SwipeTransition

SwipeTransition allows trendy transitions using swipe gesture such as "swipe back".

Usage

The easiest way to use

Just setting these frameworks in the Linked Frameworks and Libraries, it works. (if you use Carthage)

Notes: these frameworks use Method Swizzling.

When setting manually without Method Swizzling, please use SwipeTransition.framework only.

Features

• Swipe back anywhere.
• Swipe to dismiss anywhere.
• Apply to all view controllers automatically!

Requirements

• Xcode 9.x
• Swift 4.x
• iOS 8.0+

Installation

Carthage

github "tattn/SwipeTransition"

CocoaPods

pod "SwipeTransition"
pod "SwipeTransitionAutoSwipeBack"      # if needed
pod "SwipeTransitionAutoSwipeToDismiss" # if needed

Swipe back

Configuration

It is possible to disable the feature only for a specific view controller.

class NoSwipeVC: UIViewController {
    override func viewDidAppear(_ animated: Bool) {
        super.viewDidAppear(animated)
        navigationController?.swipeBack?.isEnabled = false
    }

    override func viewDidDisappear(_ animated: Bool) {
        super.viewDidDisappear(animated)
        navigationController?.swipeBack?.isEnabled = true
    }
}

Manually setting

Notes: when you use AutoSwipeBack.framework, these are unnecessary.

Just use SwipeBackNavigationController instead of UINavigationController. Of course, you can set it with Interface Builder.

let viewController = UIViewController()
let navigationController = SwipeBackNavigationController(rootViewControlelr: viewController)

Another way is to set swipeBack.

class CustomNavigationController: UINavigationController {
    override func viewDidLoad() {
        super.viewDidLoad()
        swipeBack = SwipeBackController(navigationController: self)
    }
}

Swipe to dismiss

Configuration

It is possible to disable the feature only for a specific view controller.

class NoSwipeVC: UIViewController {
    override func viewDidAppear(_ animated: Bool) {
        super.viewDidAppear(animated)
        navigationController?.swipeToDismiss?.isEnabled = false
    }

    override func viewDidDisappear(_ animated: Bool) {
        super.viewDidDisappear(animated)
        navigationController?.swipeToDismiss?.isEnabled = true
    }
}

It also works on scroll view.

class ScrollVC: UIViewController, UIScrollViewDelegate {
    @IBOutlet private var scrollView: UIScrollView!
    
    override func viewDidLoad() {
        super.viewDidLoad()
        scrollView.delegate = self
        swipeToDismiss?.setScrollViews([scrollView])
        
        // in case of presenting a navigationController
        // navigationController?.swipeToDismiss?.setScrollViews([scrollView])
    }
}

Manually setting

Notes: when you use AutoSwipeToDismiss.framework, these are unnecessary.

Just use SwipeToDismissNavigationController instead of UINavigationController. Of course, you can set it with Interface Builder.

let viewController = UIViewController()
let navigationController = SwipeToDismissNavigationController(rootViewControlelr: viewController)

Another way is to set swipeToDismiss.

class CustomNavigationController: UINavigationController {
    override func viewDidLoad() {
        super.viewDidLoad()
        modalPresentationStyle = .overFullScreen
        swipeToDismiss = SwipeToDismissController(viewController: self)
    }
}

Common configuration

You can also change the behavior such as animation.

SwipeBackConfiguration.shared.parallaxFactor = 0.6

SwipeToDismissConfiguration.shared.dismissHeightRatio = 0.5

Inheriting the configure class, you can set it with computed property.

class CustomSwipeBackConfiguration: SwipeBackConfiguration {
    override var transitionDuration: TimeInterval {
        get { return 1.5 }
        set { super.transitionDuration = newValue }
    }
}

SwipeBackConfiguration.shared = CustomSwipeBackConfiguration()
