class-dump is a command-line utility for examining the Objective-Csegment of Mach-O files. It generates declarations for the classes,categories and protocols. This is the same information provided byusing '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:

class-dump 3.5 (64 bit)Usage: class-dump [options] <mach-o-file>  where options are:        -a             show instance variable offsets        -A             show implementation addresses        --arch <arch>  choose a specific architecture from a universal binary (ppc, ppc64, i386, x86_64)        -C <regex>     only display classes matching regular expression        -f <str>       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 <dir>       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<version>.sdk        --sdk-mac      specify Mac OS X version (will look in /Developer/SDKs/MacOSX<version>.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
