以下のコードを使用して Web サービスにリクエストを送信し、応答を取得していますが、ここでは一度に 2 回リクエストを受け取りました。前もって感謝します。

 NSString *poststr=[NSString stringWithFormat:@"&cname=%@&conname=%@&email=%@",companynametxt.text,contactnametxt.text,contactEmailtxt.text];
NSLog(@"poststr %@",poststr);


NSData *postData = [poststr dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];


NSString *postLength = [NSString stringWithFormat:@"%d", [postData length]];

NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:[NSURL URLWithString: @"web servicess"]];
[request setHTTPMethod:@"POST"];
[request setHTTPBody:postData];

[request setValue:postLength forHTTPHeaderField:@"Content-Length"];
[request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"];
NSURLConnection *theConnection=[[NSURLConnection alloc] initWithRequest:request delegate:self];
NSLog(@"DATA%@",theConnection);
[theConnection release];
NSError *error;
NSURLResponse *response;
NSData *urlData=[NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];

NSString *filenameStr=[[NSString alloc]initWithData:urlData encoding:NSUTF8StringEncoding];

NSLog(@"filenameStr %@",filenameStr);

You are making two separate calls 

NSURLConnection *theConnection=[[NSURLConnection alloc] initWithRequest:request delegate:self];

and 

NSData *urlData=[NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];

use either one of them not both.
