我正在使用SWReveal https://github.com/John-Lluch/SWRevealViewController库来创建侧面菜单应用程序。在主视图控制器中，我有一个mapview，在mapview中，我实现了一个工作正常的底页https://github.com/52inc/Pulley/。然后，我继续将前视图控制器设置为class BottomSheetVC: PulleyViewController {
weak var infoVc: InfoVC!
weak var estimateVc: EstimateVC!
weak var serviceUnavailableVc: ServiceUnavailableVC!
weak var onTripVc: OnTripVC!
weak private var currentViewController: UIViewController? {
didSet {
if let onTripVc = oldValue as? OnTripVC {
// Reset the view if it was showing the cancellation reason view.
// This ensures the cancellation view is not the initial view next time
// this bottom sheet is shown.
onTripVc.setSecondViewVisible(false)
}
if let currentViewController = currentViewController {
setDrawerContentViewController(controller: currentViewController, animated: false)
setNeedsSupportedDrawerPositionsUpdate()
}
}
}
var mode = BottomSheetMode.info {
didSet {
switch mode {
case .info: currentViewController = infoVc
case .estimate: currentViewController = estimateVc
case .serviceUnavailable: currentViewController = serviceUnavailableVc
case .onTrip: currentViewController = onTripVc
}
}
}
}
，我有一个faButton位于mapView的底部，当调整底层时，该fabButton应该重新调整并向上移动，但我无法去做。我已经尝试解决此问题好几天了，但尚未做出回应。以下是我的代码，可以根据要求添加任何内容
...
class ServiceUnavailableVC: BaseBottomSheetVC {
override var mode: BottomSheetMode {
return .serviceUnavailable
}
}
class BaseBottomSheetVC: UIViewController, PulleyDrawerViewControllerDelegate {
var mode: BottomSheetMode {
return .onTrip
}
func collapsedDrawerHeight(bottomSafeArea: CGFloat) -> CGFloat {
return mode.collapsedDrawerHeight
}
func partialRevealDrawerHeight(bottomSafeArea: CGFloat) -> CGFloat {
return mode.partialRevealDrawerHeight
}
func supportedDrawerPositions() -> [PulleyPosition] {
return mode.supportedDrawerPositions
}
}
// MARK: - PulleyPrimaryContentControllerDelegate
extension HomeVC: PulleyPrimaryContentControllerDelegate {
func drawerPositionDidChange(drawer: PulleyViewController, bottomSafeArea: CGFloat) {
guard let drawer = drawer as? BottomSheetVC else { return }
switch drawer.drawerPosition {
case .closed:
if drawer.mode == .estimate {
self.toggleButton.image = Icon.arrowBack
}
case .collapsed:
if drawer.mode == .estimate {
self.toggleButton.image = Icon.close
}
default: break
}
}
func makeUIAdjustmentsForFullscreen(progress: CGFloat, bottomSafeArea: CGFloat) {
}
func drawerChangedDistanceFromBottom(drawer: PulleyViewController, distance: CGFloat,
bottomSafeArea: CGFloat) {
print("DRAWER DISPLAY")
guard let drawer = drawer as? BottomSheetVC else { return }
print("DRAWER DISPLAY \(drawer.currentDisplayMode)")
let distance = distance - bottomSafeArea
if drawer.mode == .estimate || drawer.mode == .onTrip {
mapView.padding = UIEdgeInsets(top: 20, left: 0, bottom: distance, right: 20)
}
else if drawer.mode == .info {
// This fixes a bug where the bottom padding added to the map when the promo bottom
// sheet is visible causes the map pin to be off the center of the map. To fix this,
// add padding to the top and bottom of the map.
mapView.padding = UIEdgeInsets(top: distance, left: 0, bottom: distance, right: 20)
}
else {
mapView.padding = UIEdgeInsets(top: 0, left: 0, bottom: 0, right: 0)
}
fabBottomConstraint.constant = distance + 16
}
}
SheetContent.swift
let storyboard = R.storyboard.baseSB()
let swVC = storyboard.instantiateViewController(withIdentifier: SWRevealViewController.className) as! SWRevealViewController
swVC.loadView()
let homeVC = swVC.frontViewController as! HomeVC
homeVC.mode = AppMode.go
let bottomSheetVC = BottomSheetVC(contentViewController: swVC, drawerViewController: UIViewController())
bottomSheetVC.drawerCornerRadius = 0
bottomSheetVC.initialDrawerPosition = .closed
bottomSheetVC.shadowRadius = 0
bottomSheetVC.shadowOpacity = 0
homeVC.bottomDrawer = bottomSheetVC
bottomSheetVC.modalTransitionStyle = .crossDissolve
self?.present(bottomSheetVC, animated: true, completion: nil)
