A fast and simple yet powerful and flexible logging framework for Mac and iOS. CocoaLumberjack is really easy to use as it's DDLog macros use the exact same syntax as NSLog, but is an order of magnitude faster and offers many more powerful features. You can configure it send log statements to multiple loggers such as a file, the console, or a custom logger to send your log statements to a database or over the network. It's also extremely configurable with options to change log levels per file, logger or Xcode configuration and also to compress archived log files and upload log files to a central server.
