重复推送参考了这篇文章，感谢作者：
UILocalNotification 本地推送周一到周五重复提醒

在之前的工作中，基本没有使用过本地推送，不过对推送也有过了解，至于重复推送就没有研究过了，此次项目中有设置重复推送的需求，于是记录如下。
在iOS8上本地推送有一个属性repeatInterval，用来设置重复间隔。看了上述文章后，便了解了重复推送的原理。如果需要设置每个星期的某几天出现推送，就需要根据当前时间算出接下来一周内需要设置的那几天，都注册上推送，再通过以下设置完成每周重复：

localNotification.repeatInterval = NSWeekCalendarUnit;

在iOS10上初始化本地推送时使用

UNCalendarNotificationTrigger *trigger = [UNCalendarNotificationTrigger triggerWithDateMatchingComponents:notificationComps repeats:YES];

实现的原理也基本上同iOS8上一致，就是设置好最近一周的推送，设置repeats:YES即可。
代码如下：
iOS 8

NSDate *now = [NSDate date]; NSCalendar *calendar = [[NSCalendar alloc] initWithCalendarIdentifier:NSCalendarIdentifierGregorian]; NSInteger unitFlags = NSCalendarUnitYear | NSCalendarUnitMonth | NSCalendarUnitDay | NSCalendarUnitWeekday | NSCalendarUnitHour | NSCalendarUnitMinute | NSCalendarUnitSecond; NSDateComponents *comps = [[NSDateComponents alloc] init]; comps = [calendar components:unitFlags fromDate:now]; NSDate *fireDate = nil; if (time > 0) { // 定时时间存在，以定时时间为准 fireDate = [NSDate dateWithTimeIntervalSinceNow:time]; } else { fireDate = [NSDate dateWithTimeIntervalSince1970:dateTime]; }for (NSInteger newWeekDay = 1; newWeekDay <= 7; newWeekDay++) { if (![supporDays containsObject:@(newWeekDay)]) { continue; }NSInteger temp = 0; NSInteger days = 0; temp = newWeekDay - comps.weekday; days = (temp >= 0 ? temp : temp + 7); NSDate *date = [fireDate dateByAddingTimeInterval:3600 * 24 * days]; // 1.创建通知 UILocalNotification *localNotification = [[UILocalNotification alloc] init]; // 设置通知显示的标题 if (@available(iOS 8.2, *)) { localNotification.alertTitle = title ? title : @""; } // 设置通知显示的内容 localNotification.alertBody = body ? body : @""; // 设置通知的发送时间,单位秒 localNotification.fireDate = date; // 每周重复 localNotification.repeatInterval = NSWeekCalendarUnit; //收到通知时App icon的角标 localNotification.applicationIconBadgeNumber = 1; //推送是带的声音提醒，设置默认的字段为UILocalNotificationDefaultSoundName localNotification.soundName = soundName; // 3.发送通知( : 根据项目需要使用) // 方式一: 根据通知的发送时间(fireDate)发送通知 NSMutableDictionary *newParam = [NSMutableDictionary dictionaryWithDictionary:param]; newParam[@"identifier"] = [NSString stringWithFormat:@"%@-%@", notificationId, @(newWeekDay)]; localNotification.userInfo = newParam; [[UIApplication sharedApplication] scheduleLocalNotification:localNotification]; }

iOS 10+

NSDate *now = [NSDate date]; NSCalendar *calendar = [[NSCalendar alloc] initWithCalendarIdentifier:NSCalendarIdentifierGregorian]; NSInteger unitFlags = NSCalendarUnitYear | NSCalendarUnitMonth | NSCalendarUnitDay | NSCalendarUnitWeekday | NSCalendarUnitHour | NSCalendarUnitMinute | NSCalendarUnitSecond; NSDateComponents *comps = [[NSDateComponents alloc] init]; comps = [calendar components:unitFlags fromDate:now]; // 使用 UNUserNotificationCenter 来管理通知 UNUserNotificationCenter* center = [UNUserNotificationCenter currentNotificationCenter]; //需创建一个包含待通知内容的 UNMutableNotificationContent 对象，注意不是 UNNotificationContent ,此对象为不可变对象。 UNMutableNotificationContent* content = [[UNMutableNotificationContent alloc] init]; content.title = title; content.body= body; UNNotificationSound *sound = [UNNotificationSound soundNamed:soundName]; content.sound = sound; content.userInfo = param; NSTimeInterval timeInterval = 0; if (time > 0) { timeInterval = time; } else { timeInterval = [[NSDate dateWithTimeIntervalSince1970:dateTime] timeIntervalSince1970] - [[NSDate date] timeIntervalSince1970]; }for (NSInteger newWeekDay = 1; newWeekDay <= 7; newWeekDay++) { if (![supporDays containsObject:@(newWeekDay)]) { continue; } NSInteger temp = 0; NSInteger days = 0; temp = newWeekDay - comps.weekday; days = (temp >= 0 ? temp : temp + 7); NSDate *date = [[NSDate dateWithTimeIntervalSinceNow:timeInterval] dateByAddingTimeInterval:3600 * 24 * days]; NSDateComponents *notificationComps = [[NSDateComponents alloc] init]; notificationComps = [calendar components:unitFlags fromDate:date]; UNCalendarNotificationTrigger *trigger = [UNCalendarNotificationTrigger triggerWithDateMatchingComponents:notificationComps repeats:YES]; UNNotificationRequest* request = [UNNotificationRequest requestWithIdentifier:[NSString stringWithFormat:@"%@-%@", notificationId, @(newWeekDay)] content:content trigger:trigger]; //添加推送成功后的处理！ [center addNotificationRequest:request withCompletionHandler:nil]; }
