There is a complete example here that shows the basics of creating and using an ASINetworkQueue:

// Since this is a retained property, setting it to nil will release it

// This is the safest way to handle releasing things - most of the time you only ever need to release in your accessors

// And if you an Objective-C 2.0 property for the queue (as in this example) the accessor is generated automatically for you

[self setNetworkQueue:nil]; 

}

//... Handle success

NSLog(@"Request finished");

}
