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
