UISegmentController and UIViews

Question

I would like to know how to correctly operate with two views by UISegmentController.

Now I have two UIViews and UISegmentController and procedure changeView:

- (void)changeView:(NSInteger)index {
switch (index) {
    case 0:
        self.recipeInfoView.alpha = 1;
        self.recipeInfoView2.alpha = 0;
        break;
    case 1:
        self.recipeInfoView.alpha = 0;
        self.recipeInfoView2.alpha = 1;
        break;

    default:
        break;
}

This code works, but each view have the same position and size and very uncomfortable to work with it. I'm using storyboards.

First write following code For create UISegmentedControl and give color of your UIView.

- (void)viewDidLoad
{
    [super viewDidLoad];
       
   //Make hide of your UIView 
       self.recipeInfoView.hide = YES;
       self.recipeInfoView2.hide = YES;

  //Give color of your UIView
       self.recipeInfoView.backgroundColor = [UIColor redColor];
       self.recipeInfoView.backgroundColor = [UIColor blackColor];

  //Create UISegmentedControl Controller 
    NSArray *itemArray = [NSArray arrayWithObjects: @"FirstView", @"SecondView", nil];
    self.segmentedControl= [[UISegmentedControl alloc] initWithItems:itemArray];
    self.segmentedControl.frame = CGRectMake(35, 100, 250, 33);
    self.segmentedControl.segmentedControlStyle = UISegmentedControlStyleBar;
    self.segmentedControl.momentary=NO;
    self.segmentedControl.tintColor=[UIColor darkGrayColor];

    [self.segmentedControl addTarget:self action:@selector(segmentAction:) forControlEvents:UIControlEventValueChanged];
    
    [self.view addSubview:self.segmentedControl];
   
}

// segmentAction Methods

- (IBAction)segmentAction:(id)sender
{
    if([sender selectedSegmentIndex] == 0)
    {
       if(self.recipeInfoView.isHidden == YES)
          self.recipeInfoView.Hidden == NO;
      else
          self.recipeInfoView.Hidden == NO;

      if(self.recipeInfoView2.isHidden == YES)
           self.recipeInfoView2.Hidden == YES;
      else
           self.recipeInfoView2.Hidden == YES;

   }
   else if([sender selectedSegmentIndex] == 1)
   {
       if(self.recipeInfoView2.isHidden == YES)
           self.recipeInfoView2.Hidden == NO;
       else
           self.recipeInfoView2.Hidden == NO;

       if(self.recipeInfoView.isHidden == YES)
            self.recipeInfoView.Hidden == YES;
       else
           self.recipeInfoView.Hidden == YES; 

    }
}
