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 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!

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，會生成一個 deb 包，deb 安裝到手機上面，有多種方式：
通過 iFile 進行安裝：使用 iTools 等工具將這個 deb 包拷貝到手機中，利用 iFile 瀏覽進行安裝；
ssh-copy-id 指定認證文件$ 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 有兩個不同的版本，最新版本不支持 lzma：
$ make package
> Making all for tweak testTweakDemo…
==> Preprocessing Tweak.xm…
==> Compiling Tweak.xm(armv7)…
==> Linking tweak testTweakDemo(armv7)…
clang: warning: libstdc++ is deprecated; move to libc++ with a minimum deployment target of iOS 7[-Wdeprecated]==> Preprocessing Tweak.xm…
==> Compiling Tweak.xm(arm64)…
==> Linking tweak testTweakDemo(arm64)…
clang: warning: libstdc++ is deprecated; move to libc++ with a minimum deployment target of iOS 7[-Wdeprecated]==> Merging tweak testTweakDemo…

> Making stage for tweak testTweakDemo…
dpkg-deb: error: obsolete compression type 'lzma'; use xz insteadType dpkg-deb --help for help about manipulating *.deb files;

make:***[internal-package] Error 2
Debian 'dpkg' package management program version 1.18.24(darwin-amd64)
brew switch dpkg 1.18.10
brew link dpkg
brew pin dpkg 1.18.10
驗證是否修復(fù)：
$ make package
> Making all for tweak testTweakDemo…
make[2]: Nothing to be done for `internal-library-compile'.> Making stage for tweak testTweakDemo…
dpkg-deb: building package 'com.yourcompany.testtweakdemo'in'./packages/com.yourcompany.testtweakdemo_0.0.1-2+debug_iphoneos-arm.deb'.
另如果只修改為 XZ 的話，屆時安裝的時候仍會報錯：

② THEOS_DEVICE_IP 設(shè)置錯誤
