I am trying to make POST request using NSURLConnection sendSynchronousRequest. It works great when I run app on Simulator, but on real device I got timeout error (NSURLErrorDomain" - code: -1001), my server works ok
My code:
NSMutableURLRequest * request = [NSMutableURLRequest requestWithURL:url
cachePolicy:NSURLRequestUseProtocolCachePolicy
timeoutInterval:30];
[request setURL:url];
[request setHTTPMethod:#"POST"];
[request setValue:postLength forHTTPHeaderField:#"Content-Length"];
[request setValue:#"application/json" forHTTPHeaderField:#"Accept"];
[request setValue:#"application/x-www-form-urlencoded" forHTTPHeaderField:#"Content-Type"];
[request setHTTPBody:postData];
NSError *error = nil;
NSHTTPURLResponse *response = nil;
NSData *urlData=[NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];
Why I see timeout? and it is only on device?

I am using the below code for send a request to web-service and get the response , but here i got the request twice at a time ,i dont where i did mistake,help me to come out from this issue. thanks in advance.
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.
I am sending two array and multiple value throw json but when i send this i am getting success code 200 and its response showing access denied pls any one give me right way to solve it **

Wanted to see your php code as well..Anyways please check whether the following example helps you out... Here I am not sending any dictionary values, adjust the code to your requirement :)
NSString *jsonRequest = #"{\"username\":\"user\",\"password\":\"pwd\"}";
NSLog(#"Request: %#", jsonRequest);
NSURL *url = [NSURL URLWithString:#"http://xxxyyyzzzz.php"];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:url];
NSData *requestData = [NSData dataWithBytes:[jsonRequest UTF8String] length:[jsonRequest length]];
[request setHTTPMethod:#"POST"];
[request setValue:#"application/json" forHTTPHeaderField:#"Accept"];
[request setValue:#"application/x-www-form-urlencoded" forHTTPHeaderField:#"Content-Type"];
[request setValue:[NSString stringWithFormat:#"%d", [requestData length]] forHTTPHeaderField:#"Content-Length"];
[request setHTTPBody: requestData];
[NSURLConnection connectionWithRequest:[request autorelease] delegate:self];
try this code
NSDictionary *dict = [NSDictionary
dictionaryWithObjectsAndKeys:oneRowColumn,#"oneRowCols",memberTid,#"table_title_id",totalRowStr,#"totRow",rowandColumn,#"tempColName",tableOptIdArray ,#"tempOptid",companyId,#"companyid",#"savecolumniphone",#"tag",nil];
NSString *jsonRequest = [dict JSONRepresentation];
NSURL *url = [NSURL URLWithString:#"http://xxxyyyzzzz.php"];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url
cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:60.0];
NSData *requestData = [NSData dataWithBytes:[jsonRequest UTF8String] length:[jsonRequest length]];
[request setHTTPMethod:#"POST"];
[request setValue:#"application/json" forHTTPHeaderField:#"Accept"];
[request setValue:#"application/json" forHTTPHeaderField:#"Content-Type"];
[request setValue:[NSString stringWithFormat:#"%d", [requestData length]] forHTTPHeaderField:#"Content-Length"];
[request setHTTPBody: requestData];
connection = [[NSURLConnection alloc]initWithRequest:request delegate:self];
I've done many searches but none of the code fragments I find seem to work for me. I have the following fragment in xcode for running within my iPhone app:
NSURL *url = [NSURL URLWithString:#"http://blah.blah.com/rec.php"];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
[request setHTTPMethod:#"POST"];
NSData *body = [#"data=crap" dataUsingEncoding:NSUTF8StringEncoding];
NSString *bodyLength = [NSString stringWithFormat:#"%d", [body length]];
[request setValue:bodyLength forHTTPHeaderField:#"Content-Length"];
[request setValue:#"application/x-www-form-urlencoded" forHTTPHeaderField:#"Content-Type"];
[request setHTTPBody:body];
NSData *responseData = [NSURLConnection sendSynchronousRequest:request returningResponse:NULL error:NULL];
The rec.php is called fine but the post data does not make it through. The entry $_POST['data'] is empty. Could anyone let me know what I'm doing wrong?
I am developing an application with REST full web service .Now i have some problem in this case ,ie string sent to a servier using put method. I am using the following code.
NSMutableURLRequest* request = [[NSMutableURLRequest alloc] initWithURL:[NSURL URLWithString:#"http://176.31.113.164/app/profil/add"]];
[request setValue:#"Digest adf#email.com:test" forHTTPHeaderField:#"Authorization"];
[request setValue:#"application/json" forHTTPHeaderField:#"Accept"];
[request setValue:#"application/json" forHTTPHeaderField:#"content-type"];
//[request setValue:#"application/x-www-form-urlencoded" forHTTPHeaderField:#"Content-Type"];
NSDictionary *dic=[[NSDictionary alloc]init ];
dic=[NSDictionary dictionaryWithObjectsAndKeys:#"15",#"#idUsers",#"17",#"#idProfils",#"ddduu",#"address",#"ddd",#"city",#"ddd",#"country",#"adf#email.com <mailto:adf#email.com>",#"email",#"1",#"enabled",#"fff55",#"firstName",#"fffdd3",#"lastName",#"fffffcc",#"nickName",#"test",#"password",#"0",#"phone",#"0",#"postCode",#"ROLE_USER",#"role", nil];
NSString *jsonString = [jsonWriter stringWithObject:dic];
NSData *postData= [jsonString dataUsingEncoding:NSUTF8StringEncoding allowLossyConversion:NO];
[request setHTTPBody:postData];
[request setHTTPMethod:#"PUT"];
[request setValue:postLength forHTTPHeaderField:#"Content-Length"];
NSURLConnection* _loginConnection=[[NSURLConnection alloc] initWithRequest:request delegate:self];
if (_loginConnection==NULL)
{
NSLog(#"Problem");
}
[_loginConnection start];
The received data is handled as this:
NSString* tempString =[NSJSONSerialization
JSONObjectWithData:_receivedData
options:kNilOptions
error:&error];
You can use ASIHTTP wrapper class to perform REST operations in your iOS application.
Download the latest ASIHTTP from here.

Dilshand's answer is ok , but you can use ASIFormDataRequest for ease. like follow
ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:url];
[request setRequestMethod:#"POST"];
[request setPostValue:mobileApplicationId forKey:#"mobileApplicationId"];
[request setPostValue:mobileApplicationVersion forKey:#"mobileApplicationVersion"];
[request setPostValue:userID forKey:#"userId"];
[request setPostValue:pass forKey:#"password"];
[request setValidatesSecureCertificate:NO];
[request setDelegate:self];
[request setTimeOutSeconds:60];
[request startAsynchronous];
