Xcode：为什么“启用用户交互”出现两次？ [英] Xcode: Why does "User Interaction Enabled" appear twice?

问题描述

此问题适用于Xcode 3和4：为什么此复选框出现两次？ （在Identity检查器下，也在Attributes检查器下）。更重要的是，如何改变一个的价值不会影响另一个？

This question applies to Xcode 3 and 4: Why does this checkbox appear twice? (under the Identity inspector and also under the Attributes inspector). And more important, howcome changing the value of one doesn't affect the other?

推荐答案

在Identity Inspector中启用用户交互指的是辅助功能协议。这是辅助功能编程指南您可以勾选不同的特征来修改元素对设备上辅助功能系统的响应方式。

The User Interaction Enabled in the Identity Inspector is referring to the Accessibility protocol. Here is a link to the Accessibility Programming Guide You tick different traits to modify how the elements responds to the Accessibility systems on the device.

在属性检查器上，已启用用户交互正在应用于与特定元素的非辅助功能交互。

On the Attributes Inspector, the User Interaction Enabled is applying to non-Accessibility interaction with the particular element.

如果您想知道为什么要使用辅助功能，那么这是一个好Matt Gemmell发帖关于它为何重要。
