Tabbar Controller with swipe effect - iphone

Question

I'm trying to do a Tabbar Controller like below effect:
By swiping an viewcontroller will redirect to next tab. How can we achieve this in iOS? Is there any other controls to do like this?

Answer 1

Just add UISwipeGestureRecognizer to your tabBarView controller and change your tabBar index after swipe.
swipeRecognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:self
action:#selector(swipeMethod:)];
swipeRecognizer.direction = UISwipeGestureRecognizerDirectionRight | UISwipeGestureRecognizerDirectionLeft;
[self addGestureRecognizer:swipeRecognizer];
And my method to handle swipe is :
-(void)swipeMethod: (UISwipeGestureRecognizer *) sender
{
NSLog(#"Swipe!");
}
EDIT
Or you can use UIScrollView with paging enable and UIView to display your data.

Answer 2

There is a library for this on GitHub, it is called MGSwipeTabBarController and is designed to do exactly what you are looking for.
It is as simple as :
NSArray *viewControllers = . . . //your view controllers
MGSwipeTabBarController *swipeController = [[MGSwipeTabBarController alloc] initWithViewControllers:viewControllers];
Please Note that it is only compatible with iOS7 and + and that you'll still need to design your own tab bar that respond to scroll events using the MGSwipeTabBarControllerDelegateprotocol.

https://github.com/nicklockwood/SwipeView
you can use this class to achieve your goal...
or else you have to make animation for tap on tabbar using following method,
[UIView transitionFromView:<#(UIView *)#> toView:<#(UIView *)#> duration:<#(NSTimeInterval)#> options:<#(UIViewAnimationOptions)#> completion:<#^(BOOL finished)completion#>]

If anyone is still looking you can find another implementation here on this youtube series

Edit:
So to my knowledge and according to the video, the idea is that you'll want to use two UICollectionViews in one view controller. One collection view to display the content (apps) and the other for the horizontal navigation containing the categories.
To create the green 'highlight' bar you can use a UIView and adjust the height/width of the bar using constraints - heightAnchor/widthAnchor and add that to the navigation bar.
To get the bar moving with the distance the user will swipe, there is a method you can override to capture the horizontal scrolling called scrollViewDidScroll. From here you'll want to provide a variable from your the UIView's constraint (of type NSLayoutConstraint) to be able to update the x position of the UIView
override func scrollViewDidScroll(_ scrollView: UIScrollView)
{
print(scrollView.contentOffset.x)
menuBar.myGreenBarLeftConstraint.constant = scrollView.contentOffset.x / 4
//or however many categories you have
}
