① control 文件
control 文件存儲(chǔ)項(xiàng)目有關(guān)的信息：名稱、版本、開發(fā)者：
IMP MSHookMessage(Class class, SEL selector, IMP replacement,constchar* prefix);// prefix should be NULL.voidMSHookMessageEx(Class class, SEL selector, IMP replacement, IMP *result);voidMSHookFunction(void* function,void* replacement,void** p_original);
Tweak.xm 的文件名后綴 x 代表的含義：
Tweak.xm 的文件名后綴 x 代表支持 Logos 語法， 如果只有一個(gè) x 代表源文件支持 Logos 和 C 語法；如果是 xm，說明源文件支持 Logos 和 C/C++ 語法；
其中的 %hook,%orig,%log 等都是 Logos 語法支持的內(nèi)容。
$ more Tweak.xm
/* How to Hook with Logos
Hooks are written with syntax similar to that of an Objective-C @implementation.
You don't need to #include <substrate.h>, 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

⑤ 編譯和安裝deb
使用命令 make package 編譯，其中 packages 文件夾下保留的是每一次編譯成功產(chǎn)生的 deb 安裝包文件。theos 編譯之后，會(huì)生成一個(gè) deb 包，deb 安裝到手機(jī)上面，有多種方式：
通過 iFile 進(jìn)行安裝：使用 iTools 等工具將這個(gè) deb 包拷貝到手機(jī)中，利用 iFile 瀏覽進(jìn)行安裝；
ssh-copy-id 指定認(rèn)證文件$ ssh-copy-id -i id_rsa_Theos125 root@192.168.2.131
$ ssh-copy-id root@192.168.2.212/usr/bin/ssh-copy-id: INFO: Source of key(s) to be installed:"/Users/devzkn/.ssh/id_rsa_Theos.pub"/usr/bin/ssh-copy-id: INFO: attempting to log in with the new key(s), to filter out any that are already installed
/usr/bin/ssh-copy-id: INFO:1key(s) remain to be installed --if you are prompted now it is to install the new keys
root@192.168.2.212's password: Number of key(s) added:1Now try logging into the machine, with:"ssh 'root@192.168.2.212'"
and check to make sure that only the key(s) you wanted were added.
三、常見問題
① 壓縮方式不被支持
原因是 dpkg 有兩個(gè)不同的版本，最新版本不支持 lzma：

==> Linking tweak testTweakDemo(armv7)…
