NSMutableURLRequest *urlRequest = [[NSMutableURLRequest alloc] initWithURL:[NSURL URLWithString:@"http://api.mySmsGateWay.com/http/sendmsg"]];
NSString *userUpdate =[NSString stringWithFormat:@"user=%@&password=%@&api_id=%@&to=%@&text=%@",_username,_password,_apiID,[_numbers componentsJoinedByString:@","],_txtMsg.text, nil];
//create the Method "GET" or "POST"
[urlRequest setHTTPMethod:@"POST"];
//Convert the String to Data

I'm using an SMS gateway which uses HTTP. I created a request using tutorials and questions on stackoverflow etc. but there's something wrong. When I enter the URL manually I can use the gateway without any problems but I cannot do it programmatically so I thought probably my code is not right. Appreciate any help!
NSString *post = [NSString stringWithFormat:@"user=%@&password=%@&api_id=%@&to=%@&text=%@",_username,_password,_apiID,[_numbers componentsJoinedByString:@","],_txtMsg.text]; NSData *postData = [post dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES]; NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init]; [request setURL:[NSURL URLWithString:@"http://api.mySmsGateWay.com/http/sendmsg"]]; [request setHTTPMethod:@"POST"]; [request setHTTPBody:postData]; NSError *error = [[NSError alloc] init]; NSHTTPURLResponse *responseCode = nil; NSData *oResponseData = [NSURLConnection sendSynchronousRequest:request returningResponse:&responseCode error:&error]; if([responseCode statusCode] != 200){ NSLog(@"Error getting, HTTP status code %i", [responseCode statusCode]); } NSLog (@"%@", [[NSString alloc] initWithData:oResponseData encoding:NSUTF8StringEncoding]);
