// Set the fire date/time
[localNotification setFireDate:dateToFire];
[localNotification setTimeZone:[NSTimeZone defaultTimeZone]];

Use CalendarComponentsto set the hour to 6, and set localNotification.repeatIntervalto NSDayCalendarUnit
使用CalendarComponents将小时设置为 6，并将localNotification.repeatInterval设置为 NSDayCalendarUnit
NSCalendar *calendar = [NSCalendar currentCalendar]; // gets default calendar
NSDateComponents *components = [calendar components:(NSYearCalendarUnit | NSMonthCalendarUnit | NSDayCalendarUnit | NSHourCalendarUnit | NSMinuteCalendarUnit) fromDate:[NSDate date]]; // gets the year, month, day,hour and minutesfor today's date
[components setHour:18];
[components setMinute:0];
localNotification.fireDate = [calendar dateFromComponents:components];
