  试试这个，您可以通过选择 setDay ， setMonth ，....来更改intervall：

  NSCalendar *calendar = [NSCalendar currentCalendar];
  
  NSDateComponents *components = [[NSDateComponents alloc] init];
  [components setDay:3];
  
  NSDate *date3Days = [calendar dateByAddingComponents:components 
                                                 toDate:[NSDate date] 
                                                options:0];
  
  UIApplication* app = [UIApplication sharedApplication];
  NSArray*    oldNotifications = [app scheduledLocalNotifications];
  if ( oldNotifications ) {
      [app cancelAllLocalNotifications];
      app.applicationIconBadgeNumber = 0;
  }
  
  UILocalNotification* notifyAlarm = [[UILocalNotification alloc] init];
  if (notifyAlarm) {
      notifyAlarm.fireDate = date3Days;
      notifyAlarm.timeZone = [NSTimeZone defaultTimeZone];
      notifyAlarm.alertBody = NSLocalizedString( @"Push message", @"");
      notifyAlarm.soundName = @"sound.wav";
      [app scheduleLocalNotification:notifyAlarm];
  }

  如果要设置 UILocalNotifications 应该出现的特定时间，您可以创建上述解决方案的方法并循环显示您希望显示通知的日期的数组：

  NSArray *arrayNumbers = @[@5, @7, @14, @21, @30, @60, @90, @120];
  NSDictionary *dictNotifications = 
  [[NSUserDefaults standardUserDefaults]    objectForKey:kUserDefAppStarts];
  
  for ( NSNumber *bla in arrayNumbers ){
  
      NSString *strKey = [NSString stringWithFormat:@"%@%@", kUserDefAppStarts, bla];
      NSDictionary *dict = dictNotifications[strKey];
      NSString *strMessageQuestion = dict[kKeyMessage];
  
      [self createNotificationWithNumberOfDays:[bla integerValue]
                                    andMessage:strMessageQuestion
                                      userInfo:dict];
  }
  

  这是你必须打电话的方法

  + (void)createNotificationWithNumberOfDays:(int)days 
                                  andMessage:(NSString *)message 
                                    userInfo:(NSDictionary *)dict{
  
  NSCalendar *gregorian = [[NSCalendar alloc] initWithCalendarIdentifier:NSGregorianCalendar];
  NSDateComponents *components = [[NSDateComponents alloc] init];
  [components setDay:days];
  
  NSDate *dateAlert = [gregorian dateByAddingComponents:components toDate:[NSDate date] options:0];
  
  UIApplication *app = [UIApplication sharedApplication];
  UILocalNotification *notifyAlarm = [[UILocalNotification alloc] init];
  
  if( notifyAlarm ){
      [notifyAlarm setFireDate:dateAlert];
      [notifyAlarm setTimeZone:[NSTimeZone defaultTimeZone]];
      [notifyAlarm setSoundName:@"soundname"];
      [notifyAlarm setAlertBody:message];
      [notifyAlarm setUserInfo:dict];
      [app scheduleLocalNotification:notifyAlarm];
  }
  

  }

  如果您希望将来从当前时间开始安排UILocalNotification 20天，您可以执行以下操作：

  NSCalendar *currentCalendar = [NSCalendar currentCalendar];
  NSDateComponents *dateComp = [[NSDateComponents alloc] init];
  int desiredAmountOfMonths = 4;
  for (int month = 0; month < desiredAmountOfMonths; month++)
  {
      dateComp.month = month;
      dateComp.day = 20;
      NSDate *fireDate = [currentCalendar dateByAddingComponents:dateComp toDate:[NSDate date] options:NSCalendarMatchNextTimePreservingSmallerUnits];
  
      UILocalNotification *notification = [[UILocalNotification alloc] init];
      notification.fireDate = fireDate;
      notification.timeZone = [NSTimeZone defaultTimeZone];
  }
  

  您需要修改UILocalNotification以获取消息，声音等，然后在完成自定义后触发通知 .
