}

i think u r in wrong way!!

u store user name , password in global variable,and push posting page

(ibaction) submit: (id) sender {

user_name=uname.text; password=password.text;

twitter *controller = [[twitter alloc] init]; [self.navigationcontroller pushviewcontroller:controller animated:yes]; [controller release];

}
