Ios5 本地通知停止出现？

我最近为客户端开发了一个包含本地通知的应用程序。在原始版本中，通知工作得非常好。但是，当客户端试图发布另一个版本时，仅更改了映像，而DB资源的代码没有更改，通知停止工作。现在我一直在调试代码，但什么也没找到。一切似乎都很好，但没有通知。同时，如果我运行早期的构建，它工作得非常完美。你能帮我找出哪里不对劲吗？非常感谢您抽出时间

NSTimeInterval diffTimeIntervalSinceNow = timeInterval; //time-interval after which notification should appear


    UILocalNotification *localNotification = [[UILocalNotification alloc] init]; //Create the localNotification object
    [localNotification setFireDate:[NSDate dateWithTimeIntervalSinceNow:diffTimeIntervalSinceNow]]; //Set the date when the alert will be launched using the date adding the time the user selected on the timer
    //[localNotification setRepeatInterval:notificationInterval];

    [localNotification setAlertAction:@"Launch"]; //The button's text that launches the application and is shown in the alert
    [localNotification setAlertBody:alertBody]; //Set the message in the notification from the textField's text
    [localNotification setHasAction: YES]; //Set that pushing the button will launch the application
    [localNotification setApplicationIconBadgeNumber:[[UIApplication sharedApplication] applicationIconBadgeNumber]+1]; //Set the Application Icon Badge Number of the application's icon to the current Application Icon Badge Number plus 1

    [[UIApplication sharedApplication] cancelAllLocalNotifications];
    [[UIApplication sharedApplication] scheduleLocalNotification:localNotification]; //Schedule the notification with the system
    [localNotification release];

这就是我一直在使用的代码。但这与早期版本中的代码完全相同。

我更正了您的代码：- 试试这个：-按钮动作或任何方法的内部

  [[UIApplication sharedApplication] cancelAllLocalNotifications];
       NSTimeInterval diffTimeIntervalSinceNow = timeInterval; //time-interval after which notification should appear


            UILocalNotification *localNotification = [[UILocalNotification alloc] init]; //Create the localNotification object
            [localNotification setFireDate:[NSDate dateWithTimeIntervalSinceNow:diffTimeIntervalSinceNow]]; //Set the date when the alert will be launched using the date adding the time the user selected on the timer
            //[localNotification setRepeatInterval:notificationInterval];

            [localNotification setAlertAction:@"Launch"]; //The button's text that launches the application and is shown in the alert
            [localNotification setAlertBody:alertBody]; //Set the message in the notification from the textField's text
            [localNotification setHasAction: YES]; //Set that pushing the button will launch the application
            [localNotification setApplicationIconBadgeNumber:[[UIApplication sharedApplication] applicationIconBadgeNumber]+1]; //Set the Application Icon Badge Number of the application's icon to the current Application Icon Badge Number plus 1


            [[UIApplication sharedApplication] scheduleLocalNotification:localNotification]; //Schedule the notification with the system
            [localNotification release];

对于此工作：-请在应用程序代理获取某些事件时检查此方法

-(void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification
{

}

要取消所有通知，请在

中使用此选项。您的客户端可能也修改了alertBody，并且新alertBody的长度太长？

未更改任何内容。我想代码是可以的，因为我用“fileMerge”比较了这两个类，没有任何区别。
