iOS在Cocoa Touch Static Library使用CocoaPods

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" => "hu5675@126.com" }

# Or just: s.author    = "hu5675"

# s.authors            = { "hu5675" => "hu5675@126.com" }

# 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。
