Customizable download button with progress and transition animations. It is based on Apple's App Store download button.

ahdownloadbutton's Issues

Unable to leave animationDispatchGroup if app goes to background...

Unable to leave animationDispatchGroup if app goes to background then back...and the UI is stuck with "startDownload" state

AHDownloadButton+StateTransitionAnimation.swift

// My simple fix

//From:
let completion: (Bool) -> Void = { completed in
    guard completed else { return }
    self.resetStateViews(except: newState)
    self.animationDispatchGroup.leave()
}

//To:
let completion: (Bool) -> Void = { completed in
    self.resetStateViews(except: newState)
    self.animationDispatchGroup.leave()
    guard completed else { return }
}

Can't tap AHDownloadButton which is inside UICollectionViewCell

Button is added inside awakeFromNib

override func awakeFromNib() {
        super.awakeFromNib()

        buttonContainer.addSubview(downloadButton)
        downloadButton.snp.makeConstraints { (maker) in
            maker.leading.trailing.equalToSuperview()
            maker.top.equalToSuperview().offset(2)
            maker.bottom.equalToSuperview().offset(2)
        }
    }

but next delegate function isn't called after tap on button

extension FileViewCell: AHDownloadButtonDelegate {
    func downloadButton(_ downloadButton: AHDownloadButton, tappedWithState state: AHDownloadButton.State) {...}
}

The workaround is to use touch API:

override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
        for touch in touches {
            if touch.view == downloadButton {
                downloadButton(downloadButton, tappedWithState: downloadButton.state)
                break
            }
        }
    }

But it only makes button container UIView tappable:

@IBOutlet weak var buttonContainer: UIView!

I had a feeling that overriding hitTest somehow could help, but not sure completely, will be thankful if somebody will help to understand what is the proper way of using this button inside collection cell

SwiftUI

Hey @amerhukic,

Any plans of re writing it to SwiftUI? Would be amazing! : )

[Storyboard] Unknown class _TtC6Y5Lock16AHDownloadButton in Interface Builder file

Tried almost eveything. Still getting this error.
