NSURLRequest throwing runtime error

Trying to create a request only to have a runtime error thrown. Method initiating the request:

- (void)loadMemberData {

    //build URL
    NSMutableString *url = [[NSMutableString alloc] initWithString:appDelegate.apiURL];
    [url appendFormat:@"&subaction=singlestat&memberID=%d", [[NSUserDefaults standardUserDefaults] integerForKey:@"memberID"]];

    NSURL *tempURL = [[NSURL alloc] initWithString:url];
    NSLog(@"URL: %@", tempURL);

    //Create conn
    NSURLRequest *request = [[NSURLRequest alloc] requestWithURL:tempURL];
    NSLog(@"%@", request);
    //conn = [[NSURLConnection alloc] initWithRequest:request delegate:self];
    //[request release];

}

The URL logs correctly. I have even checked the object type to make sure everything is correct, and all seems good. No compile time errors or warnings. Stack Trace & Log:

terminate called after throwing an instance of 'NSException'

You should be doing

NSURLRequest *request = [NSURLRequest requestWithURL:tempURL];

The requestWithURL: creates NSURLRequest objects that are autorelease-d.

The actual error message says "unrecognized selector" because requestWithURL: is a class method, but you are using it like an instance method.
