NSURL *URL = [NSURL URLWithString:[NSString stringWithFormat:#"%#",url]];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:URL];
[request addValue:#"application/json" forHTTPHeaderField:#"Content-Type"];
[request setHTTPMethod: #"POST"];
[NSURLConnection connectionWithRequest:request delegate:self];

NSString *appurl=[NSString stringWithFormat:#"Some URL"];
appurl = [appurl stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
NSMutableURLRequest *request=[NSMutableURLRequest requestWithURL:[NSURL URLWithString:appurl]];
NSData *returnData = [NSURLConnection sendSynchronousRequest:request returningResponse: nil error: nil ];
NSString *returnString = [[NSString alloc] initWithData:returnData encoding: NSUTF8StringEncoding];
NSLog(#"%#",returnString);
OR
NSString *post =[NSString stringWithFormat:#"email=%#&pw=%#",[_txt_email.text lowercaseString],_txt_password.text];
NSData *postData = [post dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];
NSString *postLength = [NSString stringWithFormat:#"%d",[postData length]];
NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease];
[request setURL:[NSURL URLWithString:[NSString stringWithFormat:#"%#login_new.php",app.Main_url]]];
[request setHTTPMethod:#"POST"];
[request setValue:postLength forHTTPHeaderField:#"Content-Length"];
[request setValue:#"application/x-www-form-urlencoded" forHTTPHeaderField:#"Content-Type"];
[request setHTTPBody:postData];
NSError *error;
NSURLResponse *response;
NSData *urlData=[NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];
NSString *str=[[NSString alloc]initWithData:urlData encoding:NSUTF8StringEncoding];
NSLog(#"%#",str);
