iOS将数据发送给PHP

Question

I'm having problem sending information to the PHP file at my server. I need some favor , i give up and almost can give up with this problems ahead.

IBAction:-

- (IBAction)reg:(id)sender {
    NSInteger success = 0;
    @try {
        NSString *rawStr = [NSString stringWithFormat:@"username=%@",self.txtEmail.text];
        NSData *data = [rawStr dataUsingEncoding:NSUTF8StringEncoding];

        NSURL *url = [NSURL URLWithString:@"http://something.com/register.php"];
        NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];

        [request setHTTPMethod:@"POST"];
        [request setHTTPBody:data];

        NSURLResponse *response;
        NSError *err;
        NSData *responseData = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&err];
        NSLog(@"responseData: %@", responseData);
    }
    @catch (NSException * e) {
        NSLog(@"Exception: %@", e);
        [self alertStatus:@"Sign in Failed." :@"Error!" :0];
    }
    if (success) {
        [self performSegueWithIdentifier:@"login_success" sender:self];
    }
}

This sends to my PHP file in my server

<?php
    $email      =   $_GET['username'];
    $email2      =   $_POST['username'];
    mail('[e-mail]','testing' , $email,$email2);
?>

I tried to test these two functions to send to my email but the email was empty for a reason. Did I went wrong?? Please help me out ty.

The correct answer is :

NSString *rawStr = [NSString stringWithFormat:@"username=%@",self.txtEmail.text];
        NSData *data = [rawStr dataUsingEncoding:NSUTF8StringEncoding];

        NSURL *url = [NSURL URLWithString:@"http://something.com/register.php"];
        NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];

        [request setHTTPMethod:@"POST"];
        [request setHTTPBody:data];

        NSURLResponse *response;
        NSError *err;
        NSData *responseData = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&err];
        NSLog(@"responseData: %@", responseData);
