iphone - 我怎样才能从 ASINetworkQueue 中删除请求

Question

这是我用来取消下载的代码。

    NSArray *queueArray =  [downloadQueue operations];
    for (ASIHTTPRequest *request in queueArray) {
        NSString *objid = [request.userInfo objectForKey:Column_objectid];
        if ([objid isEqualToString:audioToDelete.objectId]) {
            [request clearDelegatesAndCancel];
            [request removeTemporaryDownloadFile];
            ...}}

但是在我打电话之后
[请求clearDelegatesAndCancel]

downloadQueue.operations 或 downloadQueue.requestsCount 仍然是相同的计数(downloadQueue 是我的 ASINetworkQueue)

如何从队列中删除它？或者我怎样才能得到我的 downloadQueue 的正确操作计数？

这样做:

NSArray *queueArray =  [downloadQueue operations];
for (ASIHTTPRequest *request in queueArray) {
    NSString *objid = [request.userInfo objectForKey:Column_objectid];
    if ([objid isEqualToString:audioToDelete.objectId]) {
        [request cancel];
    }
 }
