🎪 Rideau

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

🚀 Rideau is in release candidate!

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 10.1+ Swift 4.2+

📱 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) { (config) in
  config.snapPoints = [.autoPointsFromBottom, .fraction(0.6), .fraction(1)]
}
  
let someView = ...

rideauView.containerView.set(bodyView: container.view, options: .strechDependsVisibleArea)

Present with Modal Presentation


let targetViewController: YourViewController = ...

let controller = RideauViewController(
  bodyViewController: targetViewController,
  configuration: {
    var config = RideauView.Configuration()
    config.snapPoints = [.autoPointsFromBottom, .fraction(1)]
    return config
}(),
  initialSnapPoint: .autoPointsFromBottom
)

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
}

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

⚙️ Details

RideauContainerView has two ways of resizing content view which is added.

RideauContainerView.ResizingOption
- noResize
- resizeToVisibleArea

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

🔌 Components

Rideau provides the following components that may help us.

RideauMaskedCornerRoundedViewController

A Container view controller that implements masked rounded corner interface and has some options.

More customizable

let targetViewController: YourViewController = ...
let toDisplayViewController = RideauMaskedCornerRoundedViewController(viewController: targetViewController)

let controller = RideauViewController(
  bodyViewController: RideauMaskedCornerRoundedViewController(viewController: target),
  ...
