How to allocate custom time in UILocalnotification? - ios

Question

- (void)scheduleNotification :(int) rowNo
{
[[UIApplication sharedApplication] cancelAllLocalNotifications];
Class cls = NSClassFromString(#"UILocalNotification");
if (cls != nil) {
UILocalNotification *notif = [[cls alloc] init];
notif.timeZone = [NSTimeZone defaultTimeZone];
NSString *descriptionBody=[[remedyArray objectAtIndex:rowNo]objectForKey:#"RemedyTxtDic"];
NSLog(#"%#",descriptionBody);
notif.alertBody = [NSString stringWithString:descriptionBody];
notif.alertAction = #"Show me";
notif.soundName = UILocalNotificationDefaultSoundName;
notif.applicationIconBadgeNumber = 1;
NSDictionary *userDict = [NSDictionary dictionaryWithObject:notif.alertBody
forKey:#"kRemindMeNotificationDataKey"];
notif.userInfo = userDict;
[[UIApplication sharedApplication] scheduleLocalNotification:notif];
}
}
I have a column name frequency which is fetched from Sqldb where it contains the number of times notification should appear for a particular cell.
if frequency = 3 ..the notification should fire say 8 AM , 2PM then 8PM
if frequency = 4 ..the notification should fire say 8 AM , 12PM , 4PM then 8PM.
Is there a way to do it? If anyone can help me that would be great

Unfortunately, You can specify value for repeatInterval only of type NSCalendarUnit (day, week, month). So, I think, You need to create several Notifications with different fireDate, and specify for them repeatInterval = NSDayCalendarUnit
For example,
NSDate *currentTime = [NSDate date];
notification1.fireDate = [NSDate dateWithTimeInterval:SOME_INTERVAL sinceDate:currentTime];
notification1.repeatInterval = NSDayCalendarUnit;
notification2.fireDate = [NSDate dateWithTimeInterval:SOME_INTERVAL * 2 sinceDate:currentTime];
notification2.repeatInterval = NSDayCalendarUnit;
After user viewed some of notifications - You can cancel them.
Update.
You can also create NSDate from different components like this:
NSDateComponents *components = [[NSDateComponents alloc] init];
[components setWeekday:2]; // Monday
[components setWeekdayOrdinal:1]; // The first Monday in the month
[components setMonth:5]; // May
[components setYear:2013];
NSCalendar *gregorian = [[NSCalendar alloc]
initWithCalendarIdentifier:NSGregorianCalendar];
NSDate *date = [gregorian dateFromComponents:components];
Also You can set hour, minutes, seconds, timezone and other parameters.
