How to customize bottom view in SBUFileViewer?

Guide & Snippet

• About image detail view trash icon, there is no public interface to handle the delete button, but there is SBUFileViewer/bottomView which contains trash icon.
• So, I recommend that override openFile(fileMessage:) and set SBUFileViewer/bottomView to customized bottom view inside of the method.

override func openFile(fileMessage: FileMessage) {
    self.willPresentSubview()

    SBULoading.start()
    let fileType = SBUUtils.getFileType(by: fileMessage)
    switch fileType {
    case .image:
        let viewer = SBUFileViewer(fileMessage: fileMessage, delegate: self)
        viewer.bottomView = CustomFileViewerBottomView() // 👈 here!
        let naviVC = UINavigationController(rootViewController: viewer)
        self.present(naviVC, animated: true)

    case .etc, .pdf, .video, .audio:
        // please refer to the original sources
    default:
        break
    }
}
