工程文件结构
Makefile
//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

//链接libsqlite3.0.dylib、libz.dylib和dylib1.o

//make clean

tweak文件
“xm”中的“x”代表这个文件支持Logos语法，如果后缀名是单独一个“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。
/* 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
*/
参数说明
- %hook 指定需要hook的class，必须以%end结尾
- %log 该指令在%hook内部使用，将函数的类名、参数等信息写入syslog
Cydia内搜索安装syslogd
- %orig该指令在%hook内部使用，执行被钩住（hook）的函数的原始代码。
control
control文件记录了deb包管理系统所需的基本信息，会被打包进deb包里。
