connectionDidResumeDownloading(_:totalBytesWritten:expectedTotalBytes:)
Sent to the delegate when an URL connection resumes downloading a URL asset that was earlier suspended.
Declaration
optional func connectionDidResumeDownloading(_ connection: NSURLConnection, totalBytesWritten: Int64, expectedTotalBytes: Int64)Parameters
- connection:
The URL connection object downloading the asset.
- totalBytesWritten:
The total number of bytes of the downloading asset that have been written to the destination file.
- expectedTotalBytes:
The total number of bytes of the URL asset once it is completely downloaded and written to a file.
Discussion
This method is invoked once a suspended download of a URL asset resumes downloading. In response, the delegate can display a progress indicator, setting the initial value of the indicator to where it was when downloading was suspended. After the URL-connection object sends this message, it sends one or more connection(_:didWriteData:totalBytesWritten:expectedTotalBytes:) to the delegate until the download concludes.
