如何为特定日期设置本地通知，时间为中午 12 点和下午 6 点

Question

在我的应用程序中，我需要在中午 12 点和下午 6 点的特定日期触发虚假通知。我已经在“UILocalNotification”类别文件中创建并安排了本地通知。

UILocalNotification+TZT.h 文件：

#import <UIKit/UIKit.h>

@interface UILocalNotification (TZT)

//Create LocalNotification
+ (void)createLocalNotificaitonForDateForDate:(NSDate *)date
                                     withBody:(NSString *)body
                                 withUserInfo:(NSDictionary *)userInfo
                         withTimeInterValInfo:(NSArray *)timeInterValInfo
                                 withBtnTitle:(NSString *)btnTitle;

//Cancel All Local notificaitons
+ (void)cancelAllLocalNotifications;

@end

UILocalNotification+TZT.m 文件：

#import "UILocalNotification+TZT.h"

@implementation UILocalNotification (TZT)

    + (void)createLocalNotificaitonForDateForDate:(NSDate *)date
                                         withBody:(NSString *)body
                                     withUserInfo:(NSDictionary *)userInfo
                             withTimeInterValInfo:(NSArray *)timeInterValInfo
                                     withBtnTitle:(NSString *)btnTitle
    {
        UILocalNotification * localNotification = [[UILocalNotification alloc] init];

        localNotification.alertBody = body;
        localNotification.alertAction = btnTitle;
        localNotification.userInfo = userInfo;
        localNotification.timeZone = [NSTimeZone defaultTimeZone];
        localNotification.repeatInterval = 0;
        localNotification.soundName = UILocalNotificationDefaultSoundName;

        for (int i = 0; i < [timeInterValInfo count]; i++) {

            NSLog(@"timeInterValInfo = %ld",(long)[[timeInterValInfo objectAtIndex:i] integerValue]);

            date = [date dateByAddingTimeInterval:(long)[[timeInterValInfo objectAtIndex:i] integerValue]];

            localNotification.fireDate = date;

            [[UIApplication sharedApplication] scheduleLocalNotification:localNotification];
        }
        //localNotification.applicationIconBadgeNumber = [[UIApplication sharedApplication] applicationIconBadgeNumber] + 1;
    }

    + (void)cancelAllLocalNotifications
    {
        [[UIApplication sharedApplication] cancelAllLocalNotifications];
    }

在 Appdelegate class didFinishLaunchingWithOptions 方法中，我必须通过调用类别 class.

创建和安排本地通知

#pragma mark - UILocalNotification
- (void)setUpLocalNotification
{
    NSDate * firedDate = [TZTNSDateHandlings getDateMonthYearHyPhenFormat:@"31-07-2017 00:00:00" withHourMinSec:YES];

    NSArray * timeInterValArray = @[@"43200",@"64800"];

    NSDictionary * userInfoDic = @{@"receiverType":@"localNotification"
                                  };

    [UILocalNotification createLocalNotificaitonForDateForDate:firedDate
                                                      withBody:@"Sample local notification"
                                                  withUserInfo:userInfoDic
                                          withTimeInterValInfo:timeInterValArray
                                                  withBtnTitle:NSLocalizedString(@"localPush.btnTitle", nil)];
}

例如，7月31日中午12点和下午6点我想显示本地通知，所以我将静态日期设置为字符串然后转换为NSDate，在我创建NSArray后包含NSTimeInterVal值。

中午 12 点为 43200 秒，下午 6 点为 64800 秒，使用这些时间间隔值安排。

但是我也看不到本地通知模拟器和设备。

应用部署目标从iOS9.0

开始

所以我需要管理 iOS 9.0 及以下和 iOS 10. 及以上情况的本地通知？

我还需要遵循 iOS-10 说明吗？

请给我建议。

这不是触发通知的正确方法。使用 NSCalendar 获取日期组件。这是为您想要的日期和时间触发通知的功能。

-(void)fireNotificationonDate:(NSDate *)dateEnter onTime:(NSString *)strTime
{
    NSCalendar *calendar = [NSCalendar autoupdatingCurrentCalendar];
    NSDateComponents *timeComponents = [calendar components:( NSYearCalendarUnit | NSMonthCalendarUnit |  NSDayCalendarUnit | NSHourCalendarUnit | NSMinuteCalendarUnit | NSSecondCalendarUnit ) fromDate:dateEnter];
   [timeComponents setHour:[strTime integerValue]];
   [timeComponents setMinute:00];
   [timeComponents setSecond:0];
   [timeComponents setYear:[timeComponents year]];
   [timeComponents setMonth:[timeComponents month]];
   [timeComponents setDay:[timeComponents day]];
   NSDate *dtFinal = [calendar dateFromComponents:timeComponents];
   NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
   [formatter setDateFormat:@"yyyy-MM-dd HH:mm:ss Z"];

   NSString *fierDate = [formatter stringFromDate:dtFinal];
   NSLog(@"%@",fierDate);

   UILocalNotification *notification = [[UILocalNotification alloc] init];
   notification.fireDate = dtFinal;
   notification.alertBody = @"";
   notification.timeZone = [NSTimeZone defaultTimeZone];
   notification.soundName = UILocalNotificationDefaultSoundName;
   notification.applicationIconBadgeNumber = 1;

   [[UIApplication sharedApplication] scheduleLocalNotification:notification];
}

像这样调用上面的方法。我使用 DateComponent 在 2 天后获取日期。你可以传递你的约会对象。

NSCalendar *calendar = [NSCalendar currentCalendar];
NSDateComponents *comps = [NSDateComponents new];
comps.day = 2;
NSDate *twoDaysAfter = [calendar dateByAddingComponents:comps toDate:[NSDate date] options:0];

[self fireNotificationonDate:twoDaysAfter onTime:@"6"];
[self fireNotificationonDate:twoDaysAfter onTime:@"12"];

这是通知的 FireDate 的输出。中午 12 点和下午 6 点通知。
