Settings.app中的应用首选项(App preferences in Settings.app)

Settings.app中的应用首选项(App preferences in Settings.app)

我正在尝试在我的应用程序设置中实现类似于“清除历史记录”和“清除Cookie”的单元格（请参见屏幕截图）：

我已经实现了一些使用切换开关和多值选项的设置。

当我编辑Root.plist时，项目的唯一选项是组，多值，滑块，文本字段，标题和切换开关。 我正在尝试复制“清除历史记录”（即按一次并清除数组），它不存储任何设置或首选项，它是一次性事件。

我希望这是有道理的。 这是如何实现的？

谢谢你的帮助。

I'm trying to achieve something similar to the "Clear History" and "Clear Cookies" cells in my apps settings (see screenshot):

I already have a few settings implemented that use toggle switches and Multi Value options.

When I edit my Root.plist the only options for an item are group, multi value, slider, text field, title & toggle switch. I'm pretty much trying to replicate the "Clear History" (ie press it once and clear an array), it doesn't store any settings or preferences, it's a one off event.

I hope that makes sense. How is this achieved?

Thanks for your help.

暂时没有办法做到这一点，所以你必须找到另一个解决方案。

您可以简单地使用一个开关，并在每次启动应用程序时检查它并以编程方式重置开关（从iOS4开始）:)

There is no way to do this (yet), so you'll have to find another solution.

You could simply use a switch and check it every time your app is started for this purpose and resetting the switch programmatically (since iOS4) :)
