How to delete a user default value in NSUserDefaults?

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?

Updated for Swift 3.0 code:

UserDefaults.standard.removeObject(forKey: "YOURKEY")

user_69014710

In Swift 4

    UserDefaults.standard.removeObject(forKey: "your_key")
    UserDefaults.standard.synchronize()
user_5963620

Swift way

UserDefaults.standard.removeObject(forKey: "aKey")
UserDefaults.standard.synchronize()
user_71583990
