问题描述
谁能告诉我UIButton的突出显示"和选定"状态有什么区别?
Can anyone tell me What is the difference between Highlighted and Selected state of a UIButton?
推荐答案
根据:
突出显示状态.在跟踪过程中进入和退出触摸以及发生触摸事件时，控件都会进入此状态.
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
控件的选定状态.对于许多控件，此状态对行为或外观没有影响.但是其他子类的外观可能会有所不同，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.
这是状态之间的纯粹差异.
this is the pure difference between the states.
