class-dump

==========



class-dump is a command-line utility for examining the Objective-C

segment of Mach-O files.  It generates declarations for the classes,

categories and protocols.  This is the same information provided by

using 'otool -ov', but presented as normal Objective-C declarations.



The latest version and information is available at:



    http://stevenygard.com/projects/class-dump



The source code is also available from my Github repository at:

Usage

-----



    class-dump 3.5 (64 bit)

    Usage: class-dump [options] 



      where options are:

            -a             show instance variable offsets

            -A             show implementation addresses

            --arch   choose a specific architecture from a universal binary (ppc, ppc64, i386, x86_64)

            -C      only display classes matching regular expression

            -f        find string in method name

            -H             generate header files in current directory, or directory specified with -o

            -I             sort classes, categories, and protocols by inheritance (overrides -s)

            -o        output directory used for -H

            -r             recursively expand frameworks and fixed VM shared libraries

            -s             sort classes and categories by name

            -S             sort methods by name

            -t             suppress header in output, for testing

            --list-arches  list the arches in the file, then exit

            --sdk-ios      specify iOS SDK version (will look in /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS.sdk

            --sdk-mac      specify Mac OS X version (will look in /Developer/SDKs/MacOSX.sdk

            --sdk-root     specify the full SDK root path (or use --sdk-ios/--sdk-mac for a shortcut)



- class-dump AppKit:



    class-dump /System/Library/Frameworks/AppKit.framework



- class-dump UIKit:



    class-dump /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS4.3.sdk/System/Library/Frameworks/UIKit.framework



- class-dump UIKit and all the frameworks it uses:



    class-dump /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS4.3.sdk/System/Library/Frameworks/UIKit.framework -r --sdk-ios 4.3



- class-dump UIKit (and all the frameworks it uses) from developer tools that have been installed in /Dev42 instead of /Developer:



    class-dump /Dev42/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS5.0.sdk/System/Library/Frameworks/UIKit.framework -r --sdk-root /Dev42/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS5.0.sdk
