macos - NSUserDefaults 是否安全地处理自动终止？

Question

苹果的文档说

NSUserDefaults temporarily disables sudden termination to prevent process killing between the time at which a default has been set and the time at which the preferences file including that default has been written to disk.

它是否也为自动终止执行此操作，或者我必须 synchronize当我怀疑可能会发生自动终止时(例如，当应用程序被隐藏时)？

Answer 1

它不需要专门为自动终止做任何事情。原因是自动终止的行为与 ⌘Q 没有不同(即，如果未启用突然终止，则调用 -[NSApp terminate:])和 NSUserDefaults已经处理 ⌘Q 就好了。
