iphone - 杀死应用程序后显示本地通知弹出窗口

Question

我在我的应用程序中实现了本地通知，我在以下情况下遇到了问题:

场景:应用程序启动，位置通知将在从当前日期起一周后显示在登录屏幕上，我使用凭据登录并在登录后双击设备的主页按钮(底部中心物理键)以调出最近使用的应用程序栏，然后点击并按住应用程序图标，以便能够终止应用程序。终止应用程序后，无需等待一周时间即可显示通知弹出窗口

代码如下:

- (void)applicationWillTerminate:(UIApplication *)application
{
    if (iPhoneClientConfig::getInstance()->getReminder() == RS_NONE) {
        [[UIApplication sharedApplication] cancelAllLocalNotifications];
    }
    else {
        int daysToAdd;
        NSString *alertText;
        UILocalNotification *localNotification = [[UILocalNotification alloc] init];
        [[UIApplication sharedApplication] cancelAllLocalNotifications];
        if (iPhoneClientConfig::getInstance()->getReminder() == RS_MONTH) {
            daysToAdd = 60*60*24*30;
            alertText = [Localization getLanguage:@"reminder_message_month"];
            localNotification.repeatInterval =  NSMonthCalendarUnit;
            [self generateAlertNotifications:daysToAdd withtext:alertText ];
        } else if (iPhoneClientConfig::getInstance()->getReminder() == RS_DAY) {
            daysToAdd = 60*60*24;
            alertText = [Localization getLanguage:@"reminder_message_day"];
            localNotification.repeatInterval =  NSDayCalendarUnit;
        } else if (iPhoneClientConfig::getInstance()->getReminder() == RS_HOUR) {
            daysToAdd = 60*60;
            alertText = [Localization getLanguage:@"reminder_message_hour"];
            localNotification.repeatInterval =  NSHourCalendarUnit;
        } else {
            if (iPhoneClientConfig::getInstance()->getReminder() != RS_WEEK) {
                LOG.error("%s: Unexpetected reminder repeat interval in configuration, fall back to week",__FUNCTION__);
            }
            daysToAdd = 60*60*24*7;
            alertText = [Localization getLanguage:@"reminder_message_week"];
            localNotification.repeatInterval =  NSWeekCalendarUnit;
            [self generateAlertNotifications:daysToAdd withtext:alertText];
        }

        NSDate *today = [NSDate date];
        NSDate *newDate = [today addTimeInterval:daysToAdd];
         NSLog(@"newDate:%@",newDate);
        // Set up the fire time
        localNotification.fireDate = newDate;
        localNotification.timeZone = [NSTimeZone defaultTimeZone];

        // Notification details and Set the action button
        localNotification.alertBody = alertText;
        localNotification.alertAction = [Localization getLanguage:@"local_notif_alert"];
        localNotification.soundName = UILocalNotificationDefaultSoundName;
        //Schedule LocalNotification
        [[UIApplication sharedApplication] scheduleLocalNotification:localNotification];
        NSLog(@"local_notif_alert:%@",localNotification);
        [localNotification release];
    }
}

我在控制台中有触发日期和本地通知，如下所示:

Date:2012-09-01 10:49:08 +0000

local_notif_alert:<UIConcreteLocalNotification: 0xd006d20>{fire date = Saturday, September 1, 2012 4:19:08 PM India Standard Time, time zone = Asia/Kolkata (IST) offset 19800, repeat interval = NSWeekCalendarUnit, repeat count = UILocalNotificationInfiniteRepeatCount, next fire date = Saturday, September 1, 2012 4:19:08 PM India Standard Time}

当然。一旦安排好，本地通知就有了自己的生命周期。
这是你必须做的:打电话

[[UIApplication sharedApplication] cancelAllLocalNotifications];

例如在 applicationWillTerminate: 中。

至于过早出现的意外通知:NSLog 通知详细信息并确保您安排正确。
