目的:实现生成 private framework 的 .h,以便倒入项目使用私有 api。
一、class-dump
下载地址: http://stevenygard.com/download/
安装步骤:
a) 下载了 dmg 打开并把 class-dump copy 到 /usr/bin/ 目录下;
b) 修改 class-dump 的权限,
$ chmod 777 /usr/bin/class-dump
二、DumpFrameworks.pl
从 github 上别人越狱的工程上下载: https://github.com/shuhongwu/HackSpringDemo/blob/master/DumpFrameworks.pl
a) 放到任意目录可行。
b) 根据自己 framework 的地址,修改路径。
c) cd 到 DumpFrameworks.pl 的路径,并执行
$ ./DumpFrameworks.pl
DumpFrameworks.pl 文件内容:
#!/usr/bin/perl # # 24 November 2008 # Framework Dumping utility; requires class-dump # use strict; use Cwd; use File::Path; my $HOME = (getpwuid($<))[7] || $ENV{'HOME'} or die "Could not find your home directory!"; # This command must be in your path. # http://www.codethecode.com/projects/class-dump/ my $CLASS_DUMP = 'class-dump'; # 这里路径需要小心,后面像别名一样的东东需要换行的 # Public Frameworks dump_frameworks('/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS7.1.sdk/System/Library/Frameworks', 'Frameworks'); # Private Frameworks dump_frameworks('/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS7.1.sdk/System/Library/PrivateFrameworks', 'PrivateFrameworks'); sub dump_frameworks { my($dir, $subdir) = @_; opendir(my $dirh, $dir) or die "Could not opendir($dir) - $!"; # Iterate through each framework found in the directory foreach my $file (grep { /.framework$/ } readdir($dirh)) { # Extract the framework name (my $fname = $file) =~ s/.framework$//; print "Framework: $fname "; my $headers_dir = "$HOME/Headers/$subdir/$fname"; # Create the folder to store the headers mkpath($headers_dir); # Perform the class-dump my $cwd = cwd(); chdir($headers_dir) or die "Could not chdir($headers_dir) - $!"; system($CLASS_DUMP, '-H', "$dir/$file"); if($? == -1) { die "Could not execute $CLASS_DUMP - $! "; } chdir($cwd) or die "Could not chdir($cwd) - $!"; } }
三、使用
$ class-dump -H xxx(打包好的文件) -o xxx.h
四、其他
class-dump 作用的对象必须是未经过加密的可执行文件,而从 app store 下载的 app 都是经过签名加密的。
