iPhone - ASIHTTPRequest 线程安全吗？

Question

我有这个方法:

-(void)updateSomething
{
   NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];
   NSURL *url = [NSURL URLWithString:@"some url"];

   ASIFormDataRequest *httpRequest = [ASIFormDataRequest requestWithURL:url];
   [httpRequest startSynchronous];
   //some other stuff
   [pool drain];
}

我在applicationDidFinishLaunching上调用此方法如果我在主线程上调用它，它工作正常

[self getMyItems];

但是当我在单独的线程上调用它时，我收到“程序收到信号:“EXC_BAD_ACCESS”

[self performSelectorInBackground:@selector(getMyItems) withObject:nil];

知道如何解决这个问题吗？

当您可以使用 ASINetworkQueue 时，为什么要在单独的线程上执行单独的请求？

ASINetworkQueue *aQueue = [[ASINetworkQueue alloc] init];
[aQueue addOperation:requestToAdd];
[aQueue setDelegate:self];
[aQueue setRequestDidFinishSelector:@selector(requestFinished:)];
[aQueue setRequestDidFailSelector:@selector(requestFailed:)];
[aQueue setQueueDidFinishSelector:@selector(queueFinished:)];
[aQueue go];

ASINetworkQueue 是 NSOperationQueue 的子类，ASI*Requests 在单独的线程上运行。
