1、在XCode中新建静态库工程:DDLogLib。
2、添加对外暴露接口的头文件DDLogLibHeader.h
3、命令行进入DDLogLib目录，运行pod init，并修改Podfile
4、运行pod install，并打开DDLogLib.xcworkspace。
5、运行pod spec create DDLogLib，创建DDLogLib.podspec文件，并编辑。
# Be sure to run `pod spec lint DDLogLib.podspec‘ to ensure this is a
# valid spec and to remove all comments including this before submitting the spec.
#
# To learn more about Podspec attributes see http://docs.cocoapods.org/specification.html
# To see working Podspecs in the CocoaPods repo see https://github.com/CocoaPods/Specs/
#
Pod::Spec.new do |s|
# ――― Spec Metadata ―――――――――――――――――――――――――――――――――――――――――――――――――――――――――― #
#
# These will help people to find your library, and whilst it
# can feel like a chore to fill in it‘s definitely to your advantage. The
# summary should be tweet-length, and the description more in depth.
#
s.name = "DDLogLib"
s.version = "0.0.1"
s.summary = "A short description of DDLogLib."
s.description = <<-DESC
A longer description of DDLogLib in Markdown format.
* Think: Why did you write this? What is the focus? What does it do?
* CocoaPods will be using this to generate tags, and improve search results.
* Try to keep it short, snappy and to the point.
* Finally, don‘t worry about the indent, CocoaPods strips it!
DESC
s.homepage = "http://EXAMPLE/DDLogLib"
# s.screenshots = "www.example.com/screenshots_1.gif", "www.example.com/screenshots_2.gif"
# ――― Spec License ――――――――――――――――――――――――――――――――――――――――――――――――――――――――――― #
#
# Licensing your code is important. See http://choosealicense.com for more info.
# CocoaPods will detect a license file if there is a named LICENSE*
# Popular ones are ‘MIT‘, ‘BSD‘ and ‘Apache License, Version 2.0‘.
#
s.license = "MIT (example)"
# s.license = { :type => "MIT", :file => "FILE_LICENSE" }
# ――― Author Metadata ――――――――――――――――――――――――――――――――――――――――――――――――――――――――― #
#
# Specify the authors of the library, with email addresses. Email addresses
# of the authors are extracted from the SCM log. E.g. $ git log. CocoaPods also
# accepts just a name if you‘d rather not provide an email address.
#
# Specify a social_media_url where others can refer to, for example a twitter
# profile URL.
#
s.author = { "hu5675" => "[email protected]" }
# Or just: s.author = "hu5675"
# s.authors = { "hu5675" => "[email protected]" }
# s.social_media_url = "http://twitter.com/hu5675"
# ――― Platform Specifics ――――――――――――――――――――――――――――――――――――――――――――――――――――――― #
#
# If this Pod runs only on iOS or OS X, then specify the platform and
# the deployment target. You can optionally include the target after the platform.
#
# s.platform = :ios
# s.platform = :ios, "5.0"
# When using multiple platforms
# s.ios.deployment_target = "5.0"
# s.osx.deployment_target = "10.7"
# s.watchos.deployment_target = "2.0"
# ――― Source Location ―――――――――――――――――――――――――――――――――――――――――――――――――――――――――― #
#
# Specify the location from where the source should be retrieved.
# Supports git, hg, bzr, svn and HTTP.
#
s.source = { :git => "http://EXAMPLE/DDLogLib.git", :tag => "0.0.1" }
# ――― Source Code ―――――――――――――――――――――――――――――――――――――――――――――――――――――――――――――― #
#
# CocoaPods is smart about how it includes source code. For source files
# giving a folder will include any swift, h, m, mm, c & cpp files.
# For header files it will include any header in the folder.
# Not including the public_header_files will make all headers public.
#
s.source_files = "DDLogLib", "DDLogLib/**/*.{h,m}"
s.exclude_files = "DDLogLib/Exclude"
s.public_header_files = "DDLogLib/**/*.h"
# ――― Resources ―――――――――――――――――――――――――――――――――――――――――――――――――――――――――――――――― #
#
# A list of resources included with the Pod. These are copied into the
# target bundle with a build phase script. Anything else will be cleaned.
# You can preserve files from being cleaned, please don‘t preserve
# non-essential files like tests, examples and documentation.
#
# s.resource = "icon.png"
s.resources = "DDLogLib/Resources/*.png"
# s.preserve_paths = "FilesToSave", "MoreFilesToSave"
# ――― Project Linking ―――――――――――――――――――――――――――――――――――――――――――――――――――――――――― #
#
# Link your library with frameworks, or libraries. Libraries do not include
# the lib prefix of their name.
#
s.framework = "SystemConfiguration"
# s.frameworks = "SomeFramework", "AnotherFramework"
# s.library = "iconv"
# s.libraries = "iconv", "xml2"
# ――― Project Settings ――――――――――――――――――――――――――――――――――――――――――――――――――――――――― #
#
# If your library depends on compiler flags you can set them in the xcconfig hash
# where they will only apply to your library. If you depend on other Podspecs
# you can include multiple dependencies to ensure it works.
# s.requires_arc = true
# s.xcconfig = { "HEADER_SEARCH_PATHS" => "$(SDKROOT)/usr/include/libxml2" }
s.dependency "CocoaLumberjack"
#s.dependency "other lib"
6、新建工程DDLogLibAPP,与DDLogLib保持在同一目录，命令行进入DDLogLibAPP，运行pod init，并编辑。
# Uncomment this line to define a global platform for your project
# platform :ios, ‘6.0‘
target ‘DDLogLibAPP‘ do
pod ‘DDLogLib‘, :path => ‘../DDLogLib‘
end
target ‘DDLogLibAPPTests‘ do
end
target ‘DDLogLibAPPUITests‘ do
end
7、运行pod install，并打开DDLogLibAPP.xcworkspace编译。
8、在DDLogLib实现printABC方法。
DDLogLib.m
#import "DDLogLib.h"
#import "DDLog.h"
#import "DDFileLogger.h"
#import "DDTTYLogger.h"
static int ddLogLevel = LOG_LEVEL_INFO;
@implementation DDLogLib
- (void)printABC{
NSLog(@"ABC");
DDLogFileManagerDefault *logFileManager = [[DDLogFileManagerDefault alloc] init];
DDFileLogger* _fileLogger = [[DDFileLogger alloc] initWithLogFileManager:logFileManager];
_fileLogger.rollingFrequency = 60 * 60 * 24; // 24 hour rolling
_fileLogger.logFileManager.maximumNumberOfLogFiles = 7; // a weeks worth
//#ifdef DEBUG
[DDLog addLogger:[DDTTYLogger sharedInstance]];// this is log to xcode window.
//#else
[DDLog addLogger:_fileLogger];
//#endif
DDLogInfo(@"DDLog ABC");
}
@end
DDLogLib.h
#import <Foundation/Foundation.h>
@interface DDLogLib : NSObject
- (void)printABC;
@end
9、在DDLogLibAPP中调用。
#import "AppDelegate.h"
#import <DDLogLib/DDLogLib.h>
@interface AppDelegate ()
@end
@implementation AppDelegate
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
// Override point for customization after application launch.
DDLogLib* logLib = [[DDLogLib alloc] init];
[logLib printABC];
return YES;
}
10、运行DDLogLibAPP，一切正常。
11、在DDLogLibAPP中直接使用DDLog。
#import "AppDelegate.h"
#import <DDLogLib/DDLogLib.h>
#import <DDLog.h>
#import <DDFileLogger.h>
#import <DDTTYLogger.h>
static int ddLogLevel = LOG_LEVEL_INFO;
@interface AppDelegate ()
@end
@implementation AppDelegate
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
// Override point for customization after application launch.
//app 通过静态库调用
// DDLogLib* logLib = [[DDLogLib alloc] init];
// [logLib printABC];
//app 直接调用
DDLogFileManagerDefault *logFileManager = [[DDLogFileManagerDefault alloc] init];
DDFileLogger* _fileLogger = [[DDFileLogger alloc] initWithLogFileManager:logFileManager];
_fileLogger.rollingFrequency = 60 * 60 * 24; // 24 hour rolling
_fileLogger.logFileManager.maximumNumberOfLogFiles = 7; // a weeks worth
//#ifdef DEBUG
[DDLog addLogger:[DDTTYLogger sharedInstance]];// this is log to xcode window.
//#else
[DDLog addLogger:_fileLogger];
//#endif
DDLogInfo(@"application ABC");
return YES;
}
12、运行正常打印。
