[英]Setting Reminder with a dueDate with Recurrence Rule iOS
Question : How do I properly set my reminder due date since I have a recurrence rule? 问题 :由于我有重复规则,如何正确设置提醒到期日期?
Here is what the reminder object looks like: 提醒对象如下所示:
EKReminder <0x1700cf490> {title = Dickens's CANINE GOLD WELLNESS doses[1.00]; **dueDate = (null)**; **completionDate = (null)**; priority = 0; calendarItemIdentifier = D1D99FEA-2BFA-4DB1-9D86-7FB26246B50A; alarms = (
"EKAlarm <0x1780a9420> {triggerInterval = -79200.000000}"
)}
The error I am getting is: 我得到的错误是:
Reminder Error=[A repeating reminder must have a due date.]
You can see in the code that I am fooling around with NSDateComponents as a solution since startDateComponents which I just set the month/day/year and local timezone of the reminder which will produce an all day reminder, which in this case is fine. 您可以在代码中看到我正在使用NSDateComponents作为解决方案,因为startDateComponents我只是设置了提醒的月份/日期/年份和本地时区,因此会产生一整天的提醒,在这种情况下很好。 I will probably move the date components and setting of the due date inside the recurrence section when it is done.
完成后,我可能会在重复部分中移动日期组件和到期日期的设置。
Here is my code: 这是我的代码:
-(void)setReminders:(NSString *)reminderText
andDate:(NSString *)reminderdate
andPetName:(NSString*)petName
andDose:(NSNumber *)dose {
EKEventStore *store = [[EKEventStore alloc] init];
NSDate * reminderNewDate = [self getDateFromString:reminderdate];
petName = [ConfigOps readProperty:kConfigOpsPetKey];
NSString *reminderTitle = [NSString stringWithFormat:@"%@'s %@", petName, reminderText];
NSUInteger doseCount = 0;
if ([dose integerValue] != 0 || dose != nil) {
doseCount = [dose integerValue];
}
else{
doseCount = 0;//NOTE: looks like purchases will have doses not reminders so set to 0 for now.
}
[store requestAccessToEntityType:EKEntityTypeReminder completion:^(BOOL granted, NSError *error) {
// access code here
EKReminder *new_reminder = [EKReminder reminderWithEventStore:store];
new_reminder.title = reminderTitle;
new_reminder.calendar = store.defaultCalendarForNewEvents;
//get the date components
NSDateComponents *comp = [[NSDateComponents alloc]init];
NSCalendar *gregorian = [[NSCalendar alloc]
initWithCalendarIdentifier:NSGregorianCalendar];
NSDateComponents *weekdayComponents =
[gregorian components:(NSDayCalendarUnit | NSMonthCalendarUnit | NSYearCalendarUnit |
NSWeekdayCalendarUnit) fromDate:reminderNewDate];
NSInteger day = [weekdayComponents day];
NSInteger month = [weekdayComponents month];
//NSInteger weekday = [weekdayComponents weekday];//future reference
NSInteger year = [weekdayComponents yearForWeekOfYear];
//Month is dose+month = end of reccurence
month = month + doseCount;
[comp setYear:year];
[comp setMonth:month];
[comp setDay:day];
NSDate *date = [gregorian dateFromComponents:comp];
NSTimeZone *myNSTimeZone = gregorian.timeZone;
NSDateComponents *start = new_reminder.startDateComponents;
start.timeZone = myNSTimeZone;
start.month = [weekdayComponents month];
start.day = [weekdayComponents day];
start.year = [weekdayComponents yearForWeekOfYear];
new_reminder.startDateComponents = start;
new_reminder.dueDateComponents = start;
new_reminder.completed = NO;
//Create alarm 22 hours before
double alarmAmountInSeconds = 60.0*60.0*22.0;
EKAlarm *alarm = [EKAlarm alarmWithRelativeOffset:(-1.0*alarmAmountInSeconds)];
[new_reminder addAlarm:alarm];
//new_reminder.alarms = [NSArray arrayWithObject:alarm];
//create nice text for note.
//Hey there! petName needs remindertext from your friendly clinic, clinicName!
new_reminder.notes = reminderText;
if (doseCount != 0) {
EKRecurrenceRule *recurranceRule = [[EKRecurrenceRule alloc] initRecurrenceWithFrequency:EKRecurrenceFrequencyMonthly
interval:1
end:[EKRecurrenceEnd recurrenceEndWithOccurrenceCount:doseCount]
];
new_reminder.calendar = [store defaultCalendarForNewReminders];
[new_reminder addRecurrenceRule:recurranceRule];
}
NSError *er;
//EKEventEditViewController
BOOL success = [store saveReminder:new_reminder commit:YES error:&er];
if (success) {
// Handle here
NSString *alertMessage = [NSString stringWithFormat:@"Reminder Created for\n%@", reminderTitle];
NSString *alertTitle = @"Please check your Reminders";
UIAlertView *alertR = [[UIAlertView alloc]initWithTitle: alertTitle
message: alertMessage
delegate: self
cancelButtonTitle:nil
otherButtonTitles:@"OK",nil];
[alertR show];
}
else{
//log error
NSLog(@" Reminder Error=[%@]", [er localizedDescription]);
//log to error table in database &inform Flurry?
}
}];
}
The method works if there is no recurrence set since it doesn't require a start date/due date. 如果没有重复设置,则该方法有效,因为它不需要开始日期/到期日期。
For those looking for Swift version: 对于那些寻找Swift版本的人:
func editReminder(r: EKReminder) -> Bool {
if(r.recurrenceRules.count > 0 && r.dueDateComponents == nil) {
let startDate = NSDate()
let dueDate: NSDate = NSDate(timeIntervalSinceNow: 31536000) // 1 year from now
let gregorian = NSCalendar(calendarIdentifier: NSCalendarIdentifierGregorian)
let unitFlags = NSCalendarUnit(UInt.max)
r.dueDateComponents = gregorian?.components(unitFlags, fromDate: dueDate)
}
var error: NSError?
return eventStore.saveReminder(r, commit: true, error: &error)
}
After some fixing of the date (I found was returning nil), I found that I have to set and end recurrence rule when adding a dose amount. 确定日期后(我发现返回零),我发现添加剂量时必须设置并结束重复规则。
Here is the code which gets rid of the error (which is pretty funny of Apple to have - kudos Apple!). 这是摆脱错误的代码(对于Apple来说,这很有趣-称赞Apple!)。
if (doseCount != 0) {
EKRecurrenceRule *recurranceRule = [[EKRecurrenceRule alloc] initRecurrenceWithFrequency:EKRecurrenceFrequencyMonthly
interval:1
end:[EKRecurrenceEnd recurrenceEndWithOccurrenceCount:doseCount]
];
new_reminder.calendar = [store defaultCalendarForNewReminders];
//FIX for : recuurence end - Reminder Error = [A repeating reminder must have a due date.]
EKRecurrenceEnd *endRec = [EKRecurrenceEnd recurrenceEndWithEndDate:date];
EKRecurrenceRule *recur = [[EKRecurrenceRule alloc]initRecurrenceWithFrequency:EKRecurrenceFrequencyDaily interval: 1 end:endRec];
unsigned unitFlags= NSYearCalendarUnit|NSMonthCalendarUnit | NSDayCalendarUnit | NSHourCalendarUnit |NSMinuteCalendarUnit|NSSecondCalendarUnit|NSTimeZoneCalendarUnit;
NSDateComponents *dailyComponents=[gregorian components:unitFlags fromDate:date];
[new_reminder setDueDateComponents:dailyComponents];
[new_reminder addRecurrenceRule:recur];
//add it.
[new_reminder addRecurrenceRule:recurranceRule];
}
Hope this helps someone get through this. 希望这可以帮助某人解决这个问题。
