1. 首先在您的 xib，(或代码)上设置日期选择器模式:时间(默认为日期和时间)

1. First on your xib, (or code) set the date picker mode: Time (Default is date & time)

系统假定firedate是当前日期，时间是用户选择的时间.这不是问题，因为您设置了重复间隔，因此它会起作用.我已经测试过了.

The system assumes that the firedate is the current date, and the time is the time the user have chosen. This is not a problem because you set a repeat interval so it will work. I have tested it.

UILocalNotification *localNotif = [[UILocalNotification alloc] init];
[localNotif setFireDate:datePicker.date];
[localNotif setRepeatInterval:NSDayCalendarUnit];
[[UIApplication sharedApplication] scheduleLocalNotification:localNotif];

PS:***使用 NSDateComponents 类将秒数设置为 0，以便将闹钟设置为在您想.您可以检查:
