I want to test add local notification. I want it repeat daily/hourly. How can I do that?

NSCalendar *calendar = [NSCalendar autoupdatingCurrentCalendar]; // Get the current date NSDate *now = [NSDate date]; // Break the date up into components NSDateComponents *dateComponents = [calendar components:( NSYearCalendarUnit | NSMonthCalendarUnit | NSDayCalendarUnit ) fromDate:now]; NSDateComponents *timeComponents = [calendar components:( NSHourCalendarUnit | NSMinuteCalendarUnit | NSSecondCalendarUnit) fromDate:now]; // Set up the fire time NSDateComponents *dateComps = [[NSDateComponents alloc] init]; [dateComps setDay:[dateComponents day]]; [dateComps setMonth:[dateComponents month]]; [dateComps setYear:[dateComponents year]]; [dateComps setHour:[timeComponents hour]]; [dateComps setMinute:[timeComponents minute]]; [dateComps setSecond:[timeComponents second]+10]; // Notification will fire in one minute NSDate *itemDate = [calendar dateFromComponents:dateComps]; [dateComps release]; UILocalNotification *localNotif = [[UILocalNotification alloc] init]; if (localNotif == nil) return; localNotif.fireDate = itemDate; localNotif.timeZone = [NSTimeZone defaultTimeZone]; // Notification details localNotif.alertBody = @"Hello World"; // Set the action button localNotif.alertAction = @"View"; localNotif.soundName = UILocalNotificationDefaultSoundName; applicationIconBadgeNumber++; localNotif.applicationIconBadgeNumber = applicationIconBadgeNumber; // Schedule the notification [[UIApplication sharedApplication] scheduleLocalNotification:localNotif]; [localNotif release];

推荐答案

如果要在特定时间设置通知每天...然后你需要设置通知 repeatInterval property.iOS处理它; s拥有通知。只需添加这一行...你错过了。否则你的代码很好&将会有效。

If you want to set the Notifications at a particular time on daily ... .then you need to set the notification repeatInterval property.iOS handles of it;s own about the notification.Just add this single line ...which you missed out. Otherwise you code is fine & will work.

notif.repeatInterval = NSDayCalendarUnit;
