如何删除用户默认值在NSUserDefaults？ [英] How to delete a user default value in NSUserDefaults?

问题描述

也就是说，我的应用程式在开头设定了一些标准预设值。然后，这些值可能被用户覆盖。当用户弄乱了事情，我想把这些设置回我的应用程序默认值。据我所知，应用默认值是与用户默认值不同的字典，用户默认值只是覆盖那些应用默认值。但我还没有看到删除用户默认值的方法。任何想法？

I.e., my app sets some standard default values at the beginning. Then those values may get overridden by the user. And when the user messes things up, I want to set those settings back to my app default values. As I understand it, the app defaults are a different dictionary than the user defaults, and the user defaults just override those app defaults. But I haven't seen methods for deleting the user defaults. Any idea?

推荐答案

尝试 removeObjectForKey - 应该能够删除首选项。

Try removeObjectForKey -- that should give you the ability to remove a preference.
