Usage

When displaying popup in another window, please call first PopupWindowManager changeKeyWindow(rootViewController: UIViewController)

PopupWindowManager.shared.changeKeyWindow(rootViewController: UIViewController())

Create and show show

Create a PopupItem in the ViewController where you want to display the popup and call the method of BasePopupViewController

let popupOption = PopupOption(shapeType: .roundedCornerTop(cornerSize: 8), viewType: .toast, direction: .bottom)
let popupItem = PopupItem(view: loginView,
                          height: Const.firstViewFrame.height,
                          maxWidth: 500,
                          popupOption: popupOption)

First popup implementation is included in BasePopupViewController's loadView, viewDidAppear.
If you want to create the next popup, please call showPopupView().

class SampleViewController: BasePopupViewController {
    override open func loadView() {
        super.loadView()
        setupPopupContainerView()
    }

    override open func viewDidAppear(_ animated: Bool) {
        super.viewDidAppear(animated)
        makePopupView(with: item)
        showPopupView(duration: item.duration, curve: .easeInOut, delayFactor: 0.0)
    }
}

Transform & Replace

Replace the display contents, and perform deformation to the specified size.
By using PopupItem, you can specify content contents and size.

transformPopupView(duration: Const.transformDuration, curve: .easeInOut, popupItem: popupItem) { [weak self] _ in
    guard let me = self else { return }
    me.replacePopupView(with: popupItem)
    me.dismissPopupView(duration: 3.3, curve: .easeInOut, delayFactor: 0.9, direction: .top) { _ in }
}

Dismiss

Specify hide animation direction with PopupViewDirection

dismissPopupView(duration: 3.3, curve: .easeInOut, delayFactor: 0.9, direction: .bottom) { _ in
    PopupWindowManager.shared.changeKeyWindow(rootViewController: nil)
}

PopupItem

PopupItem and PopupOption are struct to set up a popup, View, size, direction, whether it is rounded, margin, blurred or not, duration, maxWidth, type

public struct PopupItem {
    public let view: UIView
    public let height: CGFloat
    public let maxWidth: CGFloat
    public let landscapeSize: CGSize?
    public let popupOption: PopupOption
}

public struct PopupOption {
    public let shapeType: ShapeType
    public let viewType: ViewType
    public let direction: PopupViewDirection
    public let margin: CGFloat
    public let hasBlur: Bool
    public let duration: TimeInterval
    public let canTapDismiss: Bool
}

Landscape

maxWidth

By setting maxWidth with popupitem's initializer, you can set the maximum width of the popup in landscape mode.

You can set popup size at landscape.
