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: 0.5
New 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.
