fork 배경

iOS 17 에서 제대로 표시가 되지 않는 이슈를 수정하기 위해 레포 fork 와 별도 유지보수를 시작했습니다.

현재 PanModal 은 마지막 배포가 20년으로, 올라온 PR 들에 대해 관리를 하고 있지 않은 상황입니다.

저희가 따로 필요한 유지보수를 하거나 장기적으론 이 라이브러리 자체에 대한 대응을 고민해야 하는 상태입니다.

Swift 4.2 support can be found on the Swift4.2 branch.

Features

• Supports any type of UIViewController
• Seamless transition between modal and content
• Maintains 60 fps performance

Compatibility

PanModal requires iOS 10+ and is compatible with Swift 4.2 projects.

Installation

• CocoaPods:

pod 'PanModal'

• Carthage:

github "slackhq/PanModal"

• Swift Package Manager:

dependencies: [
  .package(url: "https://github.com/slackhq/PanModal.git", .exact("1.2.6")),
],

Usage

PanModal was designed to be used effortlessly. Simply call presentPanModal in the same way you would expect to present a UIViewController

.presentPanModal(yourViewController)

The presented view controller must conform to PanModalPresentable to take advantage of the customizable options

extension YourViewController: PanModalPresentable {

    var panScrollable: UIScrollView? {
        return nil
    }
}

PanScrollable

If the presented view controller has an embedded UIScrollView e.g. as is the case with UITableViewController, panModal will seamlessly transition pan gestures between the modal and the scroll view

class TableViewController: UITableViewController, PanModalPresentable {

    var panScrollable: UIScrollView? {
        return tableView
    }
}

Adjusting Heights

Height values of the panModal can be adjusted by overriding shortFormHeight or longFormHeight

var shortFormHeight: PanModalHeight {
    return .contentHeight(300)
}

var longFormHeight: PanModalHeight {
    return .maxHeightWithTopInset(40)
}

Updates at Runtime

Values are stored during presentation, so when adjusting at runtime you should call panModalSetNeedsLayoutUpdate()

func viewDidLoad() {
    hasLoaded = true

    panModalSetNeedsLayoutUpdate()
    panModalTransition(to: .shortForm)
}

var shortFormHeight: PanModalHeight {
    if hasLoaded {
        return .contentHeight(200)
    }
    return .maxHeight
}

Contributing

We're glad to be open sourcing this library. We use it in numerous places within the slack app and expect it to be easy to use as well as modify; we've added extensive documentation within the code to support that.

We will only be fixing critical bugs, thus, for any non-critical issues or feature requests we hope to be able to rely on the community using the library to add what they need. For more information, please read the contributing guidelines.
