当滑动列表的时候，控制会打印LCUS为前缀的所有调用，可以看到滑动的过程中究竟调用了哪些方法
When the list is swiped, the control prints all calls that are prefixed by LCUS, and you can see which methods were called during the sliding process.
objective-c行为记录器，跟踪objc_msgSend
Objective-c behavior recorder, tracking objc_msgSend
- 模拟器使用, 勾选hook_objc_msgSend_x86.s参与编译 (Use by the simulator, check hook_objc_msgSend_x86.s to compile)
- 真机使用5s以上机型，勾选hook_objc_msgSend.s参与编译 (Real machine use 5s or more models, check hook_objc_msgSend.s to compile)
- 过滤器LCSFilterBlock中不能再次调用objc_send, 也就是调用oc方法（包括NSLog），会导致无限循环。( The objc_send cannot be called again in the filter LCSFilterBlock, that is, calling the oc method (including NSLog) will result in an infinite loop.)
- 目前此实现目的仅用于调试，不要用于线上代码。( Currently this implementation is only for debugging purposes, not for online code.)
