Managing two NSURLConnection

Question

I want to do two async request from two different kml file, so I setup two requests first:

NSString *server1URL = [NSString stringWithFormat:...];
NSMutableURLRe         


        

Answer 1

How about assigning tags to each connection and checking the tags via an if/else or switch in the connectionDidFinishLoading?

Answer 2

- (void)connectionDidFinishLoading:(NSURLConnection *)connection{
    if( [connection isEqual: AConnection] ){
        // do connection A stuff
    }
    else if( [connection isEqual: BConnection] ){
        // do connection B stuff
    }  
}

Answer 3

Use GCD with sendSynchronousRequest: requests, they will be run in the background.

Example:

dispatch_queue_t queue = dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0);

dispatch_async(queue, ^{
    NSURLRequest *request = [NSURLRequest requestWithURL:url1];
    NSURLResponse *response;
    NSError *error;
    NSData *data1 = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];
    // do something with the data
});

dispatch_async(queue, ^{
    NSURLRequest *request = [NSURLRequest requestWithURL:url2];
    NSURLResponse *response;
    NSError *error;
    NSData *data2 = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];
    // do something with the data
});
