闹钟应用程序如何在 iPhone 3.0 SDK 上运行?
iPhone SDK 3.0 上的闹钟如何工作?当应用程序关闭时,闹钟应用程序仍然运行并在触发警报时显示警报消息。我知道iOS 3.0不支持多任务处理。
How does the alarm clock work on iPhone SDK 3.0? When the app has closed, the alarm clock app still runs and shows and alert message when the alarm is triggered. I know that iOS 3.0 doesn't support multitasking.

iOS 3 不支持多任务处理,它是第 3 方可用的公共 API。然而,iOS 是(并且一直是)一个多任务操作系统。显然,Apple 应用程序(邮件、时钟等)可以在第三方之前访问此功能。
iOS 3 did not support multi-tasking it the public API available to 3rd parties. The iOS is (and always has been) a multi-tasking OS, however. Clearly Apple apps (Mail, Clock, etc.) had access to this capability before 3rd parties.
