How to set Local Notification repeat interval on Prayer time different times? - ios

Question

In local notifications there is repeatInterval property where we can put the unit repeat intervals for minute, hour, day, week, year, etc.
I want that repeat interval on Prayer time hours and every day same process.
So every Prayer time hours the local notification comes.
Prayer time is everyday different times

Answer 1

You can't do it with repeat. Make a bunch of different make notifications - one for each day - for the next 30 days. When the user opens the app, then recreate them for the next 30.

Answer 2

You can set repeat interval as day and pass array of local notifications of different time.
myapp.scheduledLocalNotifications = arrayOfNOtifications;
this may help you : how to create multiple local notifications

Answer 3

i have done a app like this try this .
func scheduleNotification() {
let dateString = "2017-04-04 09:00:00"
let dateFormatter = DateFormatter()
var localTimeZoneName: String { return TimeZone.current.identifier }
var secondsFromGMT: Int { return TimeZone.current.secondsFromGMT() }
dateFormatter.timeZone = TimeZone(secondsFromGMT: secondsFromGMT)
dateFormatter.dateFormat = "yyyy-MM-dd HH:mm:ss"
let dateObj:Date = dateFormatter.date(from: dateString)!
let triggerDaily = Calendar.current.dateComponents([.hour,.minute,.second,], from: dateObj)
let trigger = UNCalendarNotificationTrigger(dateMatching: triggerDaily, repeats: true)
let content = UNMutableNotificationContent()
content.title = "mIdeas"
content.body = getRandomMessage()
content.sound = UNNotificationSound.default()
content.categoryIdentifier = "myCategory"
let request = UNNotificationRequest(identifier: "textNotification", content: content, trigger: trigger)
UNUserNotificationCenter.current().delegate = self
//this commented code is to remove the pre-seted notifications so if you need multiple times don't use this line of code
//UNUserNotificationCenter.current().removeAllPendingNotificationRequests()
UNUserNotificationCenter.current().add(request) {(error) in
if let error = error {
print("Uh oh! i had an error: \(error)")
}
}
}
call this function to set notification you can modify this func and add parameters to pass time

Answer 4

Yes you can push a notification at a particular time and day with a repeat option.
Follow the code below:
//1. catch the notif center
UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];
//2. I prefer removing any and all previously pending notif
[center removeAllPendingNotificationRequests];
//then check whether user has granted notif permission
[center getNotificationSettingsWithCompletionHandler:^(UNNotificationSettings * _Nonnull settings) {
if (settings.authorizationStatus != UNAuthorizationStatusAuthorized) {
// Notifications not allowed, ask permission again
[center requestAuthorizationWithOptions:(UNAuthorizationOptionBadge | UNAuthorizationOptionSound | UNAuthorizationOptionAlert)
completionHandler:^(BOOL granted, NSError * _Nullable error) {
if (!error) {
//request authorization succeeded!
}
}];
}
}];
//3. prepare notif content
UNMutableNotificationContent *content = [[UNMutableNotificationContent alloc] init];
content.title = [NSString localizedUserNotificationStringForKey:NSLocalizedString(#"Hello! Today's Sunday!!",nil) arguments:nil];
content.body = [NSString localizedUserNotificationStringForKey:NSLocalizedString(#"Sleep tight!",nil) arguments:nil];
content.sound = [UNNotificationSound defaultSound];
content.badge = #([[UIApplication sharedApplication] applicationIconBadgeNumber] + 1);
//4. next, create a weekly trigger for notif on every Sunday
NSDate* sundayDate = startDate;
NSDateComponents *components = [[NSDateComponents alloc] init];
while(true){
NSInteger weekday = [[NSCalendar currentCalendar] component:NSCalendarUnitWeekday fromDate:sundayDate];
if(weekday == 1){//sunday, stay asleep reminder . LOL
components.weekday = 1;
components.hour = 9;
components.minute = 0;
break;
}else{//keep adding a day
[components setDay:1];
sundayDate = [[NSCalendar currentCalendar] dateByAddingComponents:components toDate:sundayDate options:0];
}
}
//5. Create time for notif on Sunday
unsigned unitFlags = NSCalendarUnitYear | NSCalendarUnitMonth | NSCalendarUnitDay;
NSCalendar *calendar = [NSCalendar currentCalendar];
NSDateComponents *comps = [calendar components:unitFlags fromDate:sundayDate];
comps.hour = 9;
comps.minute = 0;
sundayDate = [calendar dateFromComponents:comps];
NSDateComponents *triggerWeekly = [[NSCalendar currentCalendar] components:NSCalendarUnitWeekday + NSCalendarUnitHour + NSCalendarUnitMinute fromDate:sundayDate];
UNCalendarNotificationTrigger *trigger = [UNCalendarNotificationTrigger triggerWithDateMatchingComponents:triggerWeekly repeats:YES];
//6. finally, add it to the request
UNNotificationRequest *request = [UNNotificationRequest requestWithIdentifier:#"LocalIdentifier" content:content trigger:trigger];
[center addNotificationRequest:request withCompletionHandler:^(NSError * _Nullable error) {
if (!error) {
NSLog(#"Local Notification succeeded");
} else {
NSLog(#"Local Notification failed");
}
}];
If you are looking for actionable items on the notification. You should add it somewhere in the center.
UNNotificationAction *snoozeAct = [UNNotificationAction actionWithIdentifier:#"Snooze"
title:NSLocalizedString(#"Snooze",nil) options:UNNotificationActionOptionNone];
UNNotificationAction *deleteAct = [UNNotificationAction actionWithIdentifier:#"Delete"
title:NSLocalizedString(#"Delete",nil) options:UNNotificationActionOptionDestructive];
UNNotificationCategory *category = [UNNotificationCategory categoryWithIdentifier:identifier
actions:#[snoozeAct,deleteAct] intentIdentifiers:#[]
options:UNNotificationCategoryOptionNone];
NSSet *categories = [NSSet setWithObject:category];
[center setNotificationCategories:categories];
content.categoryIdentifier = #"ActionIdentifier";
Make sure you set a different identifier for your notification request!
