NSString *request_url = [NSString stringWithFormat: #"http://192.168.18.8/apisample2/friendb.php?fm=jsn&un=%#&pd=%#&gd=%#&ag=%#&st=%#&lf=%#",
user.text, pass.text, gender.text, age.text,status.text,lookfor.text];
NSURL *url = [NSURL URLWithString:request_url];
ASIHttpRequest *request = [ASIHttpRequest requestWithURL:url];
request.delegate = self;
....
HTTP Get method only accept data in url, called query string, so you have to build query string yourself.
