[Tweak]QQ小尾巴插件Tweak代码更新

tree_fly

之前写的一篇帖子和Tweak，由于不能添加自定义小尾巴，没能让诸位装X的更彻底，闲暇时间更新了代码与大家分享。教你修改QQ手机型号为iPhone6Plushttps://www.chinapyg.com/thread-75886-1-1.html



*OS获取设备信息的函数之一 _sysctlbyname()  
苹果官方文档这样写道：
https://developer.apple.com/lega ... sysctlbyname.3.html

The sysctlbyname() function accepts an ASCII representation of the name and internally looks up the
     integer name vector.  Apart from that, it behaves the same as the standard sysctl() function.  For a
     list of ASCII representations of commonly used sysctl names, please see sysctl(1).

     The information is copied into the buffer specified by oldp.  The size of the buffer is given by the
     location specified by oldlenp before the call, and that location gives the amount of data copied after
     a successful call and after a call that returns with the error code ENOMEM.  If the amount of data
     available is greater than the size of the buffer supplied, the call supplies as much data as fits in
     the buffer provided and returns with the error code ENOMEM.  If the old value is not desired, oldp and
     oldlenp should be set to NULL.

     The size of the available data can be determined by calling sysctl() with the NULL argument for oldp.
     The size of the available data will be returned in the location pointed to by oldlenp.
