NSOperationQueue完成

Question

我正在使用ASIHTTPRequest发出一个队列请求，但是我想知道是否有一种方法可以知道队列何时完成了所有请求，这里是我的代码的一部分

 for (int i=0; i< [result count]; i++) 
{
    Reportes *temp    =   [result objectAtIndex:i];
    ASIFormDataRequest *request     =   [ASIFormDataRequest requestWithURL:url];

    [request setTag:0];
    [request setDelegate:self];
    [request setPostValue:[[NSUserDefaults standardUserDefaults] stringForKey:USERNAME] forKey:POST_USUARIO];
    [request setPostValue:[KeychainWrapper keychainStringFromMatchingIdentifier:PIN_SAVED] forKey:POST_CLAVE];
    [request setPostValue:POST_IDSISTEMA_VALUE forKey:POST_IDSISTEMA];
    [request setPostValue:[self getMacAddress] forKey:POST_MAC];

    [request setPostValue:[[temp toNSDictionary] JSONRepresentation] forKey:@"value"];
    [[self queue] addOperation:request];

}

您可以实现以下方法

- (void)queueFinished:(ASINetworkQueue *)queue
{
    // You could release the queue here if you wanted
    if ([[self networkQueue] requestsCount] == 0) {
        [self setNetworkQueue:nil]; 
    }
    NSLog(@"Queue finished");
}

queueFinished是在所有请求完成后调用的函数。为了让它起作用，你必须调用

[[self queue] setQueueDidFinishSelector:@selector(queueFinished:)];

初始化队列时
