Iphone 在UILocalNotification之后加载视图

我想在触摸屏上显示本地通知的警报视图，我的问题如下

UILocalNotification *localNotificationObject = [launchOptions objectForKey:UIApplicationLaunchOptionsLocalNotificationKey];

if (localNotificationObject) 
{

    firstObject = [[FirstViewController alloc]initWithNibName:@"FirstViewController" bundle:nil];

    NSLog(@"noti %@",[localNotificationObject.userInfo valueForKey:@"Key 1"]);

    // firstObject.title = @"FirstView";
    [self.window addSubview:firstObject.view];

}

else if(localNotificationObject)
{
    SecondViewController *secondObject = [[SecondViewController alloc]initWithNibName:@"SecondViewController" bundle:nil];

    NSLog(@"noti %@",[localNotificationObject.userInfo valueForKey:@"Key 2"]);

    [self.window addSubview:secondObject.view];

    //secondObject.title = @"Second View";
}

else if(localNotificationObject)
{
    ThirdViewController *thirdObject = [[ThirdViewController alloc]initWithNibName:@"ThirdViewController" bundle:nil];

    NSLog(@"noti %@",[localNotificationObject.userInfo valueForKey:@"Key 3"]);

    [self.window addSubview:thirdObject.view];

    // thirdObject.title = @"Third View";
}
else
{
    firstObject = [[FirstViewController alloc]initWithNibName:@"FirstViewController" bundle:nil];
    UINavigationController *navC = [[UINavigationController alloc]initWithRootViewController:firstObject];


    [self.window addSubview:navC.view]; 
}

它们是三个视图v1、v2、v3，我在这三个不同视图的按钮上触发了代码。下面给出了这三个视图的代码，不同视图的代码不同

notificationObject_ViewOne = [[UILocalNotification alloc]init];
notificationObject_ViewOne.fireDate = [NSDate dateWithTimeIntervalSinceNow:20];
notificationObject_ViewOne.timeZone = [NSTimeZone defaultTimeZone];
notificationObject_ViewOne.alertBody = @"You are notified";
notificationObject_ViewOne.alertAction = @"View 1";
notificationObject_ViewOne.applicationIconBadgeNumber = [[UIApplication sharedApplication]applicationIconBadgeNumber]+1;

NSDictionary *infoDict = [NSDictionary dictionaryWithObjectsAndKeys:@"Object 1", @"Key 1", nil];
notificationObject_ViewOne.userInfo = infoDict;


[[UIApplication sharedApplication]scheduleLocalNotification:notificationObject_ViewOne];
[notificationObject_ViewOne release];

SecondViewController *sec = [[SecondViewController alloc]initWithNibName:@"SecondViewController" bundle:nil];

[self.navigationController pushViewController:sec animated:YES];

[sec release];

在第二个视图中触发通知的代码是

notificationObject_ViewTwo = [[UILocalNotification alloc]init];
notificationObject_ViewTwo.fireDate = [NSDate dateWithTimeIntervalSinceNow:35];
notificationObject_ViewTwo.timeZone = [NSTimeZone defaultTimeZone];
notificationObject_ViewTwo.alertBody = @"You are notified";
notificationObject_ViewTwo.alertAction = @"View 2";
notificationObject_ViewTwo.applicationIconBadgeNumber = [[UIApplication sharedApplication]applicationIconBadgeNumber]+1;

NSDictionary *infoDict = [NSDictionary dictionaryWithObjectsAndKeys:@"Object 2", @"Key 2", nil];
notificationObject_ViewTwo.userInfo = infoDict;

[[UIApplication sharedApplication]scheduleLocalNotification:notificationObject_ViewTwo];

[notificationObject_ViewTwo release];

ThirdViewController *ThirdObj = [[ThirdViewController alloc]initWithNibName:@"ThirdViewController" bundle:nil];

[self.navigationController pushViewController:ThirdObj animated:YES];

[ThirdObj release];

现在，在应用程序代理中，我使用下面给出的代码处理通知

UILocalNotification *localNotificationObject = [launchOptions objectForKey:UIApplicationLaunchOptionsLocalNotificationKey];

if (localNotificationObject) 
{

    firstObject = [[FirstViewController alloc]initWithNibName:@"FirstViewController" bundle:nil];

    NSLog(@"noti %@",[localNotificationObject.userInfo valueForKey:@"Key 1"]);

    // firstObject.title = @"FirstView";
    [self.window addSubview:firstObject.view];

}

else if(localNotificationObject)
{
    SecondViewController *secondObject = [[SecondViewController alloc]initWithNibName:@"SecondViewController" bundle:nil];

    NSLog(@"noti %@",[localNotificationObject.userInfo valueForKey:@"Key 2"]);

    [self.window addSubview:secondObject.view];

    //secondObject.title = @"Second View";
}

else if(localNotificationObject)
{
    ThirdViewController *thirdObject = [[ThirdViewController alloc]initWithNibName:@"ThirdViewController" bundle:nil];

    NSLog(@"noti %@",[localNotificationObject.userInfo valueForKey:@"Key 3"]);

    [self.window addSubview:thirdObject.view];

    // thirdObject.title = @"Third View";
}
else
{
    firstObject = [[FirstViewController alloc]initWithNibName:@"FirstViewController" bundle:nil];
    UINavigationController *navC = [[UINavigationController alloc]initWithRootViewController:firstObject];


    [self.window addSubview:navC.view]; 
}

上面的代码是在应用程序委托文件的applicationdidefinish启动方法中编写的

所以我想在这里做的是当通知1的警报框出现时v1应该加载，当通知2的警报出现时v2应该加载

但问题是v1的加载非常完美，但是当涉及到v2和v3时，它们的userInfo为null，默认情况下加载v1。我在处理本地通知的UIApplication委托方法中也做了同样的操作，但结果仍然相同

请为我提供一些指导或相同的链接

提前感谢

您从不检查密钥的值，只需检查它是否存在。看看你的第一个if语句。幸好你用了其他的，否则你会把所有的都装进去
