如何在iOS 8中14天后重复本地通知&；9

注册通知的代码为：

   UIUserNotificationType types = UIUserNotificationTypeBadge | UIUserNotificationTypeSound | UIUserNotificationTypeAlert;
        UIUserNotificationSettings *mySettings = [UIUserNotificationSettings settingsForTypes:types categories:nil];
        [[UIApplication sharedApplication] registerUserNotificationSettings:mySettings];

以及安排通知的代码：

UILocalNotification *notification = [[UILocalNotification alloc] init];
[self setNotificationTypesAllowed];
if (notification)
{
    if (allowNotif)
    {
        notification.timeZone = [NSTimeZone defaultTimeZone];
        if ( [statusString isEqualToString:@"daily"]) {
            notification.fireDate = _timePick.date;

                notification.repeatInterval = NSCalendarUnitDay;
        }else if ( [statusString isEqualToString:@"weekly"]) {
            notification.fireDate = _timePick.date;

                notification.repeatInterval = NSCalendarUnitWeekOfYear;

        }else if ( [statusString isEqualToString:@"fortnightly"]) {
            notification.fireDate = [NSDate dateWithTimeIntervalSinceNow:60*60*24*14];;
            notification.repeatInterval = NSCalendarUnitMinute;

            //notification.repeatInterval = NSCalendarUnitYear;
        }else{
                notification.repeatInterval = 0;
        }
    }
    if (allowsAlert)
    {
        notification.alertBody = [NSString stringWithFormat:@"Do you really want to send message to %@",name];
    }
    if (allowsBadge)
    {

        notification.applicationIconBadgeNumber = [[UIApplication sharedApplication] applicationIconBadgeNumber] + 1;
    }
    if (allowsSound)
    {
        notification.soundName = UILocalNotificationDefaultSoundName;
    }
    notification.alertAction = @"Yes";
    notification.timeZone = [NSTimeZone defaultTimeZone];
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(showSMS) name:@"showSMS" object:nil];

    // this will schedule the notification to fire at the fire date
    [[UIApplication sharedApplication] scheduleLocalNotification:notification];

我可以每天和每周重复本地通知，但不是每两周重复一次，请帮助

将通知设置为每14天触发一次。您必须创建26个单独的UILocalNotifications，并将

重复间隔

设置为

NSYearCalendarUnit

（重复间隔必须设置为日历单位，并且iOS中没有14天日历单位）

---

另一种处理方法是取消

didReceiveLocalNotification

方法中的

UILocalNotification

，并在14天后安排一个新的通知。不过，此方法假定用户与通知交互，否则下一个通知将永远无法安排。

是@Nikos建议的，请尝试下面的方法e:

取消UILocalNotification

[[UIApplication sharedApplication] cancelAllLocalNotifications];

附表本地通知

UILocalNotification *notification = [[UILocalNotification alloc]init];
notification.userInfo = @{@"notification_identifier":@"After14Days"};
notification.fireDate = [[NSDate date] dateByAddingTimeInterval:(60*60*24*14)];
notification.alertBody = @"Text to display";
notification.repeatInterval = NSCalendarUnitDay;
[[UIApplication sharedApplication] scheduleLocalNotification:notification];

如果您有任何疑问，请告诉我。

如果用户在30天内未打开应用程序，则上述代码不会在每14天后重复通知。但问题要求在每14天后重复通知，而不是一次。@RamaniAshish是的，您是对的，我忘了添加一行重复通知。我编辑了我的答案，您可以请立即查看。如果用户在30天内未打开应用程序，则上述代码不会在每14天后重复通知。但问题要求在每14天后重复通知，而不是一次。@RamaniAshish是的，您是对的，我忘记添加一行重复通知。我编辑了我的答案，您现在可以看到。
