 1.UIControlStateNormal
 1> 除开UIControlStateHighlighted、UIControlStateDisabled、UIControlStateSelected以外的其他情况，都是normal状态
 2> 这种状态下的按钮【可以】接收点击事件
 
 2.UIControlStateHighlighted
 1> 【当按住按钮不松开】或者【highlighted = YES】时就能达到这种状态
 2> 这种状态下的按钮【可以】接收点击事件
 
 3.UIControlStateDisabled
 1> 【button.enabled = NO】时就能达到这种状态
 2> 这种状态下的按钮【无法】接收点击事件
 
 4.UIControlStateSelected
 1> 【button.selected = YES】时就能达到这种状态
 2> 这种状态下的按钮【可以】接收点击事件
 
 二、让按钮无法点击的2种方法

 2> button.userInteractionEnabled = NO; 
 *【不会】进入UIControlStateDisabled状态，继续保持当前状态
