ios - 如何在 iOS 中创建 365 天的本地通知

Question

我正在通过收集 365 个英语“谚语”来创建一个应用程序。在我的应用程序中，我想使用本地通知（每天我的应用程序中的一句谚语应该通知给用户）。我想使用本地通知，而不是推送通知。是否可以每天（365 天）用不同的说法通知用户。谁能帮助我......

Answer 1

没有办法创建 365 不同的本地通知。根据文档，本地通知仅限于 64 个计划的本地通知。

但是您可以在用户启动您的应用程序时更新通知。如果通知的内容相同，您还可以安排定期发送通知

Answer 2

Yes you can.Just create array with 365 dictionaries. dictionary keys should be id and saying.

UILocalNotification *localNotif = [[UILocalNotification alloc]init];
 NSCalendar *calendar = [NSCalendar currentCalendar];
    NSDate *datePickerDate = [NSDate date];
    NSDateComponents *dateComponents = [calendar components:(NSYearCalendarUnit | NSMonthCalendarUnit | NSDayCalendarUnit) fromDate:datePickerDate];
    NSDateComponents *timeComponents = [calendar components:(NSHourCalendarUnit | NSMinuteCalendarUnit | NSSecondCalendarUnit) fromDate:datePickerDate];

    NSDateComponents *dateComps = [[NSDateComponents alloc]init];
    [dateComps setYear:[dateComponents year]];
    [dateComps setMonth:[dateComponents month]];

    [dateComps setDay:[dateComponents day] + 1];

    [dateComps setHour:[timeComponents hour] ];
    [dateComps setMinute:[timeComponents minute]];
    [dateComps setSecond:00];

    NSDate *fireDate = [calendar dateFromComponents:dateComps];
    //NSLog(@"%@",fireDate);
    localNotif.fireDate = fireDate;
    localNotif.soundName = UILocalNotificationDefaultSoundName;
    localNotif.alertAction = @"Alarm";
    localNotif.repeatInterval = NSDayCalendarUnit;
    localNotif.userInfo = [NSDictionary dictionaryWithObjectsAndKeys:@"1",@"id", nil];
    localNotif.alertBody = [saying with id 1];//you can use predicate here
    [[UIApplication sharedApplication]scheduleLocalNotification:localNotif];

in application delegate,

- (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification    {
       int i = [[localNotif.userInfo objectForKey:@"id"] intValue] + 1;
       localNotif.alertBody = [saying in index i ];
       [localNotif.userInfo setValue:i forKey:@"id"];
}
