Introduction

Welcome to the documentation for LogIO-CocoaLumberjack, a powerful and flexible logging framework for iOS applications. This framework allows you to easily log messages of varying levels of importance throughout your app, helping you to debug and analyze your code more efficiently.

Features

  • Multiple log levels: LogIO-CocoaLumberjack supports different log levels (verbose, debug, info, warning, error) to help you filter and prioritize your log messages.
  • Flexible log formatting: You can easily customize the format of your log messages to suit your preferences and needs.
  • Contextual logging: LogIO-CocoaLumberjack allows you to attach context information to your log messages, such as the current view controller or user session, making it easier to track down issues.
  • Asynchronous logging: The framework performs logging operations asynchronously, reducing the impact on your app’s performance.
  • Colorful console output: You can enable colorful console output to make it easier to visually distinguish between different log levels.
  • File logging: LogIO-CocoaLumberjack can also write log messages to files, providing a persistent record of your app’s debug information.
  • Custom logging destinations: You can create custom log destinations to send log messages to external services or plugins.

Installation

  1. Using CocoaPods:
    • Add the following line to your Podfile:
      pod 'LogIO-CocoaLumberjack'
    • Run pod install in the terminal in the same directory as your Podfile.
    • Import the framework in your code using:
      @import LogIO_CocoaLumberjack;
  2. Using Carthage:
    • Add the following line to your Cartfile:
      github "LogIO-CocoaLumberjack"
    • Run carthage update in the terminal in the same directory as your Cartfile.
    • Drag the built framework LogIO-CocoaLumberjack.framework into your Xcode project.
  3. Manual installation:
    • Clone the LogIO-CocoaLumberjack repository to your local machine.
    • Drag the LogIO-CocoaLumberjack.xcodeproj file into your Xcode project.
    • In your target’s settings, go to the “General” tab and add the framework under the “Frameworks, Libraries, and Embedded Content” section.
    • Import the framework in your code using:
      @import LogIO_CocoaLumberjack;

Getting Started

To start using LogIO-CocoaLumberjack, you’ll need to do the following:

  1. Create a logger instance and set its log level based on your requirements.
  2. Configure and add log formatters and log destinations.
  3. Start logging messages using the logger instance.
  4. (Optional) Customize the log formatting and add custom log destinations.

Let’s go through these steps in more detail:

1. Create a Logger

In your app’s setup code, create an instance of the DDLog class to use as the main logger.


DDLog *logger = [DDLog sharedInstance];

2. Set the Log Level

You can set the log level for your logger instance to control which messages are logged. The available log levels, from highest to lowest, are:

  • DDLogFlagError (log only error messages)
  • DDLogFlagWarning (log warning and error messages)
  • DDLogFlagInfo (log info, warning, and error messages)
  • DDLogFlagDebug (log debug, info, warning, and error messages)
  • DDLogFlagVerbose (log all messages)

To set the log level, use the following method:


[logger setLogLevel:DDLogLevelVerbose];

3. Configure and Add Log Formatters

You can customize the format of your log messages by adding log formatters. Log formatters take a log message and format it into a human-readable string.

To add a log formatter, use the following code:


[logger addLogFormatter:[[MyCustomLogFormatter alloc] init]];

Replace MyCustomLogFormatter with the name of your log formatter class.

4. Configure and Add Log Destinations

A log destination determines where your log messages are sent. LogIO-CocoaLumberjack provides built-in log destinations such as the console logger and file logger, but you can also create custom log destinations.

To add a log destination, use the following code:


[logger addLogDestination:[[DDConsoleLogger sharedInstance] init]];

Replace DDConsoleLogger with the name of your desired log destination class.

5. Start Logging

You can now start logging messages using the logger instance. For example:


DDLogVerbose(@"This is a verbose log message");
DDLogDebug(@"This is a debug log message");
DDLogInfo(@"This is an info log message");
DDLogWarn(@"This is a warning log message");
DDLogError(@"This is an error log message");

Replace the log message content as per your requirements.

6. (Optional) Customize Log Formatting

You can customize the log formatting by subclassing the DDAbstractFormatter class and implementing your desired format logic. Refer to the official CocoaLumberjack documentation for more information on creating custom formatters.

7. (Optional) Add Custom Log Destinations

To add custom log destinations, create a new class conforming to the DDLogDestination protocol, and implement the required methods. Follow the official CocoaLumberjack documentation for more details on creating custom log destinations.

That’s it! You now have the basics to start using LogIO-CocoaLumberjack to enhance your logging capabilities in your iOS app.
