Dropbox API Downloading a file Downloading a file with progress information using the SwiftyDropbox library
Example
Adapted from the tutorial, this uses the SwiftyDropbox library to download a file, with a progress callback on the download method to get progress information:
// Download a file
let destination : (NSURL, NSHTTPURLResponse) -> NSURL = { temporaryURL, response in
let fileManager = NSFileManager.defaultManager()
let directoryURL = fileManager.URLsForDirectory(.DocumentDirectory, inDomains: .UserDomainMask)[0]
// generate a unique name for this file in case we've seen it before
let UUID = NSUUID().UUIDString
let pathComponent = "\(UUID)-\(response.suggestedFilename!)"
return directoryURL.URLByAppendingPathComponent(pathComponent)
}
Dropbox.authorizedClient!.files.download(path: "/path/to/Dropbox/file", destination: destination)
.progress { bytesRead, totalBytesRead, totalBytesExpectedToRead in
print("bytesRead: \(bytesRead)")
print("totalBytesRead: \(totalBytesRead)")
print("totalBytesExpectedToRead: \(totalBytesExpectedToRead)")
}
.response { response, error in
if let (metadata, url) = response {
print("*** Download file ***")
print("Downloaded file name: \(metadata.name)")
print("Downloaded file url: \(url)")
} else {
print(error!)
}
}
You can then use that raw progress information to back the progress UI in your app.
