D2PCurvedModal

Example

To run the example project, clone the repo, and run pod install from the Example directory first. The Example project use the modal as a Color/Size Picker.

Installation

D2PCurvedModal is available through CocoaPods. To install it, simply add the following line to your Podfile:

pod 'D2PCurvedModal'

How to Use?

1. First install the Pod and import the module D2PCurvedModal to your file

import D2PCurvedModal

2. Instantiate D2PCurvedModalTransition and D2PCurvedModalPercentDrivenTransition inside the your presenting ViewController

let percentDrivenTransition = D2PCurvedModalPercentDrivenTransition()
let transition = D2PCurvedModalTransition()

3. For the purpose of the transition animation your presenting ViewController must conform the UIViewControllerTransitioningDelegate protocol, with these appropriate methods

extension ViewController: UIViewControllerTransitioningDelegate {
    
    func animationController(forPresented presented: UIViewController, presenting: UIViewController, source: UIViewController) -> UIViewControllerAnimatedTransitioning? {
       
        if presented is D2PCurvedModal {
            transition.opening = true
            return transition
        }
        
        return nil
        
    }
    
    func animationController(forDismissed dismissed: UIViewController) -> UIViewControllerAnimatedTransitioning? {
        
        if dismissed is D2PCurvedModal {
            transition.opening = false
            return transition
        }
        
        return nil
        
        
    }
    
    func interactionControllerForDismissal(using animator: UIViewControllerAnimatedTransitioning) -> UIViewControllerInteractiveTransitioning? {
        
        return percentDrivenTransition.transitionInProgress ? percentDrivenTransition : nil
        
    }
    
}

4. Inside the action method (to open the modal) instantiate the view controllers that will appear embedded into the D2PCurvedModal and instantiate D2PCurvedModal, to finally use the method setUpViewOf(viewController:) of D2PCurvedModal

@IBAction func openModal(_ sender: Any) {

    let myCustomVC = MyCustomVC(nibName: "MyCustomVC", bundle: Bundle(for: MyCustomVC.self))
    let modalVC = D2PCurvedModal(nibName: "D2PCurvedModal", bundle: Bundle(for: D2PCurvedModal.self))
 
    modalVC.setUpViewOf(viewController: myCustomVC)
 
    modalVC.containerHeight = 200
    modalVC.transitioningDelegate = self
    percentDrivenTransition.attachToViewController(viewController: modalVC)
 
    present(modalVC, animated: true, completion: nil)
 
}

That's it! You're all set!!

• modalWillOpen(modalVC: D2PCurvedModal)
  Tells the delegate that the view of the specified modal view controller is about to be displayed.

• modalWillClose(modalVC: D2PCurvedModal)
  Tells the delegate that the view of the specified modal view controller is about to be removed.
