CocoaLumberjack

CocoaLumberjack is a fast & simple, yet powerful & flexible logging framework for Mac and iOS.
CocoaLumberjack 是一個快速&簡單，是 Mac 和 iOS 上強大&靈活的日志框架.

How to get started

怎么開始

• install via CocoaPods
• 通過 CocoaPods 安裝

Swift version via CocoaPods

通過 CocoaPods 安裝 Swift 版本

platform :ios, '8.0'
pod 'CocoaLumberjack/Swift'
use_frameworks!

Note: Swift is a subspec which will include all the Obj-C code plus the Swift one, so this is sufficient.
For more details about how to use Swift with Lumberjack, see this conversation.

Swift Usage

If you installed using CocoaPods or manually:

import CocoaLumberjack

DDLog.addLogger(DDTTYLogger.sharedInstance()) // TTY = Xcode console
DDLog.addLogger(DDASLLogger.sharedInstance()) // ASL = Apple System Logs

let fileLogger: DDFileLogger = DDFileLogger() // File Logger
fileLogger.rollingFrequency = 60*60*24  // 24 hours
fileLogger.logFileManager.maximumNumberOfLogFiles = 7
DDLog.addLogger(fileLogger)

...

DDLogVerbose("Verbose");
DDLogDebug("Debug");
DDLogInfo("Info");
DDLogWarn("Warn");
DDLogError("Error");

Obj-C version via CocoaPods

通過 CocoaPods 安裝 Obj-C 版本

platform :ios, '7.0'
pod 'CocoaLumberjack'

Obj-C usage

Obj-C 用法

If you're using Lumberjack as a framework, you can @import CocoaLumberjack.
如果你在使用 Lumberjack 作為框架，你可以@import CocoaLumberjack.

Otherwise, #import <CocoaLumberjack/CocoaLumberjack.h>
否則，#import <CocoaLumberjack/CocoaLumberjack.h>

[DDLog addLogger:[DDTTYLogger sharedInstance]]; // TTY = Xcode console
// TTY = Xcode 控制臺
[DDLog addLogger:[DDASLLogger sharedInstance]]; // ASL = Apple System Logs
// ASL = 蘋果系統日志

DDFileLogger *fileLogger = [[DDFileLogger alloc] init]; // File Logger
fileLogger.rollingFrequency = 60 * 60 * 24; // 24 hour rolling
fileLogger.logFileManager.maximumNumberOfLogFiles = 7;
[DDLog addLogger:fileLogger];

...

DDLogVerbose(@"Verbose");
DDLogDebug(@"Debug");
DDLogInfo(@"Info");
DDLogWarn(@"Warn");
DDLogError(@"Error");

Installation with Carthage (iOS 8+)

Carthage 的安裝方式 （iOS 8+）

Carthage is a lightweight dependency manager for Swift and Objective-C. It leverages CocoaTouch modules and is less invasive than CocoaPods.
Carthage是一個輕量級的 Swift 和 Objective-C 的依賴管理器。它會對 CocoaTouch 模塊起作用，比 CocoaPods 影響的東西要少。

To install with Carthage, follow the instruction on Carthage
按照這個指示安裝Carthage
Cartfile

github "CocoaLumberjack/CocoaLumberjack"

• or install manually
• read the Getting started guide, check out the FAQ section or the other docs
• if you find issues or want to suggest improvements, create an issue or a pull request
• for all kinds of questions involving CocoaLumberjack, use the Google group or StackOverflow (use #lumberjack).

CocoaLumberjack 2

Migrating to 2.x

遷移至 2.x 版本

• Replace DDLog.h imports by #import <CocoaLumberjack/CocoaLumberjack.h>.
• 導入用#import <CocoaLumberjack/CocoaLumberjack.h>替換 DDLog.h .

Advanced users, third party libraries:

• Replace all DDLogC macros for regular DDLog macros.
• Replace log level (LOG_LEVEL_*) macros with DDLogLevel enum values
• Replace log flag (LOG_FLAG_*) macros with DDLogFlag enum values
• Replace DDLogMessage ivars and method calls to the new ivars and methods
  • logMsg with _message
  • logLevel with _level
  • logFlag with _flag
  • logContext with _context
  • lineNumber with _line (type changed from int to NSUInteger)
  • file with _file (filename contains just the file name, without the extension and the full path)
  • timestamp with _timestamp
  • methodName with function
• Replace DDAbstractLogger formatter to logFormatter
• YSSingleFileLogger ivars are no longer accesible, use the methods instead
• Replace [DDLog addLogger:withLogLevel:] with [DDLog addLogger:withLevel:]

Forcing 1.x

If an included library requires it, you can force CocoaLumberjack 1.x by setting the version before the conflicting library:

pod 'CocoaLumberjack', '~> 1.9'
pod 'ConflictingLibrary'

Features

特色

Lumberjack is Fast & Simple, yet Powerful & Flexible.

It is similar in concept to other popular logging frameworks such as log4j, yet is designed specifically for Objective-C, and takes advantage of features such as multi-threading, grand central dispatch (if available), lockless atomic operations, and the dynamic nature of the Objective-C runtime.
它和其他像 log4j 這樣的熱門日志記錄框架的概念相似，目前只特別針對 Objective-C,在多線程，grand central dispatch（GCD），無鎖的原子性操作比較有優勢，還有Objective-C 運行時的動態特色。

Lumberjack is Fast

In most cases it is an order of magnitude faster than NSLog.
在大多數情況下，它比 NSLog 快速、有條理。

Lumberjack is Simple

It takes as little as a single line of code to configure lumberjack when your application launches. Then simply replace your NSLog statements with DDLog statements and that's about it. (And the DDLog macros have the exact same format and syntax as NSLog, so it's super easy.)
配置lumberjack 只需要很少的幾行代碼。只需簡單的用DDLog替換 NSLog 。（并且DDLog的宏和NSLog的格式語法完全相同，所以它超級簡單）

Lumberjack is Powerful:

One log statement can be sent to multiple loggers, meaning you can log to a file and the console simultaneously. Want more? Create your own loggers (it's easy) and send your log statements over the network. Or to a database or distributed file system. The sky is the limit.
一個日志聲明可以被多次發送，意味著你可以同時輸出日志到控制臺和文件。想要更多？創建你自己的日志器，并且通過網絡發送日志，或者發送到數據庫、文件分發系統。完全沒有限制。

Lumberjack is Flexible:

Configure your logging however you want. Change log levels per file (perfect for debugging). Change log levels per logger (verbose console, but concise log file). Change log levels per xcode configuration (verbose debug, but concise release). Have your log statements compiled out of the release build. Customize the number of log levels for your application. Add your own fine-grained logging. Dynamically change log levels during runtime. Choose how & when you want your log files to be rolled. Upload your log files to a central server. Compress archived log files to save disk space...

This framework is for you if:
