ios objc 方法调用记录插件：itracer v1.1
如果你想逆向 某些app的调用流程 或者 系统app的一些功能的 私有 framework class api 调用流程， 可以试试此工具
只需要 配置需要挂接的 类名和app名， 就可以实时追踪 相关功能的 调用流程。 支持批量 hook n多个类名
更新内容：
1. 增强程序稳定性， 但是偶尔trace某些method的参数信息还是会挂（比以前好多了 = =）
2. 增加对ios 系统服务进程的支持， 不再依赖mobilesubstrate插件，采用直接注入方式进行hook
3. 可配置需要挂接的class， 配置文件以xml格式描述
4. mac 上 x86/x64 支持（x64上暂时还不稳定，所以mac上版本暂时先不透露了。）
5. 挂接过程中无需重启springboard， 更加方便
1.配置需要挂接的class
修改itrace.xml配置文件，增加需要hook的类名：
<?xml version="1.0" encoding="utf-8"?>
<itrace>
<class>
<SSDevice/>
<SSDownload/>
<SSDownloadManager/>
<SSDownloadQueue/>
<CPDistributedMessagingCenter/>
<CPDistributedNotificationCenter/>
<NSString args="0"/>
</class>
</itrace>
注： 尽量不要去hook， 频繁调用的class， 比如 UIView NSString， 否则会很卡，操作就不方便了。
注： 如果挂接某个class， 中途打印参数信息挂了， 可以在对应的类名后面 加上 args="0" 属性， 来禁止打印参数信息， 这样会稳定点。
如果要让所有类都不打印参数信息， 可以直接设置： <class args="0">
2.安装文件
将整个itracer目录下的所有文件用手机助手工具，上传到ios系统上的 /tmp 下面：
/tmp/itracer
/tmp/itrace.dylib
/tmp/itrace.xml
3. 进行trace
进入itracer所在目录： cd /tmp
修改执行权限： chmod 777 ./itracer
运行程序: ./itracer springboard (spingboard 为需要挂接的进程名， 支持简单的模糊匹配)
4. 查看 trace log， 注： log 的实际输出在： Xcode-Windows菜单-Organizer-Console 中：

后记：
由于最近空闲时间少，这个工具暂时就先弄到这了， 后续有时间在加上 native funtion 的 支持和 参数配置功能。
