IOS获取函数调用堆栈信息

导入头文件

#include 
#include 

如下代码放到方法里即可知道该方法调用的堆栈信息

    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 < 4;i++){
	 	[backtrace addObject:[NSString stringWithUTF8String:strs[i]]];
    }
    free(strs);
    NSLog(@"====================堆栈\n %@ \n",backtrace);
