在监控的函数里添加下段代码

最终函数调用信息依照顺序存在NSMutableArray backtrace 中

还需要添加头文件

#include 

#include 

void* callstack[128];

int frames = backtrace(callstack, 128);

char **strs = backtrace_symbols(callstack, frames);

int i;

NSMutableArray *backtrace = [NSMutableArray arrayWithCapacity:frames];

for (i = 0;i < frames;i++){

[backtrace addObject:[NSString stringWithUTF8String:strs[i]]];

}

free(strs);

NSLog(@"====================堆栈\n %@ \n",backtrace);
