ios系统闹钟

• 添加闹钟效果图
  

  

• 收到通知效果图
  

  

• 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。
