Question

我正在创建一个应用程序，通过收集365英语“谚语”。在我的应用程序中，我想使用本地通知（每天我的应用程序的说法应通知用户）。我想使用本地通知，而不是推送通知。可以每天（365天）通知用户不同的说法。任何人都可以帮助我.....

Answer 1

无法创建365种不同的本地通知。根据{{3}}本地通知仅限于64个预定的本地通知。

但是，当用户启动您的应用时，您可以更新通知。如果通知内容相同，您还可以在documentation

上安排发送通知

Answer 2

是的，你可以。只需创建365个字典的数组。字典键应该是id和说。

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];

在应用程序委托中，

- (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"];
}
