How to append querystring in url using objective c?

NSString *post = @"&username=adam&password=test"; NSData *postData = [post dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES]; NSString *postLength = [NSString stringWithFormat:@"%d", [postData length]]; NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease];

[request setURL:[NSURL URLWithString:@"http://ws.myurl.com/svc-public/iPhoneAuthenticate.aspx?uname=adam&pword=test"]];

[request setHTTPMethod:@"POST"];
[request setValue:postLength forHTTPHeaderField:@"Content-Length"];
[request setValue:@开发者_JAVA百科"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"];
[request setHTTPBody:postData];
NSData *returnData = [ NSURLConnection sendSynchronousRequest: request returningResponse: nil error: nil ];
NSString *response = [[NSString alloc] initWithData:returnData encoding:NSASCIIStringEncoding];
NSLog(response);
