使用 NSThread 加载地图时，应用程序在交替运行时崩溃

我正在使用 NSThread 与主线程同时执行一些工作。我已在 iPhone 3G 上部署了该应用程序该应用程序在第一次运行时按预期工作。

但是，当我关闭该应用程序并再次运行它时，它立即崩溃。下次我运行该应用程序时，它又可以正常工作了。这不断重复。

我不知道为什么应用程序的早期运行会对下一次运行产生影响。请帮忙！

这是我的代码：

NSThread *th=[[NSThread alloc]initWithTarget:self selector:@selector(loadMap) object:nil];
[th start]; 

-(void) loadMap{

    NSAutoreleasePool * pool=[[NSAutoreleasePool alloc]init];

    //code to load MKMapView

    [pool release];

}

提前致谢

如果我在两次运行之间打开另一个地图应用程序，应用程序不会崩溃！如果我删除线程并串行加载地图，应用程序也可以正常工作

I am using NSThread to do some work concurrently with main thread. I've deployed the application on iPhone 3G
The application is working as expected in first run.

But, when I close the app and run it again, it crashes immediatly. The next time I run the app, it works fine again. this keeps on repeating.

I have no idea why earlier run of the app has an effect on the next run.
Please help!

Here is my code:

NSThread *th=[[NSThread alloc]initWithTarget:self selector:@selector(loadMap) object:nil];
[th start]; 

-(void) loadMap{

    NSAutoreleasePool * pool=[[NSAutoreleasePool alloc]init];

    //code to load MKMapView

    [pool release];

}

Thanks in advance

App won't crash if I open another map application in between two runs!
Also App works very fine if I remove the thread and load the map serially
