iOS实现UIButton自动化点击埋点

思路：我们HOOK UIControl的 addtarget:action:forControlEvents方法，交换UIControl的 addtarget:action:forControlEvents 方法的实现， 在交换的方法中添加原来响应的同时，再添加一个埋点响应，该响应方法实现了点击埋点操作，同时要添加一个标记为，记录我们添加过 点击埋点响应了，防止外部再次添加响应的时候，我们这里重复添加埋点响应，同时，还要hook removeTarget:action:forControlEvents方法，在该方法中记录我们绑定的点击处理次数，当次数大于0时，进行埋点上报

一下是我们的实现代码
