如果这不是提出此类问题的正确论坛，请指出正确的论坛。
我正在处理的应用使用用户的位置，并在满足某些条件时提醒用户。警报以振动和小文件的播放形式出现。在设备上测试期间，手机振动并且音频剪辑播放2秒钟（剪辑长约9秒）并且应用程序崩溃。崩溃在设备上是一致的。在模拟器上，偶尔会看到崩溃但不一致。
引发警报的触发器位于CLLocation类的委托方法中 - （void）locationManager：manager didUpdateToLocation：fromLocation：
这是代码片段（ivLocMgr是一个实例变量）
if ((!ivAlertAlreadyShown) && (<test for trigger condition)) {
ivAlertAlreadyShown = YES;
[self obviousNotification];
[ivLocMgr stopUpdatingLocation];
[ivLocMgr release], ivLocMgr = nil;
}
[ivLocMgr stopUpdatingLocation]可以;是根本原因？
非常感谢任何和所有帮助。 -S -

没有足够的代码来正确确定中止的原因。您收到的错误告诉您正在尝试访问已发布的变量。我会从那里开始，确保你没有在那里发布你的位置经理或其他变量。
