UIimageView 单击时间间隔10s

解决方法写一个按钮的分类，用runtime加个时间的属性，替换按钮点击的方法，按钮写一个全局的，定义block用于区分是否是正常的点击,
[[(AppDelegate*) [UIApplication sharedApplication].delegate floatballButton] sendActionsForControlEvents:UIControlEventTouchUpInside]
替换UIimageView单击的方法

按钮的分类代码

    /*-----以上主要是实现两个方法的互换,load是gcd的只shareinstance，果断保证执行一次-------*/
