ddlog-printing information in different colors

1. Installing plugins

Xcodecolors

Github Link: https://github.com/robbiehanson/XcodeColors

Open the Xcodecolors project and compile. It will install Plug and xcodecolors.xcplugin in your computer. Specific path in: ~/library/application Support/developer/shared/xcode/plug-ins/xcodecolors.xcplugin (can take a look).

2. Introduction of third-party libraries

Cocoalumberjack

Github Link: https://github.com/CocoaLumberjack/CocoaLumberjack

3. Modify your printing information to change the NSLog to Ddlog printing, the best new project to use

(ii) Some introductions of Ddlog

Ddlog: Basic class, which must be introduced.

Ddasllogger: Supports writing debug statements to Apple's logs. It is generally being developed for Mac. Optional.

Ddttylogger: Supports writing debug statements to the Xcode console. Even if we want to use it. Optional.

Ddfilelogger: Supports writing debug statements to the file system. Optional.

Ddlog the output level by default provides several of the following:

Ddlogerror: Defining output error text

Ddlogwarn: Define output warning text

Ddloginfo: Defining output Message Text

Ddlogdebug: Defining Output Debug Text

Ddlogverbose: Defining output verbose text

The log levels provided are:

Log_level_error: Only error logs are displayed.

Log_level_warn: including: Log_level_error

Log_level_info: including: Log_level_warn

Log_level_debug: including: Log_level_info

Log_level_verbose: including: Log_level_debug

Log_level_off: Close Log

(iii) partial use of Ddlog

#import "CocoaLumberjack.h"

    static const int Ddloglevel = ddloglevelverbose;//defines the log level    [Ddlog Addlogger:[ddttylogger sharedinstance]];// Initialize the Ddlog log output, where we only want the Xcode console output    [[Ddttylogger sharedinstance] setcolorsenabled:yes];//enable color discrimination    Ddlogerror (@ "error message"); Red    Ddlogwarn (@ "Warning%@", @ "ASD"),//Orange    Ddloginfo (@ "prompt message:%@", @ "quack");//default is black    ddlogverbose (@ "Details error:% D ", 1016); Default is Black

Printing effect:

Tips: If the print color does not change

• Open Product--Edit Scheme
• Select Run-> "Arguments" tab
• Add a new environment Variable named "Xcodecolors" with a value of Yes
• OK, now is the time to witness the miracle, run it once, and you can see.
