Dropbox API Uploading a file Uploading a file from NSFileHandle using upload sessions with every error case handled using the SwiftyDropbox library
Example
This uses the SwiftyDropbox library to upload a file from a NSFileHandle to the Dropbox account using upload sessions, handling every error case:
import UIKit
import SwiftyDropbox
class ViewController: UIViewController {
// filled in later in doUpload:
var fileHandle : NSFileHandle? = nil
var data : NSData? = nil
let chunkSize = 5 * 1024 * 1024 // 5 MB
var offset = 0
var sessionId = ""
// replace this with your desired destination path:
let destPath = "/SwiftyDropbox_upload.txt"
override func viewDidLoad() {
super.viewDidLoad()
Dropbox.authorizedClient = DropboxClient(...)
doUpload()
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
}
func doUpload() {
// replace this with the path to the file you want to upload
let filePath = "/path/to/file"
print("Getting file at \(filePath) for uploading...")
fileHandle = NSFileHandle.init(forReadingAtPath: filePath)!
print("Using chunked uploading with chunk size \(chunkSize)...")
uploadFirstChunk()
}
func uploadFirstChunk() {
data = fileHandle!.readDataOfLength(chunkSize)
let size = data!.length
print("Have \(size) bytes to upload.")
Dropbox.authorizedClient!.files.uploadSessionStart(input:data!)
.response { response, error in
if let result = response {
self.sessionId = result.sessionId
self.offset += size
print("So far \(self.offset) bytes have been uploaded.")
self.uploadNextChunk()
} else if let callError = error {
print("uploadSessionStart failed")
