tweak 工程目录结构介绍
- Makefile
默认文件信息： // 工程包含的通用头文件 include $(THEOS)/makefiles/common.mk // 创建工程时指定的“Project Name，指定好之后一般不要再更改 TWEAK_NAME = MyFirstReProject // tweak包含的源文件，指定多个文件时用空格隔开 MyFirstReProject_FILES = Tweak.xm // tweak工程的头文件，一般有application.mk、tweak.mk和tool.mk几类 include $(THEOS_MAKE_PATH)/tweak.mk // 指定tweak安装之后，需要做的事情，这里是杀掉SpringBoard进程 after-install:: install.exec "killall -9 SpringBoard" 补充： // 编译debug或者release DEBUG = 0 // 越狱iPhone的ip地址 THEOS_DEVICE_IP = 192.168.1.113 // 指定支持的处理器架构 ARCHS = armv7 arm64 // 指定需要的SDK版本iphone:Base SDK:Deployment Target TARGET = iphone:latest:8.0 //最新的SDK，程序发布在iOS8.0以上 // 导入框架，多个框架时用空格隔开 MyFirstReProject_FRAMEWORKS = UIKit MyFirstReProject_PRIVATE_FRAMEWORKS = AppSupport // 链接libsqlite3.0.dylib、libz.dylib和dylib1.o MyFirstReProject_LDFLAGS = -lz –lsqlite3.0 –dylib1.o // make clean clean:: rm -rf ./packages/*-
tweak文件
- xm中的x代表这个文件支持logos语法，如果后缀名单独是一个x说明源文件支持logos和c语法；如果后缀名是xm，说明源文件支持logos和c/c++语法。
- %hook指定需要hook的class，必须以%end结尾
- %log该指令在%hook内部是使用，将函数名的类名、参数等信息写入syslog，Cydia内搜索安装syslog
- %orig该指令在%hook内部使用，执行被钩住（hook）的函数的原始代码。
- tewak工程创建的代码
/* How to Hook with Logos Hooks are written with syntax similar to that of an Objective-C @implementation. You don't need to #include, it will be done automatically, as will the generation of a class list and an automatic constructor. %hook ClassName // Hooking a class method + (id)sharedInstance { return %orig; } // Hooking an instance method with an argument. - (void)messageName:(int)argument { %log; // Write a message about this call, including its class, name and arguments, to the system log. %orig; // Call through to the original function with its original arguments. %orig(nil); // Call through to the original function with a custom argument. // If you use %orig(), you MUST supply all arguments (except for self and _cmd, the automatically generated ones.) } // Hooking an instance method with no arguments. - (id)noArguments { %log; id awesome = %orig; [awesome doSomethingElse]; return awesome; } // Always make sure you clean up after yourself; Not doing so could have grave consequences! %end */ - 修改tewak工程的xm文件之后的代码，hook Springboard当按下home键触发的函数，并打印信息
%hook SpringBoard - (void)_menuButtonDown:(id)arg1 { NSLog(@"x=%d, y=%d", 10, 20); %log((NSString *)@"iOSRE", (NSString *)@"Debug"); %orig; // call the original _menuButtonDown: } %end -

Deb包介绍 官网
- deb包本质是一个压缩包文件，里面包含一些特定的目录和文件。安装过程就是dpkg程序按照指定的规则去拷贝和执行脚本。
# 安装deb包 dpkg -i filename # 查看目录结构 ➜ packages dpkg -c com.iosre.myfirstrepoject_0.0.1-10+debug_iphoneos-arm.deb drwxr-xr-x root/wheel 0 2018-04-25 13:45 . drwxr-xr-x root/wheel 0 2018-04-25 13:45 ./Library drwxr-xr-x root/wheel 0 2018-04-25 13:45 ./Library/MobileSubstrate drwxr-xr-x root/wheel 0 2018-04-25 13:45 ./Library/MobileSubstrate/DynamicLibraries -rw-r--r-- root/wheel 57 2018-04-25 13:45 ./Library/MobileSubstrate/DynamicLibraries/MyFirstRePoject.plist -rwxr-xr-x root/wheel 132896 2018-04-25 13:45 ./Library/MobileSubstrate/DynamicLibraries/MyFirstRePoject.dylib- DEBIAN目录-存放control文件、及安装和卸载时需要执行的文件等
- control文件

-
preinst
- 在Deb包文件解包之前，将会运行该脚本。许多“preinst”脚本的任务是停止作用于待升级软件包的服务，直到软件包安装或升级完成。
-
postinst
- 该脚本的主要任务是完成安装包时的配置工作。许多“postinst”脚本负责执行有关命令为新安装或升级的软件重启服务。
-
prerm
- 该脚本负责停止与软件包相关联的daemon服务。它在删除软件包关联文件之前执行。
-
postrm
- 该脚本负责修改软件包链接或文件关联，或删除由它创建的文件。

常见的Logos语法 维基百科wiki
- block-level
- %hook 制定需要hook的Class，必须以%end结尾。可以被多个%group包含
%hook SBApplicationController - (void)uninstallApplication:(SBApplication *)application { NSLog(@"Hey, we're hooking uninstallApplication:!"); %orig; // Call the original implementation of this method return; } %end- %group 该指令用于将%hook分组，便于代码管理及按条件初始化分组，必须以%end结尾。一个％group可以包含多个%hook,所有不属于某个自定义group的％hook会被隐式归类到％group_ungrouped中。
%group iOS8 %hook IOS8_SPECIFIC_CLASS // your code here %end // end hook %end // end group ios8 %group iOS9 %hook IOS9_SPECIFIC_CLASS // your code here %end // end hook %end // end group ios9 %ctor { if (kCFCoreFoundationVersionNumber > 1200) { %init(iOS9); } else { %init(iOS8); } }- %new 通过在方法定义之上添加这个指令，将一个新方法添加到钩子类或子类中。签名是新方法的Objective-C类型编码;如果省略，将生成一个。必须在%hook块内。
// 使用 // %new
// %new(signature)
%hook SBApplicationController
- (void)uninstallApplication:(SBApplication *)application {
NSLog(@"Hey, we're hooking uninstallApplication:!");
%orig; // Call the original implementation of this method
return;
}
%new
- (void)namespaceNewMethod {
NSLog(@"We've added a new method to SpringBoard.");
}
%end
```
* Top level
* %ctor tweak的构造函数,完成初始化工作；如果不显示定义，Theos会自动生成一个%ctor,并在其中调用%init(_ungrouped)。
* %dtor tweak的构造函数,完成收尾。如果不显示定义，Theos会自动生成一个%dtor。
* Function level
* %init 该指令用于初始化某个％group，必须在%hook或％ctor内调用；如果带参数，则初始化指定的group，如果不带参数，则初始化_ungrouped。注： 切记，只有调用了％ini,对应的%group才能起作用！
```
%ctor {
if (kCFCoreFoundationVersionNumber > 1200) %init(iOS9);
else %init(iOS8);
}
```
* %c 该指令的作用等同于objc_getClass或NSClassFromString,即动态获取一个类的定义，在%hook或％ctor内使用 。
```
%hook SpringBoard
- (void)_menuButtonDown:(id)down
{
%orig;
SBScreenShotter *shotter = [%c(SBScreenShotter) sharedInstance];
[shotter saveScreenshot:YES];
}
%end@
```
* %log 该指令在%hook内部使用，将函数的类名、参数等信息写入syslog,可以％log([(),…..])的格式追加其他打印信息。
* %orig 该指令在%hook内部使用，执行被hook的函数的原始代码；也可以用％orig更改原始函数的参数。

使用Logos语法，点击home建截屏，%new新添加实例方法和类方法
