iOS9 class dump header

获取系统私有API，网上有很多资料总结了一下就三种方式：

使用class-dump可以提取系统私有API列表

使用class-dump+DumpFrameworks.pl，这个可以一次性提取所有系统Framework与PrivateFrameworks的API列表

直接使用已经提取好的API列表github地址

DumpFrameworks.pl代码如下：

#!/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';

# Public Frameworks  /xcode4/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS4.3.sdk////Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS4.2.sdk/System/Library
# /Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator4.2.sdk/System/Library/Frameworks  /xcode4/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator5.0.sdk/System/Library
dump_frameworks('/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator9.2.sdk/System/Library/Frameworks',
'Frameworks');

# Private Frameworks
dump_frameworks('/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator9.2.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\n";

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 - $!\n";
}
#
#    elsif($? & 127)
#    {
#      printf("$CLASS_DUMP died with signal %d, %s coredump\n",
#             ($? & 127),  ($? & 128) ? 'with' : 'without');
#      exit;
#    }
#
#    elsif(my $ret = $? >> 8)
#    {
#      die "The command '$CLASS_DUMP -H $dir/$file' failed, returning $ret\n";
#    }
#*/
chdir($cwd) or die "Could not chdir($cwd) - $!";
}
}

注意使用DumpFrameworks.pl时要更改系统库的路径为你自己的路径。

但是从class-dump官网下载的最新版本

class-dump-3.5.dmg

却不能获取

iOS9

以后版本的API列表。报错信息：



具体原因

Google

了一下：



原答案地址

然后我从github上获取class-dump开源代码重新编译class-dump的可执行文件，并把这个可执行文件导出重新dump成功获取iOS9以后的系统私有API。具体方法如下：

1.打开class-dump并在TARGETS选中class-dump可执行文件



2.Xcode->Perferences->Locations



3.Advanced->Custom



不要更改任何路径选择后编译该项目。

编译成功后在~Library/Developer/Xcode/DerivedData/Build/Products可以找到这个可执行文件然后用这文件获取系统私有API。
