更新日志

2018.09.12 由于iOS系统限制了注册本地推送的数量，最大的注册量为64条，且一旦超出64条，所有的推送都将失效，故而在添加推送的时候做了一个判断，超过64条后，将不添加，以免影响已经添加的推送。

前言

最近项目中涉及到了本地通知的功能，索性就模仿系统闹钟写了个demo，对于iOS系统闹钟，应该都比较熟悉，该demo，基本实现了系统闹钟的全部功能。该demo本地通知使用的是iOS10 推出的UserNotifications， 关于UserNotifications的介绍和使用，网上已有诸多文章，在此就不多做赘述。

UNNotificationsManager

关于闹钟所使用到的UserNotifications库 做了一个简单的封装, 包含了注册通知，添加通知，以及 一些通知组件的 实现方法，同时提供了可供 外部使用的收到推送的通知

extern NSString * const UNDidReciveRemoteNotifationKey;//收到远程通知时调用

extern NSString * const UNDidReciveLocalNotifationKey; //收到本地通知时

extern NSString * const UNNotifationInfoIdentiferKey; //本地通知userinfo 里 Identifer的key值

一些其他方法，以demo为准

//注册本地通知

+ (void)registerLocalNotification;

#pragma mark -- AddNotification

/* 添加通知

* identifer 标识符

* body 主体

* title 标题

* subTitle 子标题

* weekDay 周几

* date 日期

* repeat 是否重复

* music 音乐

*/

+ (void)addNotificationWithBody:(NSString *)body

title:(NSString *)title

subTitle:(NSString *)subTitle

weekDay:(NSInteger)weekDay

date:(NSDate *)date

music:(NSString *)music

identifer:(NSString *)identifer

isRepeat:(BOOL)repeat

completionHanler:(void (^)(NSError *))handler;

#pragma mark -- NotificationManage

/*

* identifer 标识符

* 根据标识符 移除 本地通知

*/

+ (void)removeNotificationWithIdentifer:(NSString *)identifer;

#pragma mark -- NSDateComponents

/*

* return 日期组件 时分秒

* ex 每天重复

*/

+ (NSDateComponents *)componentsEveryDayWithDate:(NSDate *)date;

#pragma mark -- UNNotificationContent

/* UNMutableNotificationContent 通知内容

* title 标题

* subTitle 子标题

* body 主体

*/

+ (UNMutableNotificationContent *)contentWithTitle:(NSString *)title

subTitle:(NSString *)subTitle

body:(NSString *)body;

#pragma mark -- UNNotificationTrigger

/* UNNotificationTrigger 通知触发器

* interval 通知间隔

* repeats 是否重复

*/

+ (UNNotificationTrigger *)triggerWithTimeInterval:(NSTimeInterval)interval repeats:(BOOL)repeats;

添加闹钟

普通闹钟

[UNNotificationsManager addNotificationWithContent:[UNNotificationsManager contentWithTitle:@"时钟" subTitle:nil body:nil sound:[UNNotificationSound soundNamed:self.music]] dateComponents:[UNNotificationsManager componentsWithDate:self.date] identifer:self.identifer isRepeat:self.repeats completionHanler:^(NSError *error) {

NSLog(@"add error %@", error);

}];

每天重复

[UNNotificationsManager addNotificationWithContent:[UNNotificationsManager contentWithTitle:@"时钟" subTitle:nil body:nil sound:[UNNotificationSound soundNamed:self.music]] dateComponents:[UNNotificationsManager componentsEveryDayWithDate:self.date] identifer:self.identifer isRepeat:self.repeats completionHanler:^(NSError *error) {

NSLog(@"add error %@", error);

}];

每周重复(周一，周二等)

[self.repeatStrs enumerateObjectsUsingBlock:^(NSString * _Nonnull obj, NSUInteger idx, BOOL * _Nonnull stop) {

NSInteger week = 0;

if ([obj containsString:@"周日"]) {

week = 1;

}else if([obj containsString:@"周一"]){

week = 2;

}else if([obj containsString:@"周二"]){

week = 3;

}else if([obj containsString:@"周三"]){

week = 4;

}else if([obj containsString:@"周四"]){

week = 5;

}else if([obj containsString:@"周五"]){

week = 6;

}else if([obj containsString:@"周六"]){

week = 7;

}

[UNNotificationsManager addNotificationWithContent:[UNNotificationsManager contentWithTitle:@"闹钟" subTitle:nil body:nil sound:[UNNotificationSound soundNamed:self.music]] weekDay:week date:self.date identifer:self.identifer isRepeat:YES completionHanler:^(NSError *error) {

NSLog(@"add error %@", error);

}];

}];

}

铃声

这里无法获取系统铃声和震动类型，自己在网上找了点铃声素材。 系统铃声需要caf格式，MP3和caf 格式相互转化方法如下

//控制台输入

afconvert xxx.mp3 xxx.caf -d ima4 -f caff -v

通知栏选项

首先注册通知的时候需要UNNotificationCategory 以及UNNotificationAction

UNNotificationAction *action1 = [UNNotificationAction actionWithIdentifier:actionFiveMin title:@"5分钟后" options:UNNotificationActionOptionNone];

UNNotificationAction *action2 = [UNNotificationAction actionWithIdentifier:actionHalfAnHour title:@"半小时后" options:UNNotificationActionOptionNone];

UNNotificationAction *action3 = [UNNotificationAction actionWithIdentifier:actionOneHour title:@"1小时后" options:UNNotificationActionOptionNone];

UNNotificationAction *action4 = [UNNotificationAction actionWithIdentifier:actionStop title:@"停止" options:UNNotificationActionOptionNone];

UNNotificationCategory *category = [UNNotificationCategory categoryWithIdentifier:identiferStr actions:@[action1, action2,action3, action4] intentIdentifiers:@[] options:UNNotificationCategoryOptionNone];

UNNotificationCategory *stopCategory = [UNNotificationCategory categoryWithIdentifier:categryStopIdf actions:@[action4] intentIdentifiers:@[] options:UNNotificationCategoryOptionNone];

[center setNotificationCategories:[NSSet setWithArray:@[category,stopCategory]]];

然后在设置UNMutableNotificationContent的时候需要设置对应的categoryIdentifier 这里区分了是否设置了稍候提醒

+ (void)addNotificationWithContent:(UNNotificationContent *)content identifer:(NSString *)identifer trigger:(UNNotificationTrigger *)trigger completionHanler:(void (^)(NSError *))handler {

//设置 category

UNMutableNotificationContent *aContent = [content mutableCopy];

if ([identifer hasPrefix:@"isLater"]) {

aContent.categoryIdentifier = categryLaterIdf;

}else {

aContent.categoryIdentifier = categryStopIdf;

}

[self addNotificationWithRequest:[UNNotificationRequest requestWithIdentifier:identifer content:aContent trigger:trigger] completionHanler:handler];

}

最后在用户点击导航栏控件的时候，根据identifier处理相应事件

//与导航控件交互的时候会调用

- (void)userNotificationCenter:(UNUserNotificationCenter *)center didReceiveNotificationResponse:(UNNotificationResponse *)response withCompletionHandler:(void (^)())completionHandler {

NSLog(@"%s", __func__);

[self handCommnet:response];

completionHandler();

}

-(void)handCommnet:(UNNotificationResponse *)response

{

NSString *actionIdef = response.actionIdentifier;

NSDate *date;

if ([actionIdef isEqualToString:actionStop]) {

return;

}else if ([actionIdef isEqualToString:actionFiveMin]) {

date = [NSDate dateWithTimeIntervalSinceNow:5 * 60];

}else if ([actionIdef isEqualToString:actionHalfAnHour]) {

date = [NSDate dateWithTimeIntervalSinceNow:30 * 60];

}else if ([actionIdef isEqualToString:actionOneHour]) {

date = [NSDate dateWithTimeIntervalSinceNow:60 * 60];

}

if (date) {

[UNNotificationsManager addNotificationWithContent:response.notification.request.content identifer:response.notification.request.identifier trigger:[UNNotificationsManager triggerWithDateComponents:[UNNotificationsManager componentsWithDate:date] repeats:NO] completionHanler:^(NSError *error) {

NSLog(@"delay11111 %@", error);

}];

}

}

持续推送

本地铃声 时长小于30s。当手机处于后台，息屏的时候，铃声音乐是可以放完的的，手机处于活跃状态，只会持续到推送消失，经评论区 @bigcancancancan 指出，想要在活跃状态持续推送本地闹钟，需要用户在 设置-通知-横幅风格 选择持续。
