    NotificationCenter.default.addObserver(self, selector: #selector(downloadProgressChange(_:)), name: CXDownloadConfig.progressNotification, object: nil)
}

@objc func downloadStateChange(_ noti: Notification) {
    guard let downloadModel = noti.object as? CXDownloadModel else {
        return
    }
    if downloadModel.state == .finish {
        CXDLogger.log(message: "filePath: \(downloadModel.localPath ?? "")", level: .info)
    } else if downloadModel.state == .error || downloadModel.state == .cancelled {
        if let stateInfo = downloadModel.stateInfo {
            CXDLogger.log(message: "error: \(stateInfo.code), message: \(stateInfo.message)", level: .info)
        }
    }
}

@objc func downloadProgressChange(_ noti: Notification) {
    guard let downloadModel = noti.object as? CXDownloadModel else {
        return
    }
    CXDLogger.log(message: "[\(downloadModel.url)] \(Int(downloadModel.progress * 100)) %", level: .info)
}
