(1) Setup PullToDismiss
import PullToDismiss
class SampleViewController: UIViewController {
@IBOutlet private weak var tableView: UITableView!
private var pullToDismiss: PullToDismiss?
override func viewDidLoad() {
super.viewDidLoad()
pullToDismiss = PullToDismiss(scrollView: tableView)
}
}(2) Create view controller and set modalPresentationStyle. Then present view controller
let vc = SampleViewController()
let nav = UINavigationController(rootViewController: vc)
nav.modalPresentationStyle = .overCurrentContext
self.present(nav, animated: true, completion: nil)👍👍👍
You can use all scroll view's delegate by set pullToDismiss.delegate.
import PullToDismiss
class SampleViewController: UIViewController {
@IBOutlet private weak var tableView: UITableView!
private var pullToDismiss: PullToDismiss?
override func viewDidLoad() {
super.viewDidLoad()
pullToDismiss = PullToDismiss(scrollView: tableView)
pullToDismiss?.delegate = self
}
}
extension SampleViewController: UITableViewDelegate {
func scrollViewDidScroll(_ scrollView: UIScrollView) {
// ...
}
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
// ...
}
}You can customize backgroundEffect, dismissableHeightPercentage:
- background (default:
ShadowEffect.default, [color: black, alpha: 0.8])
pullToDismiss?.background = ShadowEffect(color: .red, alpha: 0.5) // color: red, alpha: 0.5New feature for v1.0.
// preset blur (.extraLight, .light, .dark)
pullToDismiss?.background = BlurEffect.extraLight
// set custom Blur
pullToDismiss?.background = BlurEffect(color: .red, alpha: 0.5, blurRadius: 40.0, saturationDeltaFactor: 1.8)
// to pull half size of view controller, dismiss view controller.
pullToDismiss?.dismissableHeightPercentage = 0.5- iOS 8.0+ (blur effect: iOS 9.0+)
