🎪 Rideau

Rideau is a drawer UI similar to what Apple's apps use. (e.g Maps, Shortcuts)

Overview

• 💎 Supports multiple snap points (e.g. most hidden, half visible, full visible, and we can add more snap points.)
• 💎 Supports Animations alongside moving (e.g. dimming background color)
• 💎 Supports handling scrolling of scrollview inside RideauView
• 💎 Supports resizing based on intrinsic content size of view that RideauView has
• ✅ Interactive Animations come from UIViewPropertyAnimator, with this it's actual interruptible animation and no glitches. (it can't get from UIView.animate)

RideauView allows for flexible snap points. Snap points pertains to specified offsets where the draggable view "snaps to" when the dragging has ended. There are usually 2 or 3 snap points.

---

Objects we will commonly use:

• RideauView
• RideauViewController
• RideauSnapPoint

RideauView is the core object in this library. We typically add our own view to RideauView.

RideauViewController contains a RideauView. It allows us to present the RideauView as modal dialog.

RideauSnapPoint defines where the content view stops.

🔶 Requirements

iOS 10.0+ Xcode 13+ Swift 5.5+

📱 Features

• Multiple snap-point
• Smooth integration with dragging and UIScrollView's scrolling.
• Tracking UIScrollView automatically
• Set UIScrollView to track manually
• Use UIViewPropertyAnimator between snap-points.

👨🏻‍💻 Usage

Present inline

let rideauView = RideauView(
  frame: .zero,
  configuration: .init { config in
    config.snapPoints = [.autoPointsFromBottom, .fraction(0.6), .fraction(1)]
  }
)

let someView: UIView = ...

rideauView.containerView.set(
  bodyView: someView,
  resizingOption: .resizeToVisibleArea
)

Present with Modal Presentation

let targetViewController: YourViewController = ...

let controller = RideauViewController(
  bodyViewController: targetViewController,
  configuration: .init { config in
    config.snapPoints = [.autoPointsFromBottom, .fraction(1)]
  },
  initialSnapPoint: .autoPointsFromBottom,
  resizingOption: .resizeToVisibleArea
)

present(controller, animated: true, completion: nil)

Multiple SnapPoints

We can define snap-point with RideauSnapPoint.

public enum RideauSnapPoint: Hashable {

  case fraction(CGFloat)
  case pointsFromTop(CGFloat)
  case pointsFromBottom(CGFloat)
  case autoPointsFromBottom

  case hidden

  public static let full: RideauSnapPoint = .fraction(1)
}

config.snapPoints = [.pointsFromBottom(200), .fraction(0.5), .fraction(0.8), .fraction(1)]

⚙️ Details

RideauContentContainerView has two ways of resizing the content view that is added.

• RideauContentContainerView.ResizingOption
  • noResize
  • resizeToVisibleArea

public final class RideauContentContainerView: UIView {
  public func set(bodyView: UIView, resizingOption: ResizingOption)
}

🔌 Components

Rideau provides the following components that may help us.

  bodyViewController: RideauMaskedCornerRoundedViewController(viewController: targetViewController),
  configuration: .init { config in
    config.snapPoints = [.autoPointsFromBottom, .fraction(1)]
  },
  initialSnapPoint: .autoPointsFromBottom,
  resizingOption: .resizeToVisibleArea
)
