推荐答案

使用 iPhone SDK 和封闭的应用程序，您无能为力.您可以让它在特定时间发送本地推送通知，但在用户手动打开您的应用之前不会执行您的代码.

There's not a whole lot you can do with the iPhone SDK and a closed app. You can have it send local push notifications at specific times, but that won't execute your code until the user manually opens your app.

我见过应用(例如闹钟应用等)所做的一件事是让应用保持打开状态，让手机进入睡眠状态，然后它仍会在您需要时执行代码.但这只有在用户不点击主页按钮时才有效.

One thing I've seen apps do (like alarm clock apps, etc) is have you leave your app open and just let the phone fall asleep and then it will still execute code when you want it to. But that only works as long as the user doesn't hit the home button.
