【问题描述】：

我有一个本地通知。像这样 ;

NSNumberFormatter *faturaSonOdemeGunuFormatter = [[NSNumberFormatter alloc] init];
[faturaSonOdemeGunuFormatter setNumberStyle:NSNumberFormatterNoStyle];
NSNumber *faturaSonOdemeGunuNumber = [faturaSonOdemeGunuFormatter numberFromString:_txtFaturaGunu.text];

NSDate *currentDate = [NSDate date];
NSCalendar * calendar = [NSCalendar currentCalendar];
[calendar setTimeZone:[NSTimeZone systemTimeZone]];
NSDateComponents* components = [calendar components:NSYearCalendarUnit|NSMonthCalendarUnit|NSDayCalendarUnit | NSHourCalendarUnit | NSMinuteCalendarUnit fromDate:currentDate];

[components setTimeZone:[NSTimeZone systemTimeZone]];
[components setHour:12];
[components setMinute:40];
[components setDay: faturaSonOdemeGunuNumber.integerValue -3];

NSDate *test = [calendar dateFromComponents:components];


// Schedule the notification
UILocalNotification* localNotification = [[UILocalNotification alloc] init];
localNotification.fireDate = test;
localNotification.alertBody = [NSString stringWithFormat:@"%@ Faturanıza 3 gün kaldı.",_txtFaturaAdi.text];
localNotification.alertAction = @"Faturayı göster";
localNotification.timeZone = [NSTimeZone systemTimeZone];
localNotification.applicationIconBadgeNumber = [[UIApplication sharedApplication] applicationIconBadgeNumber] + 1;

[[UIApplication sharedApplication] scheduleLocalNotification:localNotification];

// Request to reload table view data
[[NSNotificationCenter defaultCenter] postNotificationName:@"reloadData" object:self];

此代码不会重复。我想在 faturaSonOdemeGunuNumber integerValue 日每个月重复本地通知。它应该从 sonOdemeGunuNumber -3 开始（例如用户写 17。它应该从 14 开始）并且它应该在每个月发出通知直到 faturaSonOdemeGunuNumber 的一天。我的意思是它应该每天继续通知用户，直到选定的那一天。 我该怎么做？

谢谢！

【参考方案1】：

添加这个：

localNotification.repeatInterval = kCFCalendarUnitMonth; //For monthly repeats
localNotification.repeatInterval = kCFCalendarUnitDay; //For daily repeats 

【参考方案2】：

试试这个，

notification.repeatInterval= NSDayCalendarUnit;    //For day
notification.repeatInterval= NSWeekCalendarUnit;   //For Week 
notification.repeatInterval= NSMonthCalendarUnit;  //For Month
