需求介绍：
很多时候我们不希望按钮多次连按
如果我们去写Enabled略显麻烦
这里提供一种控制按钮点击间隔时间的方面
我已封装成类型，方便使用
h文件声明
/********************这两个属性互斥********************//** 接受点击事件的时间间隔 */@property (nonatomic, assign) NSTimeInterval kj_AcceptEventTime;/** 接受点击事件执行处理之后的时间间隔 */@property (nonatomic, assign) NSTimeInterval kj_AcceptDealTime;/********************这两个属性互斥********************/
m文件实现
