👆👆👆👆👆👆👆堆栈👆👆👆👆👆👆👆

用法

//在main函数里，或者任何你想开始监控的地方调用startMonitor，就可以了
//一般在main，或者application:didFinishLaunchingWithOptions:函数里。
[KKThreadMonitor startMonitor];

//在KKThreadMonitor.m文件里，可根据需求修改这两个值
#define KK_THRESHOLD 40   //表示线程数量超过40，就打印所有线程堆栈(根据自己项目来定！！！)
static const int threadIncreaseThreshold = 10;  //表示一秒钟新增加的线程数量（新建的线程数量 - 销毁的线程数量）超过10，就打印所有的线程堆栈

说明

打印线程堆栈，我目前是用自己另外一个库KKCallStack。
