Switching ViewControllers with UISegmentedControl in iOS5

by

This code works pretty well for your purpose, I use it for one of my new apps.
It uses the new UIViewController containment APIs that allow UIViewControllers inside your own UIViewControllers without the hassles of manually forwarding stuff like viewDidAppear:

- (void)viewDidLoad {
    [super viewDidLoad];
    // add viewController so you can switch them later. 
    UIViewController *vc = [self viewControllerForSegmentIndex:self.typeSegmentedControl.selectedSegmentIndex];
    [self addChildViewController:vc];
    vc.view.frame = self.contentView.bounds;
    [self.contentView addSubview:vc.view];
    self.currentViewController = vc;
}
- (IBAction)segmentChanged:(UISegmentedControl *)sender {
    UIViewController *vc = [self viewControllerForSegmentIndex:sender.selectedSegmentIndex];
    [self addChildViewController:vc];
    [self transitionFromViewController:self.currentViewController toViewController:vc duration:0.5 options:UIViewAnimationOptionTransitionFlipFromBottom animations:^{
        [self.currentViewController.view removeFromSuperview];
        vc.view.frame = self.contentView.bounds;
        [self.contentView addSubview:vc.view];
    } completion:^(BOOL finished) {
        [vc didMoveToParentViewController:self];
        [self.currentViewController removeFromParentViewController];
        self.currentViewController = vc;
    }];
    self.navigationItem.title = vc.title;
}

- (UIViewController *)viewControllerForSegmentIndex:(NSInteger)index {
    UIViewController *vc;
    switch (index) {
        case 0:
            vc = [self.storyboard instantiateViewControllerWithIdentifier:@"FooViewController"];
            break;
        case 1:
            vc = [self.storyboard instantiateViewControllerWithIdentifier:@"BarViewController"];
            break;
    }
    return vc;
}

I got this stuff from chapter 22 of Ray Wenderlichs book iOS5 by tutorial.
Unfortunately I don’t have a public link to a tutorial. But there is a WWDC 2011 video titled “Implementing UIViewController Containment”

EDIT

self.typeSegmentedControl is outlet for your UISegmentedControl

self.contentView is outlet for your container view

self.currentViewController is just a property that we’re using to store our currently used UIViewController
