由于最近在换工作，好久没空来学习了，今天大号环境，写一个helloworld 来测试一下，没想到问题还挺多的。
首先按照iOS应用逆向工程 中的helloworld 示例写好后，编译：
$ make package install
Making all for tweak iOSREGreetings…
==> Preprocessing Tweak.xm…
Tweak.xm:5: error: %orig does not make sense outside a function
make[3]: *** [/Users/uusafe/iosre/iosregreetings/.theos/obj/debug/armv7/Tweak.xm.51c367f0.o] Error 22
make[2]: *** [/Users/uusafe/iosre/iosregreetings/.theos/obj/debug/armv7/iOSREGreetings.dylib] Error 2
make[1]: *** [internal-library-all_] Error 2
make: *** [iOSREGreetings.all.tweak.variables] Error 2
uusafedeiMac:iosregreetings uusafe$ vim Tweak.xm
由于我使用vi编辑器的写的，所以，我就返回去仔细查看了Tweak.xm
$ vim Tweak.xm
(⊙o⊙)…
发现由于我的大意，忘了%hook SpringBoard
写好后，再编译
$ make package install
Making all for tweak iOSREGreetings…
==> Preprocessing Tweak.xm…
==> Compiling Tweak.xm (armv7)…

很明确，找不到NullabilityCompat.h
还好，有我们的Google 大神
将这个头文件的下载下来
将里面的文件copy到/opt/theos/include 中
$ sudo cp -R /Users/uusafe/Downloads/headers-master/* /opt/theos/include/
再编译，
$ make package install
