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做了一个简单的封装,部分代码如下
//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。
