1. 原生方法实现

    #pragma mark - private method
    // 启动本地通知
    - (void)setupLocalNoti
    {
        UILocalNotification *localNotif = [[UILocalNotification alloc] init];
        if (localNotif == nil)
            return;
        
        localNotif.fireDate = [NSDate dateWithTimeIntervalSinceNow:5];
        localNotif.timeZone = [NSTimeZone defaultTimeZone];
        // Notification details
        localNotif.alertBody = @"吃饭时间到了，通知提醒 。。。。。。。。";
        // Set the action button
        localNotif.alertAction = @"View";
        localNotif.soundName = UILocalNotificationDefaultSoundName;
        localNotif.applicationIconBadgeNumber = 1;
        // Specify custom data for the notification
        localNotif.userInfo = [NSDictionary dictionaryWithObject:@"someValue" forKey:@"someKey"];
        // Schedule the notification
        [[UIApplication sharedApplication] scheduleLocalNotification:localNotif];
        
        
        //    NSArray * array = [[UIApplication sharedApplication] scheduledLocalNotifications];
        //    [[UIApplication sharedApplication] cancelAllLocalNotifications];
        //    [[UIApplication sharedApplication] cancelLocalNotification:localNotif];
    }
    
    #pragma mark - 本地通知 回调
    - (void)application:(UIApplication *)app didReceiveLocalNotification:(UILocalNotification *)localNotif
    {
        NSLog(@"======%@",localNotif.alertBody);
    }

2.第三方实现

    #import "ACPReminder.h"
    
    #pragma mark - private method
    // 启动本地通知
    - (void)setupLocalNoti
    {
        ACPReminder * localNotifications = [ACPReminder sharedManager];
        
        //Settings
        localNotifications.messages = @[@"11111", @"22222", @"33333", @"444444", @"55555"];
        localNotifications.timePeriods = @[@(1),@(2),@(3)]; //days
        localNotifications.appDomain = @"com.mydomain.appName";
        localNotifications.randomMessage = NO; //By default is NO (optional)
        localNotifications.testFlagInSeconds = YES; //By default is NO (optional) --> For testing purpose only!
        localNotifications.circularTimePeriod = YES; // By default is NO (optional)
        
        [localNotifications createLocalNotification];
    }
    
    #pragma mark - 本地通知 回调
    - (void)application:(UIApplication *)app didReceiveLocalNotification:(UILocalNotification *)localNotif
    {
        NSLog(@"======%@",localNotif.alertBody);
    }
