UILocalNotification 和 iOS 4.2
伙计们 ：） 我在应用程序中使用本地通知，并为 UILocalNotification 提供操作，以便用户可以在通知触发时打开应用程序。我很确定在 iOS 4.2 之前，当用户点击操作按钮时，警报声音会立即停止。但是当我在 iOS 4.2 模拟器上运行我的应用程序时，声音会一直播放到结束，这对我来说非常糟糕，因为声音文件相当长 - 大约 30 秒。我不想缩短警报声音，因为它是一个警报应用程序。但是，如果用户单击本地通知警报视图的“关闭”按钮，声音会同时停止。您知道是否有任何解决方法可以在用户单击操作按钮时停止警报声？预先非常感谢，我真的很期待您的建议。快乐编码:)
guys :)
I'm using local notification in my application and I provide action for the UILocalNotification so that the user can open the application when the notification fires. I'm pretty sure that before iOS 4.2, when the user taps the action button, the alert sound was stopped immediately. But when I run my application on iOS 4.2 simulator, the sound plays until it reaches its end, which is very bad for me, because the sound file is pretty long - around 30 seconds. I don't want to shorten the alert sound, because it's an alarm application. But if the user clicks the "Close" button of the local notification alert view, the sound is stopped at the very same moment. Do you know if there is any workaround to stop the alarm sound when the user clicks the action button? Huge thanks in advance, I'm really looking forward for your advices. Happy coding :)

这似乎是 iOS 4.2 中的一个错误（而不仅仅是模拟器中）。我找不到任何方法可以在播放过程中取消声音，因为取消通知不起作用。
This appears to be a bug in iOS 4.2 (and not just in the simulator). I can't find any way to cancel a sound in mid-playback, as canceling the notification doesn't do it.
我在黑暗中刺探这个，但是当用户单击操作按钮时，您可以播放“无声”声音吗？从而覆盖当前播放的声音？
I stabbing in the dark on this one, but can you play a "silent" sound when the user clicks the action button? Thereby overriding the currently playing sound?
