在连着线的时候，无论是debug还是release都是正常的，但是当打成IPA后，只能获取总的C++方法个数，无法通过hook获取、统计每个C++方法的执行时间。
iOS13.6

因为pre-main过长，所以想借助hook_cpp_init计算下C++ static initializers的耗时，但结果更加让我迷惑了

initializer time 只需要0.9s，但SumInitTime算出来却是55.47678470611572，请问这是什么情况

`
Total pre-main time: 1.3 seconds (100.0%)
dylib loading time: 197.91 milliseconds (14.4%)
rebase/binding time: 149.23 milliseconds (10.9%)
ObjC setup time: 31.32 milliseconds (2.2%)
initializer time: 988.82 milliseconds (72.3%)
slowest intializers :
libSystem.B.dylib : 7.72 milliseconds (0.5%)
libMainThreadChecker.dylib : 38.77 milliseconds (2.8%)
libglInterpose.dylib : 565.71 milliseconds (41.3%)
xxx : 580.15 milliseconds (42.4%)

在 hook_cpp_init.mm 中也有 static 变量，这些变量不需要通过 __mod_init_func 来初始化吗？
static std::vector<MemoryType> *g_initializer;
static int g_cur_index;
static MemoryType g_aslr;

你好 有关获取方法执行时间,你这边是怎么思路的呢?你是直接hook 底层方法objc_msgSend 吗?如果hook这个方法的话,会是我们方法执行时间会比没有hook执行时间长,请问你是怎么解决的呢?谢谢

• (void)EVTTabPageScrollView:(EVTTabPageScrollView *)tabPageScrollView didPageItemSelected:(EVTTabPageScrollViewPageItem *)pageItem withTabIndex:(NSInteger)tabIndex

感谢大佬的开源精神及扎实的基础。
在使用过程结合公司的情况也发现一些问题，研究了几天没有什么进展，就把问题抛出来：
1、如果 hook_cpp_init.mm 在主工程或者静态库中，能收集主工程及静态库的相关数据，但是收集不到动态库的，因为动态库的相关方法执行较早；
2、如果 将 hook_cpp_init.mm 在动态库中，即使保证在第一个执行，也无法收集其他动态库统计到。

希望有大师遇到类似的问题能一起讨论解决下。

#define QWLoadable __attribute((used, section(QWLoadableSegmentName "," QWLoadableSectionName )))

替换后 __attribute里面：
(used,section("__DATA" "," "QWLoadable"))
感觉多了一个逗号，虽然也能过
