VoiceOver Accessibility

[awall1]

Currently, it doesn't seem that there is any compatibility for VoiceOver. I've played with adding these lines into PKHUD, but that's not enough (or always the right) context for each PKHUD type.

init() {
    ...
    self.container.accessibilityLabel = "In progress, please wait."
    UIAccessibilityPostNotification(UIAccessibilityLayoutChangedNotification, self.container)
}

I've also tried setting the label for each Content View type in HUD, but then the UIAccessibilityPostNotification(...) doesn't work when trying to set the focus on the container.

fileprivate extension UIView {
    fileprivate func setAccessibilityProperties(for content: HUDContentType) {
        self.accessibilityLabel = "Please wait."
        switch content {
        case .success:
            self.accessibilityLabel = "Success!"
        case .error:
            self.accessibilityLabel = "Error!"
        case .image(_),
             .rotatingImage(_):
            self.accessibilityLabel = "Image"
        case .label(let title):
            guard let label = title else { break }
            self.accessibilityLabel = label
        case .labeledSuccess(let title, let subtitle),
             .labeledError(let title, let subtitle),
             .labeledProgress(let title, let subtitle),
             .labeledImage(_, let title, let subtitle),
             .labeledRotatingImage(_, let title, let subtitle):
            guard title != nil || subtitle != nil else { break }
            self.accessibilityLabel = (title ?? "") + "\n" + (subtitle ?? "")
        default:
            self.accessibilityLabel = "In progress, please wait."
        }
    }
}

Suggestions?

I created the PR: #213 to address this.
