Question

Does someone know a way to remove requests from an ASINetworkQueue in a persistent way? The reset function doesn’t seem to do the job. What I’m trying to do is the following

- (void)fillAndRunQueue:(ASINetworkQueue*)queue requests:(NSArray*)requests {  
    for (ASIHTTPRequest* request in requests) {  
        if ([request check]) { // Valid request => add it to the queue    
            [queue addOperation:request];  
        } else { // Invalid request => cancel immediatelly  
            // HOW TO REMOVE ALL PREVIOUS REQUESTS FROM THE QUEUE??  
            return;  
        }  
    }  

    [queue go];  
}

Answer 1

The two obvious options I can see are:

[queue cancelAllOperations];

or if you want more control:

[request cancel];

for each request you want to “remove” (this isn’t technically removing them, but may have a close enough effect for your purposes).

Although, I think [queue reset]; should also work – maybe you can explain exactly what happens when you try to use it?

If all else fails, releasing and then recreating the queue should remove everything.

Update

To further explain, I don’t think it’s possible to actually remove items from an NSOperationQueue, only to cancel them. (ASINetworkQueue is a subclass of NSOperationQueue.)
