推荐答案

如果您的应用被暂停，则无法在后台执行此操作。但UILocalNotification支持循环通知。 您所要做的就是声明重复间隔： notif.repeatInterval = NSDayCalendarUnit;

You can't do it in background if your app is suspended. But UILocalNotification supports recurrent notifications. All you have to do is to declare the recurring interval: notif.repeatInterval = NSDayCalendarUnit;

你可以找到更多详细信息。

请注意，您无法设置自定义时间间隔。您必须使用默认的的由Apple提供。

Note that you can't set custom intervals. You must use the default ones provided by Apple.
