Very simple posting data to server coding is below
- (IBAction)actionRegister:(id)sender
{
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:[NSURL URLWithString:strYourURL]];
[request setHTTPMethod:#"POST"];
//Check The Value what we entered in textField
NSLog(#"the company name is:%#",txtFieldCompanyName.text);
NSLog(#"the email is:%#",txtFieldEmail.text);
NSLog(#"the password is:%#",txtFieldPassword.text);
NSLog(#"the password again is:%#",txtFieldPasswordAgain.text);
//Pass The String to server
NSString *strParameters =[NSString stringWithFormat:#"comapny_name=%#&email=%#&password=%#&password_again=%#",txtFieldCompanyName.text,txtFieldEmail.text,txtFieldPassword.text,txtFieldPasswordAgain.text,nil];
//Check The Value what we passed
NSLog(#"the data Details is =%#", strParameters);
//Convert the String to Data
NSData *data1 = [strParameters dataUsingEncoding:NSUTF8StringEncoding];
//Apply the data to the body
[request setHTTPBody:data1];
//Create the response and Error
NSError *err;
NSURLResponse *response;
NSData *responseData = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&err];
NSString *resSrt = [[NSString alloc]initWithData:responseData encoding:NSASCIIStringEncoding];
//This is for Response
NSLog(#"got response==%#", resSrt);
if(resSrt)
{
NSLog(#"got response");
}
else
{
NSLog(#"faield to connect");
}
}

NSString *string = [NSString stringWithFormat:#"www.yourwebapiurl.php?format=json&username=%#", userNameTextField.text];//and so on
NSURL *url = [NSURL URLWithString:string];
NSURLRequest *request = [NSURLRequest requestWithURL:url];
// 2
AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:request];
operation.responseSerializer = [AFJSONResponseSerializer serializer];
[operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {
// 3
NSDictionary *responseDict = (NSDictionary *)responseObject;
NSLog(#"You have got the response ");
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
// 4
UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:#"Error Retrieving Weather"
message:[error localizedDescription]
delegate:nil
cancelButtonTitle:#"Ok"
