我没有使用 ASINetworkQueue 并通过一组 url 使用，并且我已经实现了 requestFinished: 方法，该方法可以正常调用。当请求没有得到响应时，我收到了崩溃。

你能请人帮我吗？

示例代码片段：

A 类（包装类扩展 ASIHTTPRequest）：

ASIHTTPRequest *httpRequest;

- (id)initWithURL:(NSString *)anURL errorInfo:(NSError **)error {
    if (self = [super init]) {
        NSURL *httpURL = [NSURL URLWithString:anURL];
    httpRequest = [self createASIRequest:httpURL];
    didFinishSelector = @selector(requestFinished:);
    didFailSelector = @selector(requestFailed:);
        return self;
    }
}

- (void)dealloc {
    if (httpRequest) {
       [httpRequest clearDelegatesAndCancel];
       [httpRequest release];
       httpRequest = nil;
    }
    [super dealloc];
}

- (ASIHTTPRequest *)createASIRequest:(NSURL *)url {
    ASIHTTPRequest *request = [[ASIHTTPRequest requestWithURL:url] retain];
    request.delegate = self;
    return request;
}

B类：

Request in loop:

 Class A *d = [[Class A alloc] initWithURL:url errorInfo:&pError];
 d.didFinishSelector = @selector(responseHandler:);
 d.didFailSelector = @selector(responseHandler:);

释放视图控制器后调用委托方法。因此，需要在释放视图控制器之前清理所有代表。这对我有用。
