NGLogger
NGLogger has a minimum log level and passes messages to its appenders
only if this minimum log level is satisfied - otherwise it silently drops
these messages.
NGLogger also offers a factory to instantiate loggers from configs stored
in NSUserDefaults.
NOTE: Except in rare circumstances, do not allocate loggers yourself!
Always try to use the appropriate API of NGLoggerManager if possible.
NGLogger honours the following user default keys:
User Default key Function
----------------------------------------------------------------------------
NGLogDefaultLogLevel The log level to use as a fallback, if no
log level is provided during initialization.
The default is "INFO".
The following keys in the configuration dictionary will be recognized:
Key Function
----------------------------------------------------------------------------
"LogLevel" The log level to use for this logger. If no
log level is provided, sets log level according
to fallback described above.
"Appenders" Array of dictionaries suitable as configuration
provided to NGLogAppender's factory method.
Please see NGLogAppender.h for further
explanation.
LoggerConfig example:
WOHttpTransactionLoggerConfig = {
"LogLevel" = "INFO";
"Appenders" = (
{
"Class" = "NGLogStdoutAppender";
"Formatter" = {
"Class" = "NGLogEventFormatter";
};
},
);
};
