UIButton事件。有什么不同？ [英] UIButton events. What's the difference?

问题描述

我遇到了一个问题，我的按钮应该保持按下，同时它显示从它调用的弹出窗口。 Popover是一些过滤器的选择器，过滤器显示在按钮本身上。当我点击它并显示弹出窗口时，无论如何都会取消选择。

I've encountered a problem where my button should remain "pressed down" while it shows popover called from it. Popover is selector for some filter and filter is shown on button itself. When I tap on it and it shows popover it becomes deselected no matter what.

我认为我必须重新定义它在触摸事件上的行为并使其不响应标准在内修改。然后我想知道其他事件的责任是什么？但是我在iOS库中找不到事件列表，而在StackOverflow中只有关于错误行为的问题或触地。

I think I have to redefine it's behavior on touch event and make it respond not to standart touch up inside. Then I wondered what are other events responsible for? But I couldn't find events list in iOS library and in StackOverflow are only questions about incorrect behavior of touch up inside or touch down.

那么触摸事件之间有什么区别？

So what's the difference betweeen touch events?

1. 触摸取消 - 当您触摸按钮但移开手指并且
   它仍然被取消选择？


2. 触地 - 右键点击。


3. 触地重复？


4. 触摸拖动输入??


5. 触摸拖动退出？


6. 触摸内拖？


7. 触摸外面？


8. 内部触摸 - 当你点击并释放剩余的按钮时，
   界限。它将UIButton状态更改为正常。


9. 在外面触摸 - 当你点击并释放按钮时，它的
   界限？

1. touch cancel - when you touch button but move your finger away and it remains deselected?
2. touch down - right on tap.
3. touch down repeat ??
4. touch drag enter ??
5. touch drag exit ??
6. touch drag inside ??
7. touch drag outside ??
8. touch up inside - when you tap and release button remaining in it's bounds . It changes UIButtons state to Normal.
9. touch up outside - when you tap and release button leaving it's bounds ?

其他IBActions不是由UIButton发送的，对吗？
这些事件如何改变UIButton的外观？喜欢突出显示或选择？

other IBActions are not sent by UIButton, right? Also how those events change UIButton's appearance? Like highlighted or selected?

我很感激关于IBActions的好文章的链接，因为我找不到它。

I'd appreciate a link on good article about IBActions, because I couldn't find it.
