following code describe simple example post method.(how can pass data post method)

you can use following code snippet, described in article:

here, simple describe how can use of post method.

1. set post string actual username , password.

nsstring *post = [nsstring stringwithformat:@"&username=%@&password=%@",@"username",@"password"]; 

2. encode post string using nsasciistringencoding , post string need send in nsdata format.

nsdata *postdata = [post datausingencoding:nsasciistringencoding allowlossyconversion:yes]; 

you need send actual length of data. calculate length of post string.

nsstring *postlength = [nsstring stringwithformat:@"%d",[postdata length]]; 

3. create urlrequest properties http method, http header field length of post string. create urlrequest object , initialize it.

nsmutableurlrequest *request = [[[nsmutableurlrequest alloc] init] autorelease]; 

set url going send data request.

[request seturl:[nsurl urlwithstring:[nsstring stringwithformat:@"http://www.abcde.com/xyz/login.aspx"]]]; 

now, set http method (post or get). write lines in code.

[request sethttpmethod:@"post"]; 

set http header field length of post data.

[request setvalue:postlength forhttpheaderfield:@"content-length"]; 

also set encoded value http header field.

[request setvalue:@"application/x-www-form-urlencoded" forhttpheaderfield:@"current-type"]; 

set httpbody of urlrequest postdata.

[request sethttpbody:postdata]; 

4. now, create urlconnection object. initialize urlrequest.

nsurlconnection *conn = [[nsurlconnection alloc]initwithrequest:request delegate:self]; 

it returns initialized url connection , begins load data url request. can check whether url connection done or not using if/else statement below.

if(conn) { nslog(@”connection successful”) } else { nslog(@”connection not made”); } 

5. receive data http request , can use delegate methods provided urlconnection class reference. delegate methods below.

- (void)connection:(nsurlconnection *)connection didreceivedata:(nsdata*)data 

above method used receive data using post method.

- (void)connection:(nsurlconnection *)connection didfailwitherror:(nserror *)error 

this method , can use receive error report in case of connection not made server.

- (void)connectiondidfinishloading:(nsurlconnection *)connection 

the above method used process data after connection has made successfully.
