIT_MODULE_DEFAULT
#undef LOG_LEVEL
#define LOG_LEVEL [NBULog kitLogLevel]
// b) Else try CocoaLumberjack
#elif __has_include("DDLog.h")
#ifdef DEBUG
#define NBUKitLogLevel DDLogLevelVerbose
#else
#define NBUKitLogLevel DDLogLevelWarning
#endif
#define LOG_LEVEL_DEF NBUKitLogLevel
#import <CocoaLumberjack/DDLog.h>
#define NBULogError(frmt, ...) DDLogError(frmt, ##__VA_ARGS__)
#define NBULogWarn(frmt, ...) DDLogWarn(frmt, ##__VA_ARGS__)
#define NBULogInfo(frmt, ...) DDLogInfo(frmt, ##__VA_ARGS__)
#define NBULogDebug(frmt, ...) DDLogDebug(frmt, ##__VA_ARGS__)
#define NBULogVerbose(frmt, ...) DDLogVerbose(frmt, ##__VA_ARGS__)
#define NBULogTrace() NBULogDebug(@"%@", THIS_METHOD)
// c) Else fallback to NSLog
#else
#ifdef DEBUG
#define LOG_LEVEL 3
#else
#define LOG_LEVEL 2
#endif
#define THIS_METHOD NSStringFromSelector(_cmd)
#define NBULogError(frmt, ...) do{ if(LOG_LEVEL >= 1) NSLog((frmt), ##__VA_ARGS__); } while(0)
#define NBULogWarn(frmt, ...) do{ if(LOG_LEVEL >= 2) NSLog((frmt), ##__VA_ARGS__); } while(0)
#define NBULogInfo(frmt, ...) do{ if(LOG_LEVEL >= 3) NSLog((frmt), ##__VA_ARGS__); } while(0)
#define NBULogDebug(frmt, ...) do{ if(LOG_LEVEL >= 4) NSLog((frmt), ##__VA_ARGS__); } while(0)
#define NBULogVerbose(frmt, ...) do{ if(LOG_LEVEL >= 5) NSLog((frmt), ##__VA_ARGS__); } while(0)
#define NBULogTrace() NBULogDebug(@"%@", THIS_METHOD)
#endif2. Register a Log Context and Optional Modules
// NBULog+NBUKit.h
#if __has_include("NBULog.h")
#import <NBULog/NBULog.h>
// NBUKit log context
#define NBUKIT_LOG_CONTEXT 110
// NBUKit modules
#define NBUKIT_MODULE_DEFAULT 0
@interface NBULog (NBUKit)
// Allow to set and read the current levels.
+ (DDLogLevel)kitLogLevel;
+ (void)setKitLogLevel:(DDLogLevel)logLevel;
@end
#endifThen register your context and modules if you want them to appear in LumberjackConsole.
// NBULog+NBUKit.m
#if __has_include("NBULog.h")
#import "NBULog+NBUKit.h"
#import <NBULog/NBULogContextDescription.h>
@implementation NBULog (NBUKit)
+ (void)load
{
// Register the NBUKit log context
[NBULog registerContextDescription:[NBULogContextDescription descriptionWithName:@"NBUKit"
context:NBUKIT_LOG_CONTEXT
modulesAndNames:nil
contextLevelBlock:^{ return [NBULog kitLogLevel]; }
setContextLevelBlock:^(int level) { [NBULog setKitLogLevel:level]; }
contextLevelForModuleBlock:NULL
setContextLevelForModuleBlock:NULL]];
}
+ (DDLogLevel)kitLogLevel
{
// ...
}
+ (void)setKitLogLevel:(DDLogLevel)logLevel
{
// ...
}
@end
#endif
