小弟的代码：
UILocalNotification *notification = [[UILocalNotification alloc] init];
if (notification != nil)
{
NSDate *now = [NSDate new];
notification.fireDate = [now dateByAddingTimeInterval:10];
notification.timeZone = [NSTimeZone defaultTimeZone];
notification.alertBody = @"测试";
notification.soundName = UILocalNotificationDefaultSoundName;
notification.applicationIconBadgeNumber = 1;
[[UIApplication sharedApplication] scheduleLocalNotification:notification];
[notification release];
}.
现在的问题是，程序在后台时可以弹出一个推送通知，但是手机桌面上程序的icon图标数字不能改变，这是什么原因啊？
------解决方案--------------------
收到通知时再刷新一下图标?
