Can anyone tell me What is the difference between Highlighted and Selected state of a UIButton?

推荐答案

根据文档:

突出显示状态 控件.控件在跟踪期间进入和退出触摸以及发生触摸事件时进入此状态.

Highlighted state of a control. A control enters this state when a touch enters and exits during tracking and when there is a touch up event.

和

选定状态.对于许多控件，此状态对行为或外观没有影响.但是其他子类可能有不同的外观，具体取决于它们的 selected 状态.

Selected state of a control. For many controls, this state has no effect on behaviour or appearance. But other subclasses may have different appearance depending on their selected state.

这是各州之间的纯粹区别.

this is the pure difference between the states.
