I have the following scenario:

UITabBarController
--tab1
--tab2
----UINavigationController (with a UITableViewController and 3 rows)
------pushedViewController
--tab3
--tab4
--tab5

Ok, so, when user clicks on an option in the UINavigationViewController it pushes "pushedViewController", and in that viewcontroller I want to have a segmented control like the one on the App Store https://i.stack.imgur.com/hrdxL.png

How can I do this?

I already checked

This could help me but I can't figure out how Switch between UIViewControllers using UISegmentedControl

And this user asked the same but it doesn't have the full code Recreating Segmented Control from iPhone App Store

The pushedViewController can contain a UIScrollView framed to fill the screen. Set paging enabled, and give it three big subviews, like this:

CGFloat width = self.view.bounds.width;
CGFloat height = self.view.bounds.height;

// it's easier to do all this this in xib/storyboard, but to illustrate...

self.scrollView.frame = CGRectMake(0,0,width,height);
self.scrollView.contentSize = CGSizeMake(width*3.0, height);  // this must be done in code
self.scrollView.pagingEnabled = YES;

UIView *subviewA, *subviewB, subviewC;

subviewA.frame = CGRectMake(0.0, 0.0, width, height);
subviewB.frame = CGRectMake(0.0, width, width, height);
subviewB.frame = CGRectMake(0.0, 2.0*width, width, height);

[self.scrollView addSubview:subviewA];
[self.scrollView addSubview:subviewB];
[self.scrollView addSubview:subviewC];

// then when the segmented control changes ...

- (IBAction)segmentedControlChanged:(UISegmentedControl *)sender {

    NSInteger page = sender.selectedSegmentIndex;
    CGFloat contentOffsetX = page*self.view.bounds.width;
    [self.scrollView setContentOffset:CGPointMake(contentOffsetX, 0.0) animated:YES];
}

  • Nice, I'll give it try but I think that this is going to be a little problematic because I want to add UIViewControllers that have UITableView and I don't know exactly how are they going to behave. – estemendoza May 06 '12 at 03:15
  • Yes. I meant to add something to my answer about that. This is for full screen views, controlled by the same view controller. 3 view controllers controlled by a segmented control is really a tab bar controller. If you want the tabs at the top, want them to look like a segmented button, want the VCs to slide, etc. Then you're basically deciding to implement your own container view controller (probably not even a tab bar vc subclass). This is a pretty large undertaking. Best of luck. – danh May 06 '12 at 03:20
