使用

注意：为了更好的理解使用，请查看工程示例。

监听下载状态和进度

func addNotification() {
    NotificationCenter.default.addObserver(self, selector: #selector(downloadStateChange(_:)), name: CXDownloadConfig.stateChangeNotification, object: nil)
    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)
}

下载

• 默认下载目录和文件名

CXDownloadManager.shared.download(url: urls[0])

downloadButton1.dl.download(url: urls[0])

• 自定义下载目录和文件名

CXDownloadManager.shared.download(url: urls[1], toDirectory: "Softwares", fileName: "MacDict_v1.20.30.dmg")

downloadButton2.dl.download(url: urls[1], toDirectory: "Softwares", fileName: "MacDict_v1.20.30.dmg")

暂停

CXDownloadManager.shared.pause(url: urls[0])

pauseButton1.dl.pauseTask(url: urls[0])

取消

CXDownloadManager.shared.cancel(url: urls[0])

cancelButton1.dl.cancelTask(url: urls[0])

删除下载文件

CXDownloadManager.shared.deleteTaskAndCache(url: urls[0])
CXDownloadManager.shared.deleteTaskAndCache(url: urls[1], atDirectory: "Softwares", fileName: "MacDict_v1.20.30.dmg")

deleteButton1.dl.deleteTaskAndCache(url: urls[0])
deleteButton2.dl.deleteTaskAndCache(url: urls[1], atDirectory: "Softwares", fileName: "MacDict_v1.20.30.dmg")
