基于Swift实现仿IOS闹钟
仿 iOS 系统闹钟
- 添加闹钟效果图
- 收到通知效果图
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，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。
