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。
请注意，您无法设置自定义时间间隔。您必须使用默认的的。
Note that you can't set custom intervals. You must use the default ones provided by Apple.
