    NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
    [defaults setObject:uName forKey:@"uName"];
    [defaults setObject:pWord forKey:@"pWord"];
    [defaults synchronize];
    NSLog(@"Data Saved");
    NSString *post = [NSString stringWithFormat:@"&Username=%@&Password=%@", userName.text, password.text];
    NSData *postData = [post dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];
    NSString *postlength = [NSString stringWithFormat:@"%d", [postData length]];
    NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
    [request setURL:[NSURL URLWithString:[NSString stringWithFormat:@"myurl"]]];
    [request setHTTPMethod:@"POST"];
    [request setValue:postlength forHTTPHeaderField:@"Content-Length"];
    [request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Current-Type"];
    [request setHTTPBody:postData];
    NSURLConnection *conn = [[NSURLConnection alloc]initWithRequest:request delegate:self];

    if(conn){
        if(conn){
            MainView *mainView = [[MainView alloc]initWithNibName:@"MainScreen" bundle:nil];
            self.mView = mainView;
        }
        NSLog(@"Connection successful");
    }
    else{
        NSLog(@"Connection failed");
    }   
}

You need to add the new view as a subview to show it. This will work if the class calling is the main view controller class:

if(conn){
        MainView *mainView = [[MainView alloc]initWithNibName:@"MainScreen" bundle:nil];
        self.mView = mainView;
       [self.view addSubview: mainView.view];
    }
