ScrollView within UITabBarController

I for the life of me still can't get a scrollview to work. I'm going back and redoing my UI in code.

AppDelegate.m

UITabBarController *tabBarController = [[UITabBarController alloc] init];
    WeightCalculatorViewController *weightCalcVC = [[WeightCalculatorViewController alloc] init];
RoundCounterViewController *roundCountVC = [[RoundCounterViewController alloc] init];
    NSArray *controllers = [NSArray arrayWithObjects:weightCalcVC, roundCountVC, nil];
    tabBarController.viewControllers = controllers;
    self.window.rootViewController = tabBarController;
    UITabBarItem *weightCalcTab = [[UITabBarItem alloc] initWithTitle:@"Calculator" image:nil tag:0];
    UITabBarItem *counterTab = [[UITabBarItem alloc] initWithTitle:@"Rounds" image:nil tag:1];
    weightCalcVC.tabBarItem = weightCalcTab;
    roundCountVC.tabBarItem = counterTab;

WeightCalculatorViewController.m

CGRect frameSize = CGRectMake(0, 0, self.view.bounds.size.width, self.view.bounds.size.height);
    self.scrollView = [[UIScrollView alloc] initWithFrame:frameSize];
    self.scrollView.contentSize = CGSizeMake(self.view.bounds.size.width * 2, self.view.bounds.size.height);
    self.scrollView.pagingEnabled = YES;
    self.scrollView.clipsToBounds = NO;
    self.scrollView.backgroundColor = [UIColor whiteColor];
    [self.view addSubview:self.scrollView];

This is the only thing keeping my app from being exactly the way I want it. Please help!

Sorta got it fixed. I was adding subviews to the wrong views. I'll have to check it again once I replace all the UI elements but I think I've got it.
